Roland designed a compact ESP32-based custom PCB for my project and worked through several schematic and layout revisions with me. He was responsive, professional, and provided the complete editable design and manufacturing package. A few BOM/CPL details required correction during the JLCPCB upload,...

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.

Communication was clear from the start as usual, we discussed exactly what I needed before he sent a custom offer, so there were no surprises. He delivered a clean schematic...
