SECTION 3 Overview
3.1 Jetson compute module
This new JNX30D carrier board has been designed for the Jetson Xavier NX primarily, but it also
supports the TX2 NX and Nano compute modules. A 5V 8A on-board power converter supports the
high power modes of the Xavier NX.
3.2 JNX30D
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.
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 JNX30D.

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.

reverse voltage protection
over voltage protection (SMA6J18A/CA) with max 20V peak
2
GND
Reverse voltage protection also functions as back power protection if PoE injection is used with J32
pin 2. If a voltage higher than 19V is applied, the TRS diode will heat up and possibly get damaged.
5.2 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.
5.3 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.
