Description

There is currently a variant of the firmware for this architecture with which the device boots and the radio initializes, but LittleFS is not working. See #2265.

Should be a very low-power device as it uses the same processor as NRF52 (single-core ARM Cortex-M4) running at lower clock frequency, no Bluetooth, and the radio is integrated on the same chip.

Is it really worth to develop this HW? It only has 256kB flash memory, if it ever works, it will be really limited, considering the that other ARM devices compiles to ~600kB binary file. It may be better to implement a stm32wb5mmg + sx1262 https://www.st.com/en/microcontrollers-microprocessors/stm32wb5mmg.html this will have Bluetooth and 1MB flash, just an idea.

It will be worthwhile as an ultra low-power repeater
