The Hardwario LoRa Module embeds the Type ABZ LoRa modem with proprietary firmware from Murata. The proprietary firmware can be replaced with the open firmware developed in this project. This wiki page provides step-by-step instructions for performing the update.
You will need the following:
- A recent version of the lora-modem-abz firmware
- A USB-UART converter with support for 3.3 V levels, e. g., UC00A from Cytron
- A breadboard and a bunch of male-male jumper wires
If you have a USB-UART converter with configurable voltage levels, make sure you have 3.3 V selected. Connect the LoRa Module to the USB-UART converter as shown in the following diagram. There is no need to solder to make the connection. The connector holes on the LoRa module are gold plated. It is sufficient to stick breadboard male jumper wires through and fix them in place for good contact.
