There are several end-node units planned:
loRa back case for the PinePhone
standalone USB dongle-type end-node adapter
as well as a SPI module (which can also be configured as a USB LoRa dongle)
a LoRa stick powered by a single 18650 battery (using the BL602, and can be fitted with GPS, an low-power OLED panel and additional sensors)
All the end-nodes use the SX1262 chip.
