Mini backplane
About the Mini backplane PCB
Mini backplane is an open source PCB design by mnarigon, published on GitHub under the MIT license. It is a 2-layer board measuring 196.9 × 82.6 mm, with 10 components from 5 distinct parts.
By type, the board carries 7 connectors and 3 jumpers.
From the project
A 4-slot S-100 bus passive backplane
This is a 4-slot S-100 bus mini-backplane with power supply chassis.
It is intended for someone interested in building and running S-100 bus cards, possibly as a first project or for use on a test bench.
Features: - 4 slots. - Chassis is designed for three Mean Well switching power supplies to provide 8V, 16V, and -16V in one unit. The maximum 8V current is 10 amps. - Jumpers to ground for S-100 pins 20, 53, and 70. Some pre-IEEE-696 cards use these pins for signals where IEEE-696 defines these pins as grounds. - Connector for a reset switch.
