Hello... My name is Carlos... I'm a Computer Science Engineer with extensive experience in digital electronics... I've worked with Microchip PICs, Arduino, Teensy and many other microcontrollers...as well as many sensors and actuators...
I think I can help you with your project because I've worked many radio controlled gear (RC) in which data transmission is a very important factor... as well as your project needs..
Also I've made some circuit design, production and testing, so I can deliver a complete supported platform based on standard hardware, but specifically designed to your needs.
Let me know.
Regards,
Carlos.
