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 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). Except for a GPS unit 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.
NEED TABLES AND DESCRIPTION OF JUMPER CONFIGURATION.
Powering the Board
The 3.3V regulator on Lisa/M is a MIC5209-3.3YM capable of sourcing 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 and likely a crash. Depending on the expected current draw, it is best to power this regulator with a lower voltage (5V has been fine).

R/C Receivers
There is Spektrum parser available already, enabling the direct use of 1 or 2 Spektrum satellite receivers.
Also UART pins can be used as general purpose I/O to be used for PPM input. Additionally PPM encoder can be used to avoid receiver hardware modification.

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 convinient since it tke aspecial adapte. But this adapter makes it more conveniet 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 ver handy with JTAG.

Detailed Hardware Revision History
Changes Between v0.1 and v1.0
- Switched to stm32f105 to be able to use usb and can at the same time
- Added alternative use of the adc lines as led output
- ...
Hardware Change 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: This upgrade will be available through Aspirin v2.0 --Esden 22:54, 5 January 2012 (CET)
- REQ: Replace 7 Pin CAN with molex with something less risky to be inserted in 7 Pin SPI in relation to powering the board via CAN molex.
- REQ: Separate spot for external power if powered via separate battery. Realizing we can via Servo ports by Bridge J1 but still like to measure board voltage then and have a way to add power without mistakenly inject CAN Molex into SPI.
