The main features of the pcb are:

  • Small dimensions: 55 x 55 mm
  • Socket for NRF24L01 radio module with dedicated capacitor
  • MYSX connector v.2.6
  • Radio traffic LED
  • Multiple and flexible power options (5-23V)
  • Support for a photoresistor to measure the light level
  • Buzzer (beeper)
  • Support for DHT22 temperature and humidity sensor
  • 4 channel RGBW LED controller
  • Dedicated 3.3V voltage regulator to power the radio module
  • Additional PIN to power external devices
  • Support for ATSHA204 IC
  • Support for DC Barrel Jack
  • Mounting hole for a M2.5 screw
