Hi there,
I am using a board that only has a power output of 3.3v (the Redbear Duo). I want to power the 5v MQ-7 and read the analogue data. Do I need to also purchase a Logic Level Converter, or can I simply power up the MQ-7 with an external 5v power source (ie: an Arduino UNO)?
Thanks in advance, I’m pretty new to this! Let me know if you need more information.
