A Minimalistic Sensor Node for use on TheThingsNetwork with the following Features:

  • Small Size, only 47x36mm (v1) / 34x26mm (v2)
  • Based on widely available Atmel ATTiny84 MCU and RFM95W LoRa-module
  • 6 free GPIO-Pins from the ATTiny + Power to connect sensors on a 2.54mm pitch header
  • Optional on-board LED for status signaling
  • Powered by a single CR2032 lithium battery
  • Long battery runtime using the ATTinys deep sleep mode
  • Integrated 6-Pin programming header
  • Small component count
  • Possibility for edge-mount SMA connector or u.fl SMD connector (v2)
