#REDIRECT [[Lisa/M v2.0]]
 
If you consider yourself a developer this autopilot board is for you. If you enjoy writing software and consider yourself an early adopter this hardware is for you. Have fun and see you on the paparazzi mailinglist, the wiki and the freenode irc channel

== Features ==
Lisa/M is based on the 64 pins STM32F103RE processor featuring 64k of RAM and 512k of FLASH. All the pins are exposed, providing access to the complete set of the STM32 peripherals.
 
 
== Overview ==
 
* Single [http:// STM32 MCU]
* 8 x Analog input channels 0V - 3.3V (2 channels with optional on-board resistor bridge)
* 1 x 3.3V TTL UART (5V tolerant)
* 7 x PPM outputs
* 1 x R/C receiver PPM frame input
* 1 x [http://en.wikipedia.org/wiki/Serial_Peripheral_Interface SPI] bus
* 1 x [http://en.wikipedia.org/wiki/I2c I<sup>2</sup>C] bus
* 1 x Micro USB (client)
* X 5v / 2.25A switching power supply (input voltage range 6.1v &rarr; 18v)
* X 3.3v / 1A linear regulator
* 3 x status LEDs with attached test point
*  grams (0. oz)
*  x mm (" x ")
* 2 layers PCB design,  components
 
=== Footprint ===
 
This autopilot is the smallest of it's class. The footprint is only 24mm by 40mm. Incorporating everything you need to build the smallest autonomous UAV. It comes with a pressure sensor built in for altitude measurements and a place for mounting the Aspirin IMU directly on board, without increasing the size of the module.
 
=== MCU ===
 
In brief, the STM32 features 3 USARTS, 2 SPI, 2 I2C, 1 CAN, a plethora of timers, ADCs and a generic DMA able to serve all of them. On the board, a number of the communication interfaces are level shifted with user selectable voltage to allow interfacing with all kind of peripherals.
 
=== IMU ===
 
The Lisa/M comes with Aspirin IMU mounted, for easy attitude estimation in the smallest package possible.

== Connect Receivers ==
 
To be able to test your UAS a RC receiver comes in very handy.
 
=== PPM receiver ===
 
A modified RC receiver with full PWM out can be used to control the AP board from the ground.
 
=== Satellite Receiver ===
 
Connecting a 2.4 Spectrum compatible receiver

It is possible to reconfigure the electrical system on Lisa/M using the supply jumpers.
 
* JP1 connects the servo power rail to V_IN rail.
* JP2 connects the battery rail (used by default only for battery voltage measurement) to the V_IN rail.
* JP3 bypasses the +5V voltage regulator and connects V_IN to the +5V rail.
* JP4 connects the +5V rail to the VCC pin on the UART2 connector.
* JP5 connects the +3V3 rail to the VCC pin on the UART2 connector.
* JP6 connects the +5V rail to the VCC pin on the UART1 connector.
* JP7 connects the +3V3 rail to the VCC pin on the UART1 connector.
