We are developed low cost controller named F4BY.
Maxim Strinzha - Programmer
Sergey Lipnickiy - hardware designer and programmer
Alexey Kozin - dedicated to the popularization and promotion, technical support.
APM2 classic sensors set + STM32F407 + sd card + fram
one board , two layers, 50*50mm size
We did software HAL layer and tested it with firmware ARDUCOPTER 3.3.2 and Arduplane 3.4.
Hardware and software has been tested in a test flights, everything is fine.
We would like to integrate the project into a common repository Diydrones.
The current software version is here https://github.com/swift-flyer
we are ready to provide open hardware circuit board in case it is needed.
I wonder whether such integration Diydrones and what you need from our side for this integration?
