I think it works just fine with bash.

I think I'm using a pl2303 at the moment, but I'm sure any other will work as well. What you need to connect is only EC_TX <-> RX, EC_RX <-> TX and GND <-> GND.

I've just soldered dupont cables to my device because I only use it as a dev unit. What I want to implement next in Origami-EC is charger and battery support, but I didn't have enough free time to dive into the implementation of it.
