Great experience working on this project. I needed a custom ESP32 DevKit breakout PCB (relay drivers, I2C header, USB-C power), and the seller delivered exactly what I asked for, clear schematic, full component list, and good communication throughout. Delivered on time and within budget. Would work with again.
