It’s fair to say that right now is probably the worst possible time you could choose to design a new piece of hardware. Of course the reality is that, even in the middle of a parts shortage that’s driving the cost of many components through the roof (if you can even find them), we can’t just stop building new devices. In practice, that means you’ll need to be a bit more flexible when embarking on a new design — it’s like the Stones said: “You can’t always get what you want / But if you try sometime you’ll find / You get what you need”
For [Ryan Walmsley], that meant basing his new outdoor LoRa gateway on the ubiquitous Raspberry Pi was a non-starter. So what could he use in its place? The software situation for the Nano Pi Duo looked pretty poor, and while the Onion Omega 2+ was initially compelling, a bug in the hardware SPI seemed to take it out of the running. But after more research, he found there was a software implementation that would fit the bill.
