OreSat Mini Backplane
About the OreSat Mini Backplane PCB
OreSat Mini Backplane is an open source PCB design by oresat, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 116.8 × 31.3 mm, with 33 components from 14 distinct parts.
Other key parts include the 3500 and AMS1117-3.3. By type, the board carries 13 resistors, 8 capacitors, 4 connectors and 2 ICs.

This is the backplane for UMBC's Air Harp 2 sensor, which is going to include a PIRT SWIR sensor using OreSat's CFC system.
Match the DXF outline from Joe, including placement of connectors and the fastener holes. Probably remove solder mask from both sides of those fastener holes just in case. Probably put the external connectors in the upper right hand corner. Use an OreSat 20 pin debug connector on this backplane so we can run USB from the CFC processor to the external connector using the CFC processor's debug connector. External connections Power should come through a 0.2 inch…
