A custom 2-layer PCB that ties the ESP32, sensors, and power into one solder-friendly board. Download the full Gerber + drill set below and order it from any fab — JLCPCB runs about $2 for five boards.
Don't want to deal with a fab house? Buy an assembled board for $5 in the Shop.
Rendered straight from the Gerber data: white silkscreen on top, copper traces front and back, and the FR-4 substrate in between. The back copper is one big ground pour for clean sensor readings.
The full circuit — ESP32, HX711 + load cell, MPU-6050, AS5600 encoder, and battery power.
Everything a fab house needs. Upload the zip as-is to JLCPCB or PCBWay — and if you want the board assembled for you, the BOM and CPL files let their assembly service place every part.
