Hello, due to the global shortage of Raspberry PIs, do you support or recommend any alternatives for running RAK2245, RAK2287 etc?
There is a SBC called “Libre” which seems to be the exact form factor and pinouts as RPi, but it’s based on the Allwinner and other SoC. (see https://libre.computer/). If these units run debian or ubuntu, would the RAK drivers work as long as they are pin-compatible with RPi?
Unofficially I’ve used these modules on other hosts.
The big issues would be that the host needs to support SPI, (and if you want a GPS to work also have a UART or I2C channel), that you’ll need to do some degree of custom software work, and that the system be preferably more robust against unexpected power loss than a pi’s consumer grade SD card(!)
If you only need a few systems this is fairly easy, but a challenge if you have an ongoing need is that a lot of these platforms tend to get end-of-lifed just as you finally get everything figured out - that’s especially true of the the whatever-pi platforms based on Allwinner tablet chips, as that line of SoC’s is contanstantly marching forwards rather than staying in one place the way a meant-for-embedded SoC would.
