A LoRaWAN node powered by an attiny85V and the RFM95W using a CR2032 coin cell battery. Including a smd button and ISP headers for programming.
Components:
Attiny85v-10SU
RFM95W (868 MHz LoRaWAN module)
10 uF capacitor (1206)
KMR231 tact switch (4.2 x 2.8 mm, height 1.9 mm) OR you could solder something else to the pads, for example the 18010P vibration sensor switch
CR2032 coin cell holder
CR2032 coin cell
Add a wire antenna of length 82 mm to the ant1 connection (monopole). For coding: look at this for a good starting point: https://github.com/ClemensRiederer/TinyLoRa-BME280_v1.1/blob/master/ATtinyLoRa.cpp
TIP: The attiny85v can measure both the Vcc voltages and the temperature without using an extra pin. Link: http://21stdigitalhome.blogspot.com/2014/10/trinket-attiny85-internal-temperature.html
