Bảng Mạch Mở Rộng X735 V2.5 Pwm Cho Raspberry Pi 4b / 3b + / 3b

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 +).
It 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.
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.

Update changes: Use silent PWM cooling fan, support fan speed controlled by script, support reading fan speed.
Support TRUE AUTO ON function (in the old version, if AUTO ON is enabled, the power management function will be disabled)
Considering that some customers use X735 with other DAC shields, we adjusted the GPIO pins used.
Please install the Shell script to obtain a safe shutdown function. Please refer to raspberrypiwiki.com/X735
