I have to power multiple boards for a custom project. 16 boards. Each board draws 43ma aprox. so total draw is 688ma.@ +/-17v.
My idea is to use IDC cable to power all boards to provide gnd return and rails. So it ocuured to me to use the same scheme as modular synths are using. A 10 pin IDC connector, with the central 6 pins for GND and the 4 side pins for +/- 17V. My question is if this is enough GND regarding return current path to the linear PSU, and noise.
