The seeed Studio XIAO SAMD21 - Arduino Microcontroller - SAMD21 Cortex M0+ as 5V pin which I need to use but no BLE.
Is there a BLE XIAO version with 5V pin or any idea how to connect 5V to a BLE XIAO version?
There is a pin marked 5V on the Xiao BLE, I’ve seen a couple of projects write ups (Not official Seeed) that mention the 5V is available if powered via the USB. I don’t know what limitations might apply for the pass through, max current, etc.
I’ve seen mention the GPIO pins must be limited to 3.3.
