SECTION 3 Overiew
3.1 Jetson compute module
This new JN30D carrier board has been designed primarily for the Jetson Nano compute modules.
When using other modules like the Jetson NX power limits may be exceeded as the USB C power
supply only supplies up to 3A. More power may be supplied to the board via the two 5V pins on the
GPIO header. In this case the USB supply should not be connected.
3.2 JN30D
Easy integration into passively cooled systems
Optionally available as complete system in passively cooled enclosure
Easy flashing: just connect a USB OTG cable (Auto Flash)
High performance storage: M.2 NVME PCIe x4

SECTION 4 Features
4.1 GPIO-Header
A 40 pin 2.54mm header for GPIO, I2C, I2S and UART. Die pinout is similar to the GPIO header on the
NVIDIA dev kits and on the Raspberry Pi. Please note that all signals (except I2C) have uni-directional
level shifters. In other boards some of these signals may be bi-directional which may cause
compatibility issues. Auvidea does not guarantee the compatibility to any specific add-on boards.
Please check the compatibility yourself. Some signals are 5V tolerant inputs and therefore may be
driven from 5V logic outputs.
The 40 pin GPIO header is included (but not soldered in).
4.2 Crypto chip
The crypto chip has been added to support software licensing and copy protection. Please check the
data sheet of the manufacturer for details.
Model: ATSHA204A-MAHCZ-T
https://ww1.microchip.com/downloads/en/DeviceDoc/ATSHA204A-Data-Sheet-40002025A.pdf
4.3 MCU
A MCU for additional power management and watchdog functions is optional. It is standard on some of the
extended versions of the JN30D.

SECTION 5 Pinout description
Please note that the software GPIO number differs from the socket pin number. This software GPIO
number must be computed with a special formula and differs between the various compute
modules. Please see appendix B for details.
5.1 J3 - Ethernet (GbE)
Standard RJ45 pinout with PoE capable magnetics class 3 and 4 (PD or PSE). Connected to the
Ethernet controller on the compute module.
5.2 J4 - M.2 PCIEx4 NVME SSDs
Please note that only NVME SSDs are supported. SATA SSDs are not supported. We recommend the
128GB Transcend SSDs (TS128GMTE110S). This SSD is standard in some of the Auvidea development
system offerings.

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).
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 synchronise multiple cameras. The pin 5s of
all CSI-2 connectors are OR ‘red together and drive the CAM LED output.
