      Update notification:The X735 has been update to X735 V3.0 version at

      There are 5 version of X735: V1.0, V2.0, V2.1, V2.5 V3.0:

      Version 3.0(Updated on March, 2022):

      Some new features of X735 V3.0:

      • Support width voltage DC 6V-30V input (only DC port), you still can use 5V PSU via Type-C or Micro USB port. the DC connector is changed from DC5525 to DC5521
      • Remove the latching switch connector(the latching switch is no longer supported and replaced by a XH2.54 5V OUT connector;
      • Replace the L-SW jumper with FAN FS jumper to control the PWM fan;(Because we found that there are some beginner who don't know how to install the script to make the PWM fan run, or the installation script doesn't support 3rd party OS, at this time, you just need to remove the FAN FS jumper, the PWM fan will run at full speed.)

      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. The X735 also reserves the 40-pin header that can be stacked with other Raspberry Pi accessory boards for enhanced applications.

      User Manual:


      1. You must install shell script to enable the PWM fan work since it's a PWM fan, refer to X735 Software on wiki page.
      2. Do not apply power to X735 via Type-C or Micro-USB and via DC 5521 Jack 6-30V at the same time!!!
      3. Do not apply power to your Raspberry Pi via the Pi's Micro-USB or Type C socket; Pls apply power to X735.
      4. When use X735 V2.5/V3.0 with X835/X832, please DO NOT power from X735, please power via X835/X832 DC 12V IN PORT!!!
