DMX Core BB-1 Full Schematic License


Availability: 10 in stock


The DMX Core BB-1 is a baseboard or carrier board designed for the Raspberry Pi CM4 module. It comes with a set of desired features and is intended as a starting point for your own custom CM4 baseboard. You will receive the complete schematic in KiCad format, PCB layout and instructions to place a PCB assembly order directly with a PCB fab house like JLCPCB. You will receive one prototype board directly from us as well (not including CM4).

This purchase is for a license to use the schematic in any of your own designs, as many as you wish, no restrictions. You will receive updates to the schematic for one year after purchase (in the same model line).
