I will design esp32 firmware and pcb schematics

Need working firmware for your ESP32 project or a schematic/PCB to go with it? I build both, from scratch or on top of what you already have.

What I offer:

• ESP32 firmware in C++ (PlatformIO): BLE control, PWM motor/fan control, sensor input handling, OLED displays (I2C/U8g2)
• Schematics and PCB design for your circuit
• Debugging tricky hardware issues boot pin conflicts, PWM quirks, flash corruption, I2C problems
• Clean, well-commented, no-frills code

Simulation available for select projects message me first to confirm it fits.

Whether you're prototyping a hardware idea, need a BLE-controlled device, or a custom PCB from a schematic, I can take it from concept to working hardware.

Before ordering, send me:

1. Your ESP32 board/module
2. What the device should do
3. Firmware only, or firmware + schematic/PCB
4. Any existing code, wiring, or photos

I'll confirm scope and timeline before we start no surprises for either of us.
