Would anyone be interested in an expansion card that would allow Meshastic based LoRa communication?
Originally wanted to built an Ethernet expansion board but the CM4 pins for this are not mapped to the DIMM interface, so this seems like the next best thing?
Expansion slot is just a breakout for USB and a few other things. USB to Ethernet would be a simple card to design.
Is the source for Meshtastic available ? I’m interested in it too - but my approach has been to use ESP32 Lora approach via UTP or TCP/IP…
Yes it is, go to the meshtastic site link to github there.
To be honest a Lillygo LORA board is probably small enough to slot straight in and power up and be controlled via USB.
Other software option using same hardware is Rnode, go to unsigned.io
Meshtastic off grid messaging is really interesting
I’m a ham radio guy and an auxiliary communication enthusiast - Lora has real promise when used in mesh network
Exactly, might as well just use a USB dongle if the included controller isn’t connected.
I’m looking to put a RAK4630 or RAK4631 on an expansion board, as you said, hooked up and powered by USB most likely as this should allow serial communication with Meshtastic and the board.
Potentially a GPS module too but I’ll start without.
Hadn’t heard about that project, I’ll be sure to check it out.
I am designing such a board. Have schematic already, was about to post it here tomorrow.
Fantastic! Well you are a couple of steps ahead of me, I would love to contribute if you’re willing to open source the project as I was planning too!
Rnoide!!! Unsigned.io… crazy!!!
I’m definitely interested in this. I was considering making one myself. Not for meshtastic, but for provisioning LoRa devices in the field.
I like the idea, someone posted a design they are working on. You can find it here: [extension] LoRa + GPS board
