It boasts comprehensive connectivity options, including dual Ethernet ports, dual USB ports, and expansion support for 4G/5G modules. Its space-saving stacked design ensures excellent ease of integration. 正面 背面 Features   Equipped with an advanced automotive-grade E-fuse chip, providing comprehensive protection against over-voltage, under-voltage, short-circuit, over-current, and reverse polarity. Utilizes an ultra-low-resistance Buck chip, matched with an advanced alloy flat-wire inductor, featuring low heat generation and high saturation current characteristics to ensure stable power supply to the module. Features an 8-layer, 2u gold-plated, via-in-pad (VIP) process PCB, combined with a compact, high-density design, resulting in an external dimension of only 55x92mm. Rich peripheral interfaces, including dual USB 3.0 ports and dual network ports (Ethernet). One of the 2.5G ports supports the PTP (Precision Time Protocol) and high-density jumbo frames up to 16K bytes. The M.2 interface is designed on the same side for excellent accessibility and practicality. This allows for the replacement of the Wi-Fi card or solid-state drive (SSD) without needing to dismantle the module. It also includes a secondary development interface for expansion, such as 4G/5G network adapter. 产品规格 Supply Voltage 12V (compatible with 9.5V-30V) Power Connector XT30 interface Supported Module Orin Nano 4G/8G Orin NX 8G/16G Ethernet 1x Gigabit Ethernet Socket (RJ45) , supports 9KB   jumbo frames 1x 2.5G Ethernet Socket (RJ45) , supports 16KB jumbo frames and PTP protocol Wireless Network 1x M.2 Key E ( 2230 )   External Storage 1x M.2 Key M (2230 NVME SSD) DisplayPort 1x Mini HDMI V2.1 USB 2x USB3.2 (10Gbps) 1xUSB2.0(GH1.25-4p) USB-C 1x Type C (USB 2.0) for firmware flashing Camera 1x CSI-22P Other UART, CAN, I2C RTC 1x RTC backup clock battery interface Operating Temperature 0℃~45℃ l The carrier board requires a 12V(compatible with 9.5-30V) DC power supply. To ensure normal system operation, a power adapter with sufficient current output must be used. Additionally, under high load conditions with an input voltage exceeding 15V, adequate heat dissipation must be provided to prevent overheating. l This product includes reverse-polarity protection. Nevertheless, do not connect the power supply in reverse. l The overcurrent protection (OCP) threshold for all USB ports is 2.5A. Exceeding this limit will trigger an automatic power-off. l In contrast to the original M.2 2230 interface, the backplane's network interface now features a symmetrical layout. Do not hot-swap the module. Always power off the board before inserting or removing the module. Failure to do so may damage the module and the carrier board. Damage caused by improper operation is not covered under warranty.

(Note: Recovery mode lasts only 60 seconds. The system will automatically resume normal startup after detecting no connection.) Set the DIP switch 3 on the back of the carrier board to ON, enabling the system to automatically enter recovery mode upon each power-on. Power Button (5) l The C2401 unit is equipped with a power button (5) that performs the following functions:   When the system starts: Press once to enter the shutdown interface, and hold for   10 seconds to force shutdown.   When the system is shutting down: press once to start up. Disable automatic startup: Set the DIP switch 2 on the back of the board to ON to disable automatic power-on. Manually press the power button to power on. Expansion Header (18) This is a 2x15-pin, 1.27mm pitch female header . Pin 1 location and pin definitions are as follows: l  The VCC IN voltage matches the input voltage (Pass-through), with a max current of 3A. VDD_5V and VDD_3V3 provide up to 1A each. l The I2C, GPIO, SPI, and UART pins operate at 3.3V .. l PG signal: Outputs a high level (Active High) when the module is operating normally. l USB 3.0 ports 13, 15, 19, and 21 are disabled by default in the official firmware.
