Good. All these software-only projects need to stop eating up all the pis. Especially when they buy multiple just to basically each be a docker instance. Save them for the people that need the hardware interfaces, not that those people always need a pi either. I'll see people online or otherwise using an entire pi just for acting as a Wi-Fi or uart to GPIO bridge, when a USB device would've worked dramatically better. Literally just an FTDI chip is all they need. Set it to individual IO control, use the library, be done with it. No Linux on a microsd card, no waiting for it to boot, no additional power supply, and a fraction of the price
