ATTiny Sensor Node (ATTNode)
Overview
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)
