@srgdamiano Hi Sara, I’m new to the Mayfly and trying to get a handle on the output power as it’s not quite as intuitive as the arduinos I’m used to working with. I’d like to connect a MatixBox MB 7383 ultrasonic sensor requiring a 5v power supply. I see there are both digital and analog grove connectors featuring a power and ground pin with a…[Read more]

There’s a simple example with one of the Max Sonars here:…[Read more]
