## Parts

- SSD1306 128x32px I2C OLED display [[datasheet](https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf)]

- HX711 breakout board [[datasheet](https://cdn.sparkfun.com/datasheets/Sensors/ForceFlex/hx711_english.pdf)]

- 2x 5KG load cell [[link](https://www.robotshop.com/en/micro-load-cell-5-kg.html)]

- AtTiny85

- 3.3v voltage regulator with associated hardware

  - I bought a few LM2937ET-3.3 linear regulators on DigiKey as they can take the 24v input from my 3D printer power supply.
