I have a project which I’d like to power with one LiPo cell (3.7V-4.2V depending on the charge level). I was wondering if I could power Sirius RTK GNSS Rover F9P directly from the LiPo through 5V IN?
It’s clearly below the rated 5.0V but could work if 5V IN is just regulated down to 3.3V for everything in the module. Or is there something in the module which needs 5.0V? The module would be further connected to uC with 3.3V I/O (5.0V tolerant) so UART1 TX/RX communication should be ok.
