Interface and Connector description for the JN30D
Please note that the software GPIO number differs from the socket pin. This software GPIO number must be calculated with a special formula and differs between the various compute modules.
Please see our additional information about GPIO´s:
Standard RJ45 pinout with POE capable magnetics class 3 and 4 (PD or PSE). Connected to the Ethernet controller on the compute module.
The J4 uses PCIEx4, we recommend the 128 GB Transcend SSDs (TS128GMTE110S). This SSD is standard in some Auvidea development system offerings.
Please note that only NVME SSDs are supported. SATA SSDs are not supported
22 pin 0.5 mm pitch FPC connector
| Pin | Description | Socket pin | Note |
|---|---|---|---|
This CSI-2 connector has the same 22 pin pinout as the 22-pin connector on the Raspberry Pi Zero and Raspberry Pi compute module dev kit board. With adapter cable, it may connect to Raspberry Pi camera 2.1 and Vision Component camera modules. Alvium cameras require the Alivium adapter.
Pin 6: by default, the device tree puts a PWM signal on pin 206 (LCD_BL_PWM - GPIO_07). For most cameras (like Raspberry Pi camera with iMX219 sensor) this needs to be changed to a constant low output to send a high to the camera for power enable. This is part of the device tree changes.
Some Vision Component camera modules use this pin to synchronize multiple cameras. The pin 5s of all CSI-2 connectors are OR ‘red together and drive the CAM LED output.
Please also see our CSI-Camera guide, for examples and additional information
Please note that on the JN30D each camera connector uses its own I2C bus. This setup is different from the NVIDIA dev kit. If you like to use CSI-2 cameras, please install the Auvidea BSP (firmware).
JST-GH 1.25 mm
Internal USB 2.0 JST-GH connector to connect to internal USB 2.0 add-on modules (like U100, U110, U120, etc.).
Standard pinout
CEC is not supported (pin 13 of HDMI connector)
Power pin 18 is current limited by PTC fuse (5V 50mA)
22 pin 0.5 mm pitch FPC connector
See further details in the J5 description.
USB 3.0 Type A standard pinout
In Rev 1: power control is always on (5V 1A)
In Rev 2 and up: Controllable with GPIO pin 126 power on[0]/off[1] (default on[0]) (5V 1A)
Main power input to the carrier board is the 5V 3A USB-C power connector.
No overcurrent and no reverse voltage protection implemented.
Power is limited by the USB power supply. Alternative 5V powering via the two 5V pins of the GPIO header.
Supports device mode and can be used to flash the compute module.
JST-GH 1.25 mm
Unidirectional directional 1.8V to 3.3V level shifters and 10 Ohm series resistance (plus ESD protection).
CAM_LED flash signal can be used to control external camera LED. When using an external LED, please limit current with an external resistor. Connect cathode to this pin and anode to 3.3V to 12V power. Maximum current 2A.
CAM_LED: open drain output to drive cathode of camera LED.
Controlled by 3 signals which are OR red together:
J5 pin 5 (CSI CD camera)
J10 pin 5 (CSI AB camera)
Compute module Socket pin 218 (0: LED off, 1: LED on, float: LED on)
Pico blade 1.5 mm
This connects to the 4 center pins of the Ethernet magnetics on the cable side to extract or inject POE power. This connector may be used for POE add-on solutions.
Please use any Raspberry Pi hats with care and carefully check compatibility as compatibility was in mind but cannot be guaranteed for all modules.
All GPIO signals are unidirectional (input or output).
Integrated for software protection and licensing.
Model: ATSHA204A
Shows M.2 activity.
Shows Ethernet activity on Socket pin 194 – on[0]/off[1], default: off
At own risk resistor can be moved to control Eth-LED via socket pin 188 (link LED)
Connected to 3.3V power rail. This LED is always on when 3.3V is present on the power rail.
