Anyone who can help,

Can anyone help me identify the correct pins on the Teensy 4.1 to which a battery should be connected for the RTC to continue to function?
There's no indication on the pin-out diagram.

Many thanks,

Allen
 
Hi Manitou,

Many thanks for your quick response, and I have looked through that posting, but cannot see any pins labelled 'VBat'.

Is there something that I should be looking for?

I appreciate your help,

Best wishes,

Allen
 
The holes next to the micro-SD card reader, are in the same order as the Teensy 4.0, but in a different location. Going from top to bottom on the above picture of the back side, the pins are:
• Pin 38 on the outer row
• On/off
• Program
• Ground
• 3.3v
Vbat
• Pin 27 on the outer row

They are identical in order to the T_4.0, just shifted over to accommodate the parts and match the T_3.6 form factor. As @Saibot notes they are called out lower in the text linked by @Manitou.
