PoE powered Node on Ethernet voor de deur van de space zelf.
Inhoud
Electronics
Todo: Add schematic / POESP pinout
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 a.k.a. "Grote Schakelaar"
- socket for A4988-type stepper motor driver
- 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 a.k.a. "Grote Schakelaar". High when switch is off (or wire broken). Goes low when the switch is on.
The pinning on the RFID reader is (most probably):
