Raspberry Pi 4 Model B X832 Storage Expansion Board Supports 3.5 inch SATA HDD Compatible with Pi 4B customize

• Not include Raspberry Pi 4 and 3.5'' SATA HDD

• Compatible with Raspberry Pi 4 Model B noly

• A microSD card is required for forcing the Raspbian OS to use the HDD/SSD for its "root" partition

• For use with original power supply unit only

• Don't power your Raspberry Pi via the Pi's 40-pin header and Type-C power socket at the same time.

• Power supply is very important to the hard disk, so please use a high quality power adapter, or you may encounter problems such as not recognizing the hard disk

• When use X735 with X835/X832, please DO NOT power from X735, please power via X835/X832 DC 12V IN PORT.

1. There are 4 version of X735: V1.0, V2.0, V2.1, V2.5 (final version): Version 2.5(Updated on Mar. 15th, 2021):

Some new features of X735 v2.5:

• Use the silent PWM cooling fan, and support fan speed is control by script, support read fan speed, and we provide sample python code.

• You must install shell script to enable the PWM fan work fine since it's a PWM fan, refer to X735 V2.5 Software

• Support TRUE AUTO ON function (in the old version,the power management function is disabled if AUTO ON is enabled)

• Considering that some customers use X735 together with other DAC shield, we adjusted the GPIO pins used.

• Please install shell script to get safe shutdown function. please refer to X735 V2.5 Software

• No any size changes.

Intelligent and safe power management：

• Equipped with both momentary button and latching switch for easy power control

• Press the momentary button or external momentary power switch to turn on

• Press the momentary button or external momentary power switch and hold for 1~2seconds to reboot

• Press the momentary button or external momentary power switch and hold for 3~7seconds to implement safe shutdown

• Press the momentary button or external momentary power switch and hold for more than 8 seconds to force shutdown

• Supports safe shutdown and full poweroff through software

• On-board switch convenient to select latching or momentary power control switches

• Press the latching power switch once to turn on and again to implement safe shutdown

• On-board LED shows the status of power on, reboot and shutdown

• On-board PH2.0 connectors allows to use external latching switch or momentary button

• Powers the Raspberry Pi via the 40-pin header - no additional cabling required

• Allows power input via DC jack or Micro-USB socket or XH2.54 connector

• Allows power output via XH2.54 socket and or the 40-pin header

Auto cooling function

• Dual trip point temperature controlled cooling fan

• Auto-Control the fan for Cooling / quiet Operation

• Board temperature ≤34C - Fan running at low speed

• Board temperature ≥34C - Fan running at medium speed

• Board temperature ≥45C - Fan running at full speed

• On-board LEDs show the status of fan running low and high

• No driver and additional setting required for the cooling fan

Others

• Reserved 40-pin stackable Header for Add-On Boards

• Works with all current models of the Raspberry Pi using a 40 pin header

• Fully compatible with our products X820, X850, X860, X870, X822, X852 to provide intelligent and safe power management

• Four kinds of power source:(DC5525, Micro USB, Type C, XH2.54 2-Pin cable)
