CM0IQ outline dimentions are 42x36mm. Four mounting points are M2x0.4 threaded standoffs with 2mm max depth. Standoff height is 1mm
IMPORTANT: screwing deeply than 2mm can permanently damage the board
CM0IQ board has 40-pin 1.27mm pitch GPIO connector, using standard Raspberry Pi GPIO pinout
Pin 1 location:
Connector has standard Raspberry Pi 22-pin DSI connector pinout
DSI displays are not automatically detected and configuration to config.txt shall be added.
Example for 5" Raspberry Pi Touch Display 2:
dtoverlay=vc4-kms-dsi-ili9881-5inch
Note: Raspberry Pi Touch Display 2 5V power has to be provided separately. 5V is available on GPIO connector, as well as on solder pads at the corner of the board
Connector has standard Raspberry Pi 22-pin CSI connector pinout. Camera modules are not automatically detected and configuration shall be added, for example (Raspberry Pi Camera Module 3):
dtoverlay=imx708
| Switch | Off | On |
|---|---|---|
| 1 | Normal operation | nRPI_BOOT low |
| 2 | USB data switched to USB-C connector | USB data switched to USB-A connector |
