1. X873 is a perfect storage solution only for Raspberry Pi 4-M.2 NVMe SSD Shield. Supports up to 2TB M.2 NVMe SSD solid state drive. Allows booting the operating system from HDD/SSD for faster opening of applications, network services and file copy. USB3.1 Gen1 5Gb/s connection can provide plug and play function for Raspberry Pi 4.    

2. Super fast data transfer from PC or Mac (USB3.1 Gen2 10Gb/s, Gen1 5Gb/s, USB2.0480Mb/s). Integrated USB 3.1 Gen2 to PCIe Gen3x2 10Gb/s bridge controller. Integrated high-efficiency step-down converter, maximum 3.3V, maximum 3.5A, can power SSD. External self-powered or USB bus powered    

3. X873 Compatible with X735 to provide intelligent power management and cooling function. Compatible with X710, providing wide input voltage (6-36V) and intelligent power management functions. Compatible with X765, provide POE and wide voltage power supply function (POE, 5V 5A). Compatible with X725, provide intelligent power management, remote power on/wake up, and safe shutdown function (18650 UPS, 5.1V8A, wOL)    

4. X735 has been upgraded to the final version X735 V2.5. To use the silent PWM fan, you must install a shell script to make the PWM fan work properly. It is a true multi-function expansion board, suitable for all current Raspberry Pi motherboards with 40pin GPIO pins. (Including pi 4 / 3B + / 3B / 2B / B +). X735 has an onboard switch and reserves two 4PIN power switch ports (reset switch and self-locking switch). You can connect an external power switch to safely control the power on/off.    

5. X735 provides intelligent and safe power management through software, safe shutdown and complete power failure, automatic temperature control fan, and can use the Raspberry Pi under extreme conditions, including extremely high temperature environments. X735 also retains 40pin GPIO pins, which can be stacked with other Raspberry Pi accessory boards to enhance applications.    

[X873 Product Description]    

The new version is named X873 V1.2.    

Update purpose: This upgrade solves the EMC interference problem between Raspberry Pi 4 and USB3.0 devices.Update changes: The x873 removes the DC JACK power interface of the X872, and the X873 is powered by the USB 3.0 connector, which reduces the height of the entire product.    

Note: Like all SSDs, new media must be formatted before use. SSD uses ultra-high-performance storage media, which will run hot under load. Old SSD drives with lower efficiency flash media may not perform as well as new drives    

[X735 Product Description]    

[Power supply mode (requires 5.1Vdc +/-5%, 2.5-4A)]
