- Complementary over-current and reverse-voltage protection: the left and right halves of the 1-6-13 are independently protected with Polyfuses (±12V @ 1.1A, +5V @ 0.5A). The PSU connectors are unprotected, so downstream boards are unaffected
- Three sets of indicator LEDs to indicate status of: left side, right side, PSU input.
- Dual PSU Input connectors, mounted in the middle of the board for proper “star” distribution scheme.
