3.1.8. DIO Interface

There is a four port DIO interface available on the front of the BL Pi-Tron CM3+, see Figure 5 (pos. 8).
The DIO pins consist of a 24 V high side switch, capable of driving 800 mA. The voltage level is according to the
supply voltage. When the output is disabled, the pin can be used as 24 V input.
The DIO interface is not designed for connecting cables longer than 30 m.
For the pin assignment of the DIO connector, refer to Chapter 3.2.7: DIO Connector (X19).

3.1.9. USB OTG Interface

There is a Micro-USB OTG interface for programming the eMMC or microSD card, see Figure 5 (pos. 9).
The USB OTG interface is for service and should only be used by qualified personnel.
For the pin assignment of the USB OTG connector, refer to Chapter 3.2.8: USB OTG Connector (X402).

3.1.10. MicroSD Card Slot

The Pi-Tron can be obtained with two different types of Compute Module. One without
eMMC
version, and the " " version. The notable difference between the
Lite
the " " version can only boot and use the microSD card and the "
memory, but not the microSD card. If there is a MicroSD card slot, see Figure 5 (pos.10).
For the pin assignment of the MicroSD card slot, refer to Chapter 3.2.9: MicroSD Card Slot (X400).
microSD Cards/SSD drives Kontron Electronics recommends checking the condition
regularly.
3.1.11. +5 V Display Connector
There is a +5 V connector intended to supply a display or other devices, see Figure 5 (pos. 11). In the standard
version, the +5 V connector is not fitted.
For the pin assignment of the +5 V Display connector, refer to Chapter 3.2.10 +5 V Display Connector.

3.1.12. CSI (Camera Serial Interface)

There is a CSI interface to connect a Raspberry Pi compatible camera, see Figure 5 (pos. 12). For the pin assignment
of the CSI connector, refer to Chapter 3.2.11 CSI Connector (Camera Serial Interface, X1001).

3.1.13. DSI (Display Serial Interface)

There is a DSI interface to connect a Raspberry Pi compatible display, see Figure 5 (pos. 13). For the pin assignment
of the DSI connector, refer to Chapter 3.2.12 DSI Connector (Display Serial Interface, X1000).
