Re: [beagleboard] How to connect external power supply to BeagleBone AI?
Looking at the A1 schematic Connect external 5V, + to P9.5 and P9.6 and - to P.9.1 and P9.2. Diodes protect from connecting both cape and USB type C at the same time. P9.1 P9.2 GND P9.3 P9.4 VDD_3V3 output to Cape P9.5 P9.6 VDD_CAPE_5V input to BBAI P9.7 P9.8 VDD_5V output to Cape There is a diode from VDD_CAPE_5V to VDD_5V There is a MOSFET over-voltage breaker from TypeC_VBUS to VDD_TYPE C; and diode from VDD_TYPE C to VDD_5V On Wednesday, 26 August 2020 at 18:57:46 UTC+1 hel...@deepsoft.com wrote: > At Wed, 26 Aug 2020 01:36:02 -0700 (PDT) beagl...@googlegroups.com wrote: > > > > > Hello, > > > > With BeagleBone AI... > > is it possible to use external power supply instead of powering from USB? > > > > I would want to use it for a mobile application (Battery or LiPo).

On both the BeagleBoneBlack and PocketBeagle, there is a 5V supply pin -- P9-7 and P9-8 on the BeagleBoneBlack and P1-1 on the PocketBeagle, which can be connected to a 5V supply. > 2.

[beagleboard] How to connect external power supply to BeagleBone AI?
Hello, With BeagleBone AI... is it possible to use external power supply instead of powering from USB? I would want to use it for a mobile application (Battery or LiPo). USB should be connected just for debug or update purposes. 1. If it possible at all to use external power supply? There is no connector on the board 2. If possible, is it possible to use USB, while external power supply is connected? Or would this cause a damage?
