Lisa

Lisa ( the Lost Illusions Serendipitous Autopilot) is a new range of autopilots based on STM32 microcontrollers ( CortexM3@72Mhz ) designed to run Paparazzi. There's no such thing as a perfect autopilot, only autopilots adapted to a particular purpose. This is the reason why Lisa comes in different flavors for different usages.

The first members of the family are:

• Lisa/L, a design where the STM32 is associated to a gumstix Overo.
• Lisa/M, a design focusing on cost and simplicity.

Lisa/L

Description

Lisa/L is a dual processor board autopilot designed to allow the possibility of using Linux for Paparazzi airborne code.

Documentation

The documentation about Lisa/L has been split in two: You can have a look at the User/LisaL user manual or the Dev/LisaL developer manual or look at pictures on the LisaL_Gallery gallery page.

Lisa/M

Description

Lisa/M is a 50*25mm single processor board, with 7 full size servo connectors. This board is about the size of a conventional RC receiver and features a footprint for an aspirin IMU and an affordable barometer. Intended usages range from a CAN servo driver to a full blown autopilot or a flybarless heli controller.

Documentation

Lisa/M is only at the stage of prototype. Documentation will follow as soon as the board reaches production stage.

Lisa/S

Lisa/S is only a project at the moment. The focus for this design is size, weight and power consumption. The intent is to produce an autopilot suited for the smallest airframes. For now just a CAD rendering to wet your appetite.

Other Additional Boards

SWITCH BOARD

It will be very useful to have a board with 4 MOSFET switches communicating with Lisa autopilot with CAN. With this board will be possible to turn on & off de power for onboard equipment like video cameras, video transmitters, etc.

I think a Tension of 5V - 12V and current of 1A máximum should be sufficient to almost onboard equipment.

Anyone interested in develop this board?
