Sony's technology centre in Pencoed has secured a multi-million pound manufacturing deal creating mini-computers.
The Japanese company says it expects to create up to 30 new jobs to meet the demand. Around 450 people are already employed at the plant near Bridgend.
The Raspberry Pi is a computer the size of a credit card, designed to stimulate young people’s interest in computer programming and electronics.
300,000 units will be built as part of the deal.
The Raspberry Pi went on sale in February, but the designers found themselves having to outsource its production to China in order to keep costs down.
