Arduino (atmega328p) based RFM69 to Wifi MQTT bridge (ESP12-F)

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

Very tiny Arduino based wireless board for remote-controlling an electrical wall outlet. (Atmega328p-mu, RFM69 radio module, 0402 sized components).

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
