From the project
A backplane for the 1802 Mini as an alternative to the stacking physical format. Incorporates power, reset, and input buttons,.
This is a backplane for the 1802/Mini system. It supports the following features:
Seven slots using 1x39 single-row header sockets Power, reset, and, and input pushbuttons Power input via mini-USB or 2.1mm barrel jack USB pass-through header, can also be used for power Boards can be coupled end-to-end to make larger backplanes PCB can also be assembled as a slot extender card * Optional pull-up resistors for TPA, TPB, and CLOCK
