DCT Electronic HX711 board plugged into P5

Building a scale using the DCT Electronic HX711 board is as easy as Pi!

  1. Order the board from ebay
  2. Download the software from gitHub
  3. Solder headers in P5 and DCT board
  4. Solder the load cells to the DCT board.
  5. Change the GPIO pins from 30 and 31 to 28 and 30 in hx711.c This way they are all on one side of P5:
#define CLOCK_PIN       30
#define DATA_PIN        28
P5-1 +5
P5-3 GPIO28
P5-5 GPIO30
P5-7 Ground

Comes with two sets of headers, straight and right angle.

need a female header 1x4

Just need load cells and calibration
