@nebrius hey, does Raspi-io support software serial/bit banging? I'm struggling to get two breakout boards (Ultimate GPS and BNO055) working when they both require UART (BNO055 supports I2C but I can't use it because of clock-stretching issue on RaspPi). I'm new to this and in way over my head. I saw a node library called pigpio that does this type of GPIO -> UART kinda conversion, but then I also saw that pigpio is used in raspi-io, so I'm guessing it's supported(maybe?).
