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.

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.

Partial Features and Interfaces
Power interface (1)
电源接口使用 XT30PW-M36 接口,与其配对的连接器型号是 XT30U-F,具体定义如下。
- 推荐输入电压为 12V,可支持的电压范围是 10V-30V。欠压保护电压为 9.5V,过压保护 31V。
- 该接口具有反接保护,但原则上任何时候都需检查好极性,确认正确再接入电源。
- 当使用 ORIN NANO 系列时,请保证输入电源拥有最少 45W 的输出能力,使用 ORIN NX 系列时,请保证输入电源拥有最少 60W 的输出能力。
| 核心卡 | 推荐的电源输出能力 | 使用 USBC-PD 供电需要支持 |
|---|---|---|
| ORIN NANO 4G/8G | 45W | 最少 20V 2.25A 协议 |
| ORIN NX 8G/16G | 60W | 最少 20V 3A 协议 |
REC 按钮 (4)
C2401 载板有两种方式进入恢复模式:
- 方式一(按键法): 在断电的情况下,按下 REC 按钮不放,再接通电源,即可进入恢复模式,进行刷机等操作(请注意,恢复模式仅持续 60 秒,系统检测到无刷机操作后,会自动进入正常开机时序。)
- 方式二(拨码法): 将载板背面的拨码开关 3 拨动至 ON,这样在每次上电时,系统都将会进入恢复模式。
启动按钮 (5)
C2401 设置了一个启动按钮,该按钮具有以下功能:
- 系统启动时:按动一次进入关机界面,长按 10 秒强制关机。
- 系统关闭时:按动一次进行开机。
- 禁用自动开机: 将载板背面的拨码开关 2 拨动至 ON,将禁用上电自动开机,需手动按动启动按钮进行开机。
拓展排母 (18)
该排母规格为 2x15P 1.27mm,第一脚及定义如下:
- VCC IN 的电压大小取决于输入电压,最大不能超过 3A,VDD_5V 和 VDD_3V3 最大能提供 1A 电流。
- I2C、GPIO、SPI、UART 电平均为 3.3V。
- PG 信号:当上层板正常工作时,输出高电平。
- 13、15、19、21 这组 USB3.0 接口,在使用官方固件的情况下默认是关闭的,开启教程请参考设备树替换说明。
