Questions tagged [compute-module-3]

For questions pertaining to the Raspberry Pi computer module 3.

The Raspberry Pi compute module 3 brings the power of the new quad-core ARMv8 processor in the known SODIMM form factor to system integrators. This allows professional customers use Raspbery Pi 3 technology in their own products, increased reliability and is a "drop-in" upgrade from the Compute Module 1.
