Hello MangOH forum,
I’m working on a PoC with the MangOH Red and have a 3.3V power supply. I see the MangOH Red can be powered thru two 5V USB interfaces or thru the Li-battery charging interface. However, the battery charging interface only seems to power on the module (RC7611) between 3.3 and 3.7V, but doesn’t actually allow for network registration to occur unless the voltage is above 3.68V (at least from my bench testing). The module appears to be in a reboot cycle if the battery voltage is not sufficient.
So, is there a way to power the MangOH Red off of a 3.3V (3A) power supply?
Please let me know.
