The Things Network Nijmegen – LoRaWAN module

Next Tuesday we will meet with the core team of the TTN Nijmegen in a small workshop to get things moving. There are some gateways now in Nijmegen (see the coverage map here), so we can and should get started with prototypes and trying to build the local community!

Preparing for next weeks meeting, I ordered a HopeRF RFM95W module at IdeeTron that is compatible with LoRaWAN. Since the hole spacing is 2 mm, making it incompatible with standard headers and a breadboard, I soldered short wires to each of the pads.

This allows me to plug it into a standard breadboard with a little bit of bending of the “legs”.


Note that – compared to the layout in the data sheet – I soldered it upside-down. This allows me to still read the silk screen labels on each of the connections.
