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.

Hi, I can help design the compact dual BLDC control system using one RC transmitter, including schematic, PCB layout, firmware, PPM signal reading, proportional speed control, direction mapping, and failsafe logic. The best solution is to first review your RC receiver output, BLDC driver input type, motor voltage/current, housing size, battery supply, and required control behavior. I’ll then design a compact controller around STM32, ESP32, RP2040, or AVR, depending on the best fit for size, timing accuracy, and availability. I’m comfortable with embedded firmware, RC PPM/PWM signal decoding, dual motor control, BLDC driver interfacing, proportional throttle mapping, forward/reverse logic, failsafe handling, PCB layout, BOM selection, and compact electronics design. Deliverables will include: * Complete schematic * Compact PCB layout * Gerber files * BOM with available parts * Firmware source code * Compiled binary * RC signal mapping logic * Dual motor speed/direction control * Failsafe implementation * Setup and testing guide * Test routine for motor validation I’ll focus on smooth response, low latency, clean wiring, compact size, and easy reconfiguration. Physical validation/video can be done once prototype hardware is available, or I can provide a clear bench-test procedure for your local setup. Best regards Ankit
