# Mechanical
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

# GPIO Connector
CM0IQ board has 40-pin 1.27mm pitch GPIO connector, using standard Raspberry Pi GPIO pinout

Pin 1 location:

# DSI Connector
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

# CSI Connector
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
```

# DIP-switch

| Switch         | Off                                  | On                                    |
| -------------- | ------------------------------------ | ------------------------------------- |
| 1              | Normal operation                     | nRPI_BOOT low                         |
| 2              | USB data switched to USB-C connector | USB data switched to USB-A connector  |
