Produktinformation

Important Note: This script guide is only for X735 V2.5 shield based on RASPBIAN. (Not tested on Ubuntu, openmediavault or other OS.)

There are 4 version of X735: V1.0, V2.0, V2.1, V2.5 (final version): Version 2.5(Updated at April 2021 on amazon):

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.

Update History:

  1. On March 15th, 2021, we release the final version X735 V2.5 which use the silent PWM cooling fan, and support fan speed is control by script, support read fan speed, and we provide sample python code.
  2. On November 8th, 2019, we release the newest version X735 V2.1, change jumper 'FAN_HS' to 'AUTO ON' function; as we found 'AUTO ON' function is more useful to user.
  3. On August 12th, 2019, it updated to X735 V2.0: add the TYPE C port to POWER the Raspberry Pi 4; (remain the other DC, MICRO USB and XH2.54 power port), and also compatible with Raspberry Pi 3B+ and previous versions.
  4. On April 13th 2019, we firstly release the X735 V1.0 board.

[Overview]

The X735 is a multifunctional expansion board for all current models of the Raspberry Pi using a 40-pin header. It provides intelligent and safe power management, safe shutdown and full poweroff through software, an automatic temperature controlled fan which enables the use of the Raspberry Pi in extreme conditions including very high temperature environments.

X735 PWM Fan Power Management Board

[Features]

Intelligent and safe power management:

  • Press the power button to turn on
  • Press the button and hold for 1~2 seconds to reboot; 3~7 seconds for safe shutdown; gt;8 seconds to force shutdown
  • Supports safe shutdown and full power off through software
  • On-board LED shows the status of power on, reboot and shutdown
  • Powers the Raspberry Pi via the 40-pin header - no additional cabling required

PWM cooling fan(control by script):

  • Dedicated PWM cooling fan for Raspberry Pi
  • Air flow up to 6.01CFM and maximum speed of 5000 RPM
  • Real-Time fan speed reading
  • Programmable temperature and fan speed

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

  • Works with all current models of the Raspberry Pi
  • Reserved 40-pin stackable Header for Add-On Boards

[FAQ]

Q: Why the X735 V2.5 cooling fan not rotate after the installation?

  • Answer:You must install shell script to enable the PWM fan work fine since it's a PWM fan, refer to X735 V2.5 Software: wiki.geekworm.com/X735_V2.5_Software

"u"2.What if I connect the x820 XH2.54 5v to the IN of the X735, and then connect the power supply to the x820. Will the safe shutdown work?

  • Answer: This is no suggested, because power supply for X820 cannot be controlled by X735 and safe shutdown won't be implemented as well. You need to power from the X735 5V IN DC port.

3.Does the X735 power board work with the rock64 board? is the 40 pin connector compatible with the rock64 40 pin connector?

  • Answer: In fact, we didn't test X735 based with ROCK64, and we didn't consider ROCK64 board when we wrote a safe shutdown shell script, so we think X735 is not compatible with ROCK64. Also the PIN definiton of ROCK64 is different with Raspberry Pi. So it is not suggest to use X735 board with ROCK64.
