Incidentally, the Raspberry Pi Compute Module is indeed "rather unknown", which is a shame. It is amazingly useful and lets you design devices without getting into high-complexity PCBs and BGAs. You can place an SO-DIMM socket on a simple 4-layer board (adventurous types might even go with 2 layers if you don't need USB) and build a computing device that would otherwise be out of reach.
Another added bonus is the built-in flash, which is significantly more reliable than the whole SD card setup (for many reasons). Or the two CSI ports (only one is exposed on the standalone RPi board).
All in all, for anything except prototyping, this is a much better solution than a standalone RPi. In my designs, I found it to be a useful and reliable workhorse.
- domsl 7y agoMay I ask, in case you use Wifi: Which Wifi module do you use for the Compute Module? Because I agree it is a very useful form factor.
- l1k 7y agoThere's a Revolution Pi product coming this year which has WiFi built in (called "Connect Flat", was on display at the SPS fair in November 2019). We used a chip based on Cypress CYW43455, basically the same as on the Raspberry Pi 3B+, to benefit from the existing decent driver support.
- domsl 7y agoI see, thats smart. My question would be how would I start out doing something similar? Because the I was thinking I would just have a look at the rasperry pi 3 b+ schematics (which do not show the Wifi Module, because they are incomplete, so I guess SDIO or UART?). Compare it to the schematics of the compute module, design a board thats connectso the Cypress Wifi Module and use the same drivers used in the rasperry pi 3 b+.
- jwr 7y agoI designed in a WG7831-DELFA WiFi/Bluetooth module, based on TI Wilink8, connected via SDIO.
- jbverschoor 7y agoThat's pretty cool! So you could have any type of hardware (nas, speakers, whatever... and simply upgrade the computer-part (the CM) if you'd need more power, network or whatever.

- dividuum 7y agoThere's also the rather nice CM3-Panel (https://www.acmesystems.it/CM3-PANEL https://www.acmesystems.it/CM3-PANEL) as well as the Artista IoT displays (http://www.apollodisplays.com/iot-compact-panels/ http://www.apollodisplays.com/iot-compact-panels/).
