These are helium miners. As helium is no longer a thing, they can be nicely repurposed.

In the inside you'll find a raspberry pi(!), a wifi- and a bluetooth dongle.

  • Pi CM3 Lite compute module, with 32GB(?) eMMC module in microSD slot
  • power supply from PoE or "9-16V DC @ 15W" barrel jack
  • lorawan module (useless for meshcore afaik), with ipex/U.FL plug for outdoor antenna
  • BT and wifi modules on internal usb hub
  • Ethernet port on mainboard (with PoE support)
  • 3 minipcie slots (once the lorawan module is removed) - one wired for USB, two for SPI. The USB-wired one also has a SIM card slot.

Unfortunately the annotations for WiFi and BT are swapped on the following image:

The SD-card can be mounted on a regular linux system:
