Does anyone know how much power is available at the USB A port on the Beryl AX? I'm trying to build a cellular modem to use with it and it would need to be powered by that USB port.

Hi,

That’s it? Doesn’t the M2 dev board require at least 12V/1.5A?

This is straight from the M2 datasheet… “ \* **Power Input:** DC, 12V/1.5A”

Yep, the M2 dev board needs external power supply, and it has a power interface
