We encountered a problem, hope to get some insights into solutions:
Tried to boost a lithium battery from 3.7v to 5.0v to work for bela mini. When testing the voltage of the boosted battery through an ammeter, it flashed a value around 9v, and then dropped and stabilized at 5v . We thought it was successful and connected it with the bela mini. One problem that the pin of battery was inserted into a Vout pin the first time. And then, after the correct insertion, the Bela mini wasn't powered on. We connected it to the computer and the blue LED flashed briefly once. Was it died?
Thanks in advance for any help.
