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.
* FOR USE WITH
Raspberry Pi 1 Model B+/ 2 Model B / 3 Model B / 3 Model B+ / 3 Model A+
OPERATING SYSTEM
Raspbian Stretch
Safe shutdown function tested for Raspbian, other operating systems to be tested and advised
Features
Intelligent and safe power management
Equipped with both momentary button and latching switch for easy power control
Press the momentary button to turn on
Press the momentary button and hold for 1~2seconds to reboot
Press the momentary button and hold for 3~7seconds to implement safe shutdown
Press the momentary button and hold for >8seconds 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
Note:
* 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
Reserved 40-pin stackable Header for Add-On Boards
Works with all current models of the Raspberry Pi using a 40 pin header
On-board micro-USB socket for power input - No need to change the power adapter
Fully compatible with X820, X850, X860, X870, X822, X852 to provide intelligent and safe power management
Specifications
Power supply: 5.1Vdc +/-5%，2.5~4A
Board size: 65 x 58mm
Note
Full poweroff through software is not supported when using latching power switch
Do not apply power to your Raspbeery Pi via the Pi's Micro-USB socket
1. X735 powers the Raspberry Pi via the 40-pin header (Pin 2 & 4)
2. Don't power the Raspberry Pi via the Pi's Micro USB socket
3. X735 can be powered via the onboard DC jack or Micro USB power socket or XH2.54 connector.
Select momentary power button or latching power switch
Power adapter must be disconnected when selecting momentary button or latching switch.

Board Assembly
Push a screws (M2.5*6mm) up through the mounting hole on the underside of the Raspberry Pi.
Screw the spacer (M2.5*12mm) down until it is hand tight
Plugs the X735 board straight into your Raspberry Pi B+'s GPIO header and screw down (M2.5*6mm)
Optional -To use with X820/X850/X822/X852/X860/X870
a) Unscrew 4 screws on the topside of Raspberry pi
b) Screw the M/F spacer (M2.5*12 / M2.5*20) down until it is hand tight
Plugs the X735 straight into your Raspberry Pi's GPIO header and screw down (M2.5*6mm)
Connect the 2-pin power connection wire from the 5V connector on X735 to X820/X850/X822/X852/X860/X870
