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)
