Thanks. I've been powering the project through a OKI-78SR switch-mode power supply (currently the input is a benchtop power supply, but eventually the much noisier environment of output of the car's alternator). I'll keep an eye on things and if I get issues again I'll look at improved filtering of the output from the power supply.by jamesd - Serial & I2C Devices
Jim, Thanks for the tips. I shorted out pins 3 and 4 and followed your process, then plugged the board back into the project and it's working again. Do you know what can cause this issue? Is it worth me wiring a switch across those pins so I can short them out when the board is in situ without taking it out (it'll eventually be in the dashboard of my car)? I also noticed that the bv4627.devby jamesd - Serial & I2C Devices
I'm working on a project using an Arduino Micro and a BV4627-B, communicating over i2c. Had everything successfully prototyped on a breadboard, and then successfully made a custom PCB for some of the additional circuitry. Put the BV4627-B aside for a while and worked on the rest of the project in isolation. I've now come to plug the BV4627-B back in and it just seems.... dead.
