I’m looking for a very small Arduino type device for a project I’m working on. I’m currently using a Teensy 3.2 but just came across an article about the XIAO. Given it’s small package size I decided to buy one. It should arrive tomorrow.
I want to drive a transistor with one of the io pins. The transistor will ground a mosfet on another device. According to this article (https://web-engineering.info/node/82) the XIAO will only provide or sink about 2 Ma at 3.3v.
Has anyone done this and if so can you recommend a good resistor/transistor combination?
Thanks.
