Wireless "charging" module.

I have a Seeedstudio wireless charging module.

12VDC in and 5VDC out.

As the output is not grounded could I connect two units in series to give 10V output?

I'm thinking of having the 12VDC inputs in parallel.

Yes.

You might be better off with a voltage boostor on the output though (depending on how many amps you need).

Thanks, I’ll give it a try and have a look into voltage boosters.

I’m aiming to get the current down to <100mA but the test unit might be closer to 500mA.

It is OEM by ElecFreaks ?

ElecFreaks is an open hardware facilitation company based in Shenzhen, China.

I voted anything is open, The output can be customized to 3.3V 5V 9V 12V etc.
