In my application, I would like to have a 3 circuit board arrangement. The bottom board would feed power (3.3V) to the Stamp9G20, then the Stamp9G20 would feed the same power in parallel through its top-side connectors to another circuit board (assuming connectors are installed on both sides). The Stamp9G20 would be in the middle of the 3 board arrangement.

Is this idea acceptable assuming the topside board stays within the DC current ratings of the Hirose connector pins?

Thanks.
