http://paparazzi.enac.fr/wiki/Lisa/S Lisa/S Lisa/S is a very small general purpose autopilot. The main goal of creating an autopilot of minimal size and weight, while providing a lot of functionality is achieved: Size: 20mm x 20mm x 5mm (0.787" x 0.787" x 0.197") Weight: 2.8g (0.1oz) Features 72MHz 32bit ARM Cortex M3 MCU with 16KB RAM and 512KB Flash Combined 3 Axis Gyroscope and 3 Axis Accelerometer 3 Axis Magnetometer Barometer (Altimeter) Onboard U-Blox GPS Pads to simply connect a Superbit CYRF RC and telemetry module Switching buck/boost converter allowing wide range of power input making it perfect and stable for operation from a 1S LiPO cell. 2 MOSFET switches connected to PWM output channels 6 PWM (servo) outputs 1 debug UART port 1 CAN interface 1 Bind/Boot tact switch SWD programming/debugging interface Size: 20mm x 20mm x 5mm (0.787" x 0.787" x 0.197") Weight: 2.8g (0.1oz) Pictures So if you are ready to make your tiny plane fly autonomously,you can already order one here.
