If you consider yourself a developer this flexible piece of UAS hardware is for you. If you enjoy writing software and consider yourself an early adopter this is the board to use. Have fun implementing and extending the already great features. To show of your work and also to ask questions, you are welcomed on the paparazzi mailinglist, this Wiki and the freenode paparazzi IRC channel. This nice piece of hardware can be used for various purposes. Ofcourse as an Autopilot board, but only by uploading another firmware also a servo extension board and more. A good idea of how this nice piece of hardware looks like is shown on the Photos here. If you are not so interested in all of this at the moment since you just have this shiny new board on you desk and want to connect and fly the thing, then go to the page [[Lisa/M/Tutorial/FixedWing| using the board as an '''Autopilot''' for an airplane]] or go [[Lisa/M/Tutorial/RotorCraft|here for uses a an '''Autopilot''' in a quadrotor]]
'''NOTE: THERE IS A [[Lisa/M_v20|NEW VERSION OF LISA/M AVAILABLE]]'''


[[Image:Lisa_M_V1_0_top_with_coin.jpg|thumb|Lisa/M V1.0 top view]]
Lisa/M is a small, general purpose autopilot designed with flexibility across multiple applications in mind. Small weight and size, with (optional) integrated [[AspirinIMU | Aspirin IMU]] and full size 0.1" servo headers make the Lisa/M suitable for both fixed-wing and rotorcraft vehicles. This autopilot is based on the STM32 for improved peripherals and faster processing.

== Changes between v1.0 and v1.1 ==
* Removed pull-ups on the USB gpio
* Removed pull-ups on the CAN gpio
* Connected usb_vbus to pa9 (needed by the USBotg)
* Removed USB pullup transistor as usbotg has a built in pullup
* Swapped UART1 with UART3 (uart1 was used for gps and pa9 was it's tx line, to be able to talk to the gps unit uart3 is a better choice, as uart1 only has an rx line now it is a better choice for spektrum RX modules)
* Removed USART3 TX gpio from the GPIO connector and moved to the GPS connector
* Added voltage selector jumpers to the RC RX connector; to enable powering of 3v3 or an 5v receivers
* Replaced vertical board solution with through hole servo pin headers (easier assembly)
* Servo connectors are in groups of two; for easier assembly
* Servo VBUS is connected together on all four layers; for lower resistance
* Moved LED's from under the analog2 connector; to be able to populate LED's and the connector
* Moved the RC RX connector a bit; to prevent crashing with the jtag plug
* Added one additional servo connector; now we have all 8 accessible through the standard servo connectors
* Fixed servo channel labeling to start at '''S0''' as it is the case on TWOG and Tiny autopilot boards
* Added secondary through hole picoblade USB connector for easier routing of USB inside an airframe

= Hardware update requests =
* REQ: Replace BMP085 with MS5611 (the MS5611 seems to be better in performance then the BMP but it is more expensive and seems to be more difficult to obtain.
** A: It is considered as an update to a future version of lisa/m not V2.0 --[[User:Esden|Esden]] 02:24, 18 November 2011 (CET))

= Usage scenarios =


For regular Autopilot boards a full Lisa/M board is needed. For some scenarios just a basic Lisa/M without [[Inertial_Measurement_Units|IMU]] and [[Airspeed_sensor|pressure sensor]] is needed, this makes the board cheaper of course.

== As a basic Autopilot ==


To use the Lisa/M as an autopilot, we need to attach a GPS receiver. A nice [[GPS#u-Blox_LEA_Series_Receivers|uBlox LEA-5H]] or newer will perform great.

== As and advanced Autopilot ==


Also an external airspeedsensor like the Eagletree would enhance a fixedwing airframe. Ofcourse an extention cable from microUAS to Mini USB to the outside of the airframe is very practical.

== As a servo extender ==


Sometimes being able to steer seven actuators is just not enough. One need for example flaps that enhance aileron or an airbrake and automatic landingfacility. Maybe special ACL lights, or four cameras with zoom. By using a coupled second basic Lisa/M and connect this to the master AP board we can extend our amount of servos.
=== Jumper Configuration ===
There are a number of jumpers on Lisa/M used to configure voltage levels and power input.

Maybe you have a need only to log all kinds of data, like temperature, volts, amps, height, airspeed only. For this we can setup a Lisa/M board. Then we are flexible and add whatever sensors we want. Collecting this data can be to a storage medium like an micro SD card. Sometimes there is no need for realtime data collection but just for storing a huge dataset.

=== Powering the Board ===


[[Image:LisaM_V1_0_top_labeled.png|700px]]
The 3.3V regulator on Lisa/M is a [http://www.micrel.com/page.do?page=/product-info/products/mic5209.shtml MIC5209-3.3YM] capable of delivering up to 500mA. While it is possible to power this regulator with up to 16V, experience has shown that this regulator can become very hot in operation with high input voltages, resulting in potential thermal shutdown while in flight. Depending on the expected current draw, it is best to power this regulator with a lower voltage. 5V is the perfect choice.


= Schematic =
The onboard 5V regulator on Lisa/M is a [http://www.national.com/pf/LP/LP2992.html LP2992], a low-noise, low-dropout linear regulator capable of delivering up to 250mA. This regulator can be bypassed with JP3, connecting the autopilot V_IN bus directly to the autopilot 5V bus if, for example, one is using an external 5V regulated supply.

== Upload firmware ==
 
Uploading firmware onboard USB is not possible with this boart. The boords need hardware modification to make it possible. A very nice way to upload, a.k.a. flashing new Paparazzi code to the board is to use a [[Lisa/M#JTAG|JTAG]] adapter. Less convenient since it takes a special adapter. But this adapter makes it more convenient when testing; one does not need to repower the board to reflash. And flashing via JTag cable is very fast. Also debugging the autopilot is very handy with JTAG.

