  • 2 dedicated GPIOs.
  • Serial comms (or 2 additional GPIOs).
  • Pin connectors.
  • Arduino-compatible.
  • PWM, I2C, UART, OneWire.
  • On-board WiFi + printed antenna, 802.11 b/g/n, 360m range.
  • Able to become a wireless access point.
  • Lua and Arduino firmware available.
  • Able to run a web server.
  • Dimensions: 24.75 x 14.5mm.
  • Power: 3.3v. (important!!)
