I have 10 micro:bits in my classroom. The Hummingbird extension is added. Some of the hummingbird boards are not working. I know because I have connected different hummingbirds to the same Micro:bit and servos. Does anyone else have this issue? Is there a way to update the firmware on the hummingbird breakout board?
