+The Compute Module is a Raspberry Pi in a more flexible form factor, intended for industrial application.
+
+The Compute Module contains the guts of a Raspberry Pi (the BCM2835 processor and 512MB RAM) as well as a 4GB eMMC Flash device (which is the equivalent of the SD card in the Pi). This is all integrated on to a small 67.6x30mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory). The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2835 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the Module itself.
+
+The Compute Module is available for purchase in single units, or in batches of hundreds or thousands. To get started designing a PCB to use the module, we provide an open-source breakout board with a single module in an affordable development kit.
+
+The original Compute Module was replaced by CM3 in January 2017 but is compatible with the new Compute Module IO Board V3, and remains available for sale.

+The Compute Module 3 contains the guts of a Raspberry Pi 3 (the BCM2837 processor and 1GB RAM) as well as an optional 4GB eMMC Flash device (which is the equivalent of the SD card in the Pi). The Pi 3 has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU.

+The Compute Module is a Raspberry Pi in a more flexible form factor, intended for industrial application. CM3+ (Compute Module 3+) is the Raspberry Pi 3 B+-based revision of the original Compute Module. The big update to the CM3+ compared to the CM3 series is more eMMC Flash memory and the new heat spreader on the main processor which will let it run at full speed much faster without overheating.
+
+The Compute Module contains the guts of a Raspberry Pi 3 B+ (the BCM2837B0 processor and 1GB RAM) as well as a 8GB eMMC Flash device (which is the equivalent of the SD card in the Pi). The Pi 3 B+ has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU. This is all integrated on to a small 67.6mm x 31.1mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory).
+
+The Flash memory is connected directly to the processor on the board, but the remaining processor interfaces are available to the user via the connector pins. You get the full flexibility of the BCM2837B0 SoC (which means that many more GPIOs and interfaces are available as compared to the Raspberry Pi), and designing the Module into a custom system should be relatively straightforward as the Pi Foundation has put all the tricky bits onto the Module itself.

+
+The Compute Module contains the guts of a Raspberry Pi 3 B+ (the BCM2837B0 processor and 1GB RAM). The Lite version does not come with on-module eMMC flash found on the Compute Module 3+. It also does not contain the WiFi/Bluetooth chipset that comes with the Pi 3 B+. 
+
+The Pi 3 B+ has a processor speed of 1.2GHz and runs at roughly 10 times the speed of the Pi 1 due to its quad-core CPU. This is all integrated on to a small 67.6mm x 31.1mm board which fits into a standard DDR2 SODIMM connector (the same type of connector as used for laptop memory).
+
+This version is intended for users who will be adding and using an SD card interface on the interface board.
