Dual BLDC Control via RC

Descripción de la oferta
I have a prototype that has to drive two independent BLDC motor drivers from a single hobby-grade RC transmitter. Both motors must respond to the same handset, with full speed and direction control on each channel. The throttle stick should give smooth, variable speed rather than stepping through fixed levels, and the entire solution needs to stay as compact as possible so it can fit inside a small housing I already have. Here is what I need from you: • Hardware: a complete schematic and compact PCB that takes the receiver’s PPM and feeds two BLDC driver stages. Component selection should balance size, thermal performance, and ready availability. • Firmware: clean, well-documented code that reads the RC signals, maps them to forward/reverse and proportional duty cycle for each BLDC, includes failsafe, and is easy to reconfigure. I am open to STM32, ESP32, RP2040, AVR, or any controller you are comfortable with as long as it remains small. • Validation: a short test report or video proving that both motors track the remote smoothly in both directions, with no jitter or noticeable latency. • Files: complete source code, compiled binaries, PCB Gerbers, BoM, and a brief setup guide so I can reproduce your results. If this compact dual-motor control challenge fits your skill set, let’s talk about timelines and any extra details you need.
