Raspberry Pi Compute Module 3 I/O Board CM3 I/O 開發板
Compute Module IO Board V3
The Compute Module IO Board V3 is a development kit for those who wish to make use of the Raspberry Pi in a more flexible form factor, intended for industrial applications. The IO Board V3 is made for developing with CM3, CM3L, and CM1.
The Compute Module contains the guts of a Raspberry Pi 3 (the BCM2837 processor and 1GB RAM). The accompanying IO Board is a simple, open-source breakout board that you can plug a Compute Module into. The board hosts 120 GPIO pins, an HDMI port, a USB port, two camera ports, and two display ports. Designing the Module into a custom system should be relatively straightforward as we’ve put all the tricky bits onto the Module itself, and you have the freedom to add extra components and place parts exactly where your product needs them.
The Compute Module IO Board V3 is designed for use with the Raspberry Pi Compute Modules:
• CM1 (Raspberry Pi Compute Module)
• CM3 (Raspberry Pi Compute Module 3)
• CM3L (Raspberry Pi Compute Module 3 Lite)
This I/O breakout board plugs onto the Compute Module to provide access to various ports that you would see on the traditional Raspberry Pi boards.
Why do I need one?
You can use the CM3 I/O board as an adapter to get your Compute Module set up. The Compute Modules themselves do not have connectors on board, they are designed to be embedded into applications.
That’s where the CM3 I/O board comes in handy. It has all of the things that are harder to add, all on the board already. There is also the ability to add additional components if and when you need them.