* While using the USB interface you need to have UART1_TX connected to 3v3 or USB_VBUS (This means you can not transfer data to the GPS while using USB)
* Optionally you can also remove R14 and Q2
 
The GPS UART (UART1) and USB collision was fixed as of Lisa/M v2.0 where the usage of UART1 was swapped with UART3.
 
To use Luftboot on Lisa/M 1.0 then follow instructions for [[Luftboot]] after these hardware modifications.

THE LISA/M v2.0 IS NOW AVAILABLE

Lisa/M V1.0 top view

NOTE: THERE IS A NEW VERSION OF LISA/M AVAILABLE

Lisa/M is a small, general purpose autopilot designed with flexibility across multiple applications in mind. Small weight and size, with (optional) integrated Aspirin IMU and full size 0.1" servo headers make the Lisa/M suitable for both fixed-wing and rotorcraft vehicles. This autopilot is based on the STM32 for improved peripherals and faster processing.

A number of tutorials are being prepared for getting started with Lisa/M:

Hardware Revision History

Version # Release Date Release Notes
v1.0 MM/YYYY Lisa/M Initial Production Release
v0.1 MM/YYYY Initial prototype of Lisa/M

For detailed hardware revision history, please see below.

Features

Lisa/M is based on the 64 pins STM32F105RCT6 connectivity line family processor featuring 64k of RAM and 256k of FLASH. All the pins are exposed, providing access to the complete set of the STM32 peripherals. NOTE: This MCU is different from LISA/L. Lisa/L is based on the 64 pins STM32F103RE processor featuring 64k of RAM and 512k of FLASH, which is part of the high-density performance line family.

  • STM32 microcontroller STM32F105RCT6 datasheet with 256kB flash and 64kB RAM
  • Pressure sensor BMP085
  • 7 x Analog input channels
  • 3 x Generic digital in-/out-puts
  • 2 x 3.3V TTL UART (5V tolerant)
  • 7 x Servo PPM outputs
  • 1 x CAN bus
  • 1 x SPI bus
  • 1 x I2C bus
  • 1 x Micro USB
  • 4 x status LEDs with attached test point
  • 10.8 grams (0.4 oz) (with Aspirin IMU mounted)
  • 9.9 grams (0.35 oz) (without Aspirin IMU mounted)
  • ~33mm x ~56mm x ~10mm
  • 4 layers PCB design

with mounted Aspirin IMU has the following additional sensors on board:

  • 3 Axis Gyroscope
  • 3 Axis Accelerometer
  • 3 Axis Magnetometer

The pressure sensor is mounted directly on the board as this sensor is not provided by Aspirin (v0.1 - v1.1).

In short, you only need to add a high quality GPS module and then you have all necessary sensors for full attitude and altitude stabilization in an extremely small package.

Jumper Configuration

There are a number of jumpers on Lisa/M used to configure voltage levels and power input.

  • Lisa/M v1.0 Top Jumpers and LEDs

  • Lisa/M v1.0 Bottom Jumpers


Power Jumper Configuration
Jumper Bus Connection Default Description
JP1 SERVO_BUS to V_IN CLOSED Connects servo header voltage rail SERVO_BUS to autopilot input voltage V_IN rail
JP2 V_BAT to V_IN OPEN Connects I2C1/CAN rail V_BAT to autopilot input voltage V_IN rail
JP3 V_IN to +5V OPEN Connects autopilot input voltage V_IN rail to autopilot +5V rail, bypassing onboard 5V supply


UART1 VCC Configuration
Jumper Bus Connection Default Description
JP6 UART1_VCC to V_IN OPEN Connects UART1 connector VCC to autopilot input voltage V_IN rail
JP7 UART1_VCC to +3V3 CLOSED Connects UART1 connector VCC to autopilot +3V3 rail

WARNING: DO NOT CLOSE BOTH JP6 AND JP7 SIMULTANEOUSLY!!!


UART2 VCC Configuration
Jumper Bus Connection Default Description
JP4 UART2_VCC to V_IN OPEN Connects UART2 connector VCC to autopilot input voltage V_IN rail SEE WARNING BELOW
JP5 UART2_VCC to +3V3 CLOSED Connects UART2 connector VCC to autopilot +3V3 rail

WARNING: UART2 RX is NOT 5V TOLERANT. Thus, while possible to connect UART2_VCC to V_IN, DO NOT ATTEMPT THIS. Only use JP5 (the default).

WARNING: DO NOT CLOSE BOTH JP4 AND JP5 SIMULTANEOUSLY!!!


Powering the Board

The 3.3V regulator on Lisa/M is a MIC5209-3.3YM capable of delivering up to 500mA. While it is possible to power this regulator with up to 16V, experience has shown that this regulator can become very hot in operation with high input voltages, resulting in potential thermal shutdown while in flight. Depending on the expected current draw, it is best to power this regulator with a lower voltage. 5V is the perfect choice.

The onboard 5V regulator on Lisa/M is a LP2992, a low-noise, low-dropout linear regulator capable of delivering up to 250mA. This regulator can be bypassed with JP3, connecting the autopilot V_IN bus directly to the autopilot 5V bus if, for example, one is using an external 5V regulated supply.

Upload firmware

Uploading firmware onboard USB is not possible with this boart. The boords need hardware modification to make it possible. A very nice way to upload, a.k.a. flashing new Paparazzi code to the board is to use a JTAG adapter. Less convenient since it takes a special adapter. But this adapter makes it more convenient when testing; one does not need to repower the board to reflash. And flashing via JTag cable is very fast.
