External power luckfox pico mini
Posted: 2025-01-17 12:26
Hey,
With the Luckfox Pico mini B, I see we don’t have any VSYS pin. So for external power I assume I should use VBUS. Is there anything I need to be worried about/take into account when sending power over VBUS, while also using the usb-c both for host and device mode? For example back power? Currently powering it with 3 AA batteries in series. The goal is just to have a stable power supply, so the Pico can function regardless of being in host or device mode, and thus not rely on power from usb-c
