Hello, I would want to resolve the following question, ¿Can I connect the satellite module in his PCB with from USB 2.0 and external power supply on the same time? for example, such as show you the picture attached. It’s possible to do that and the modem can convey packets to Satellite.

Have a good day.

USB 2.0 is _not_ supported for that board; but yes otherwise. See [https://learn.sparkfun.com/tutorials/sp … akout-pins](https://learn.sparkfun.com/tutorials/sparkfun-satellite-transceiver-kit---swarm-m138-hookup-guide/all#breakout-pins) (the description for power circuitry is slightly above) and [https://cdn.sparkfun.com/assets/1/a/7/c/8/Schematic.pdf](https://cdn.sparkfun.com/assets/1/a/7/c/8/Schematic.pdf)

Hello,

Too, Is posible to connect the PCB with the modem to a HUB with external power supply wit ports USB 2.0?

Regards.

Hi,

Yes, that should work. The external power supply will deliver power to the modem - through the “ideal diode” circuit.

Best wishes,

Paul

In this case, Can the device convey data to the satellite and see this information in Swarm Hive?
