From the project

Repo for the OreSat +/-Z end cards (Card #1 and #20)

The ESI -Z End Card fits in the very "bottom" slot (Slot #3?) in the OreSat 3U backaplane. It's special because it hosts whatever antenna is on the -Z face of the satellite, which in this case is the ESI POD antenna. The -Z End Card:

- Connects to the backplane with a main connector and three RF SMPM connectors - Connects four -Z solar modules to the backplane - Routes an SMPM connector to a U.FL connector to jump up to the -Z End Cap's L1 band GPS patch antenna - Has an OPD circuit to control: - Deploying the dipole antenna - Switching C3-UART to any of the -Z solar modules
