The Raspberry foundation has updated their Compute Module with a new version which in essence is a Raspberry Pi in a flexible form factor. Raspberry says that the new Compute Module aims at providing a cost effective way for industries to build customized products like a LED panel. The new module is based on Pi 3 and thus it also touts a huge performance gain as opposed to its predecessor which was based on the first generation of Pi.
The innards include BCM2837 processor which can be clocked up to 1.2GHz and will come with 1GB of RAM. Statistically, the new Compute model has a doubled up RAM and 10x CPU performance as opposed to the original CM 1. Since its based on Pi 2, the chip can run Windows 10 IoT core and will also allow for an IoT project to be ported from a Pi 3 to a custom CM3.
It seems like Raspberry has also addressed one of the biggest bottlenecks in the CM1, the storage. While CM1 came with a fixed 4GB storage the CM 3 comes in two variants, the lite model will allow users to add their own SD cards while the other variant will retain the 4GB eMMC. Raspberry expects the one with expandable memory to be more popular since most of the users don’t like the idea of being locked to a certain storage space.
Also, the CM 1 and the CM 3 can be used on the same boards i.e as drop-in replacements since both of them are pin compatible. Also since the CPU on the CM 3 can pull more current from the power supply it is also expected to generate more heat in certain full load situations. The Compute Module 3 and CM3 Lite are priced at $30 and $25 while the CM1 will still continue selling at $25. Also, Raspberry has launched an updated IO breakout board (CM103) which is designed to accept all the three models.
