Custom ESP32 IoT PCB Design -- 2
Budget: $30 – $250 USD
I’m building a small-footprint PCB around the ESP32 that will serve as the core of several IoT devices. The board must expose reliable Wi-Fi, Bluetooth, and flexible sensor headers so it can drop straight into prototypes and low-volume production runs.
Here is the scope I have in mind:
• Schematic capture for the ESP32 module with stable power-management, antenna clearance, and USB-to-UART programming interface.
• PCB layout (2-layer is fine if performance allows) that remains within 50 × 50 mm, ready for standard SMT assembly.
• Breakouts or onboard footprints for common environmental sensors; I haven’t finalised the exact parts, so leave room on I²C and a couple of ADC/GPIO lines for temperature, humidity or motion modules.
• Production files: Gerbers, drill, pick-and-place, and a clean BOM with part numbers available from JLCPCB/LCSC or a similarly priced house.
• Brief bring-up guide so I can flash and test Wi-Fi/BLE as soon as boards arrive.
Feel free to work in KiCad, Altium, or Eagle—whatever gets me manufacturable files fastest. If you have suggestions on antenna tuning, component substitutions, or clever ways to simplify assembly, I’m all ears. Looking forward to collaborating and getting this board spinning soon.
