# 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
  - Comunicate in Wiegand, RS485 or 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
  - -40C° +60C° 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.
