There's a stepperdriver, a RFID reader, a power output to "grote Schakelaar" and an input for the door open/closed switch.
+
On the motherboard there are:
 +
* resistor between "Set V++" and GND, setting the voltage output for the stepper motor ("Vmot" terminal of A4988) to 12V
 +
* transistor for amplifying the pulses on GPIO16 for the buzzer
 +
* ''pull-up resistor for MS1, ensuring the motor is making half-steps (?)''
 +
* R-C circuit for the [[Project Grote Schakelaar|a.k.a. "Project Grote Schakelaar"]]
 +
* socket for A4988-type stepper motor driver
 +
* header for the POESP board
 +
* 8-pin RFID reader connector (brown/red pin is rightmost)
 +
* 4-screw terminal for the stepper motor
 +
* 2-screw terminal for powering auxillary devices (not connected)
 +
* 2-pin terminal for the buzzer, which sounds when RFID is read successfully
 +
* 2-pin terminal for the [[Project Grote Schakelaar|a.k.a. "Project Grote Schakelaar"]]. High when switch is off (or wire broken). Goes low when the switch is on.
  
−
The door open/closed switch is wired to GPIO34. High when door is closed (or wire broken). Goes low when door is open (and everything functions).
