Third party

List of third party products made using the CM3-Home board

CM3-Home for the OEM market

The CM3-Home board is an OEM electronic parts mainly suitable for B2B market and instead of end-users looking for a ready-to-use Home Automation system.

We do not provide any ready-to-use microSDs or support to install software on this mother board but just the basic info about the small differences between the standard Raspberry Pi 3 and the CM3-Home implementation to understand how to use it with the standard Raspbian distributions.

The typical customers for this board are:

  • System Integrators that want to create their own professional Home Automation solution based on Raspberry Pi 3 architecture
  • Makers that want to create their own Home Automation software on a reliable platform
  • Resellers that want to sell the board as is or arrange a kit with CM3-Home, Raspberry module, microSD, case, power supply, etc to maximize their own gains

As like as any other Acme Systems product the CM3-Home board is provided inside a simple antistatic bag without any printed paper or manuals.
