This board is meant to be placed in a CamdenBoss keyfob (Mfr code:2955-20R-5). It contains an Atmega328p arduino mcu, a RFM69 radiomodule, a RGB multicolor led for notifications and a CR2032 coincell holder.
Idle power consumption is measured to be about 300nA.
Note: the board thickness must be 0.8mm to fit in the case

An ultra-low-power and very small arduino compatible wireless temperature sensor.
Features:
- Very small size: same footprint as the CR2 battery holder by itself.
- A single CR2 lithium cell provides enough power to continuously operate approx 6 to 7 years.
- The wireless range is approx 100 meters (RFM69CW)
- The temperature accuracy is 0.25 degree Celcius. (DS18B20 in 10bit mode)
- Update rate of once every minute
NOTE: This design is only the sensor node. The receiver is a separate project.
The zipfile contains the gerber files and a pdf file with design remarks, full schematic, BOM, assembly diagrams, drill/pcb info and an embedded interactive 3D model view (for the interactive 3D view, use a recent acrobat reader to open the pdf file. Otherwise the last page is just empty)

Breadboard & FTDI friendly RN2483 LoRaWAN breakout. The zipfile contains full schematic, BOM, component layout, assembly information, gerbers, 3D renders.
Main changes from V1.1:
- Fix swapped RX/TX signals
- Board has been build and tested. It is fully functional and production ready
Main changes from V1.0:
- Replaced FTDI connector by female version. Now you can plug your FTDI board directly in the breakout board.
- Add 3D renders
