Hi ALL

We are developed low cost controller named F4BY.

project members
Maxim Strinzha - Programmer
Sergey Lipnickiy - hardware designer and programmer
Alexey Kozin - dedicated to the popularization and promotion,  technical support.

Hardware details

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?

interfaces F4BY:

5 USART (one inverted)

1 SPI (free hardware port)

2 I2C (external i2c1 - full access, internal i2c2 not available to the user)

1 CAN

4 external ADC input

2 internal ADC

3 GPIO pins available

8 PWM outputs

8 input-output PWM (supported input PPM, PPM-Summ, DSM, S-BUS)

1 access to the beeper (PWM)

1 input sonar connection (either a timer or interrupt 9-5)

    Love It. ( I'm a stm32 fanboy :) ) 

    Is there a spec, such as number and type of ports (USART, I2C, CAN, SPI Servo outputs SBUS options, ADC) etc etc.

    I would hope that a schematic will be made available if you want it to have official support. Closed source hardware would make it a non-starter for me. Would be nonsensical surely

    Do you have any further details on the hardware? For example what "classic sensors" did you use? Also, do you have a price? How can it be purchased?
    • we plan to set the value for the end user $ 65, but are ready to send developer samples for cheaper then IC set cost

      • I would like to test one. Can you tell me the way to get it?

        • send me email kozin@mail.ru . 
          I will send in response to your mail paypal invoice

    To get it integrated integrated into upstream, you must rebase your branch on to master then create a new pull request and we will evaluate it and give you feedback. Once we are happy with it we will merge it in. https://github.com/ArduPilot/ardupilot/pulls

    Also, for new hardware we require that you provide a person who is the maintainer for when people have questions about it we can forward them to you.
