SECTION 2
OVERVIEW
2.1 Jetson Nano
This new JNX30D carrier board turns the Jetson Nano compute module into a super mini computer.
The Nano offers very high computational (quad core ARM® Cortex®-A57 with up to 1.43 GHz) and
graphical (NVIDIA Maxwell™ with 128 CUDA cores)
processing performance in a tiny form factor.
2.2 JNX30D
§ Easy aluminum case integration
§ Easy flashing: just connect a USB OTG cable
§ High performance storage: M.2 NVME PCIe x4
§ 2 versions support either Nano dev kit module (with SD card - 38346-3) or Nano production
module (with eMMC - 38346-4)
2.3 Applications
§ Industrial AI computers
§ Digital signage systems

4.18 LED - Eth
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)
4.19 LED - Over current
Placed between J1 (Power connector) and J3 (Ethernet).
Shows over current of integrated 5V power supply. If 8A is acceded the power output is disabled, and
the LED is activated to red. To reset this over current condition power input must be cycled.
The 5V power supply mainly powers the 5V compute module, USB ports and the 3.3V power
controller for the M.2 socket.
4.20 LED - PWR
GPIO pin 178 on[1]/off[0], default: off[0]
4.21 Micro SD-card reader
Standard pinout.
Needs device tree changes to be activated which includes enabling Socket pin 211.
