Dani's Node
A LoRa radio node supplied by Dani. Consists of two boards which can be soldered together directly: An nRF52840 board, in nice!nano / promicro format, and an SX1262 board with two buttons.
Flashing
Flashing can be done by dragging a .uf2 file to the drive that appears on USB connection. However, this did not work for me initially. Bootloader was version 0.6.0. I upgraded this to 0.9.2 and then the latest meshtastic image was recognised and programmed.
Meshtastic
Firmware image is called: “NRF52 Pro-micro DIY”, available on the github releases page.
Power
I have measured when running meshtastic, LEDs disabled, not transmitting.
Supplied on battery terminals:
- 3.32V: 8.7mA
- 4.20V: 7.9mA
3.3V to 3.3V pin on board: 8.6 mA.
Current draw reduces by about 600uA from these numbers when connected to phone by bluetooth, which happened about 35 seconds after power on.
