# Pony-Card-WRS4i2o

Pony-Card-WRS4i2o is a Wiegand/RS485 capable card for access controle powered by PoE

# Main feature 
  - Powered by PoE or 12V/2A input
  - Power sercurity device like badge reader in 12V/0.5A
  - Wiegand or RS485 input selectable by switch
  - In Wiegand mode, 1 digital output (e.g for drive 5V Led or buzzer from badge reader)   
  - 4 digital input (3V to 24V)
  - Drive 2 output NO/NC relay (230V/5A Max)
  - Can run on WiFi and/or Ethernet (e.g for failover)
  - Ready to Home assistant with EspHOME (Sample config avaliable)
  - Ready to MQTT with Tasmota (Base firmware avaliable)
  - -20C° +60C° running continous capability
  - Fit in DIN PLC Box like [this](https://fr.aliexpress.com/i/1005004933689728.html)
  - Dimention : 92.4mm X 87.5

# Misc
R49 was unpopulated resistance, because it's just for very old PoE device, support only type 1 PoE and this type need permanante 10mA current drain. But this produce 0.5w of heat and in certain condition make overhead the board, please populate only if your PoE injector dont work without an be careful of probaly over heating in +50C° environement.
