Wiring Details
- 1.USB power cable to supply 5V power to the step up converter (standard USB micro cable can be cut in half and the
USB type Apart used for this). - 2.USB micro cable to provide 5V power to the Raspberry Pi Zero (second half of the cable cut in half in step 1).
- 3.If you are using a step up transformer, that can supply a variable amount of voltage, make sure it is properly set to 12V with a multi meter (by twisting and adjusting the tiny screw).
- 4.The output of the step up transformer (set to 12V) supplies to coin acceptor with 12V power.
- 5.The ground connection of the step up transformer must also be connected to a ground pin of the Raspberry Pi Zero (see pin out details below
CoinAcc(G)). - 6.Attach the camera to the CSI camera port of the Raspberry Pi.
- 7.To detect button presses, pins
BCM5and3v3 power(see pinout below) need to be connected to the button (normally closed connection (NC)). - 8.(Optional)
BCM13andGround(see pinout below) can be used, if your button has an LED inside, that can be controlled by the ATM software. - 9.Cables that connect the Papirus E-Ink display to the Raspberry Pi Zero (see pinout below).
This pinout is only applicable if you use the "PaPiRus Zero - ePaper / eInk Screen". For other eInk displays please refer to its manual or ask in the Telegram group for help:
