Module power connection #28

The module connector has a single 3.3V pin and a single GND pin. Do we need to have more than one pin? How much current can these contacts handle?

We can add a solder pads to the left and right edges of the main PCB to connect higher current 3.3V and GND to be jumped across with wire. This could be useful for larger modules. However, a larger module what fills the entire four module area would have four 3.3V and four GND connections.

3M 0.1" headers have a current rating of 5 amps. For our header I think we'll be good.
