At present, the air plate in the general board on the market can be compatible with very small DC

When the indoor unit and outdoor unit are all DC fans This module can solve the problem

This product is a five lineDC fan drive plate。

1. PCBPlate size：100*58mm，Double sidedFR-4 1.6MMBoard design。

2. The main filter capacitor is special for power supply450V/150uFHigh frequency low resistance capacitor（Temperature resistance105℃）

3. Via on-board potentiometer，Or use MCU outputPWMPort control motor speed（terminal2.54-4P）

be careful：When driven by single chip microcomputer，It needs to be connected with the single chip microcomputer5VCCPower supply is enough。

4. There are two groups on the boardVH3.96-6P（2Empty needle）Interface，Two groups of fans can be controlled separately（Inlet and outlet air）
