@dc42 said in Did I just fried the 1LC Toolboard:
@SJI it sounds to me that the 3.3V regulator on the tool board has failed. That regulator powers OUT1, the accelerometer and the analog reference for the ADC. It's possible to replace it using hot air rework equipment. The component reference is U5 and depending on your tool board version the part number is either AP2127K-3.3 or AP7366-W5-7.
Another possibility is that the accelerometer chip has failed and it is shorting out the 3.3V rail.
Cheers. Not having the required tools for smd work, think I'll buy another and have a go later at replacing said 3.3V regulator
