Raspberry Pi is available in a "compute module" format which uses a standard SODIMM pin package... They sell quite a lot of them to commercial clients for use in manufacturing. Close to half of all Pi are used commercially, by some accounts. Stable form-factor, excellent documentation and ability to order new stock of specific models for several years after release make it very popular.
