we have noticed that the tiny battery connector present on a Nicla Sense board, but also on Portenta H7, makes the battery search a challenging one.
Can anyone recommend a link to a vendor of a ready to use Li-Ion battery compatible with these boards. The only ones found until now are from HiMax/Murata. However they have a reversed wiring position compared to the one Arduino accepts.
- Arduino nicla /h7 require (pin 1: +VBAT, pin2: NTC, pin3: GND)
- commercial cells we were able to find have( pin 1: GND, pin2: NTC, pin3: +VBAT)
we don't want to solder an external battery on alternative pins, nor hack the tiny battery connector.
much appreciated
