The PWR module is exactly what it pretends to be. Based on a small SMD board that turns the 5 Volts of your USB charger or powerbank into the +12 and -12 Volt. Which is needed for Eurorack. It is enough to run the TEDDY Case with the TEDDY Modules, we’ve tried it and it works. Output current goes up to about 250 mA on each rail though some makers tell you it’s 700 mA on +12 Volt and 150 mA on -12 Volt. So no, it’s not something extremely heavy, but it’s nice, cheap and always handy. For example to power that one new module before putting it in your rack. Experiment on the function before giving it its perfect spot.

The module has a 16 pin boxed header, an on/off switch, some things to stabilize possible noise and LED’s. And that’s it, nothing more, nothing less.
