IOREF pin

for Version 1.2:

The board's IOREF pin is connected with pin 5V! So when adding the DRI0009 to the

stack of board (controller), the controller's supply voltage would changed to 5V! So it

only can be compatible with the controller working at 5V. If you need to use controller

working at other voltage, e.g. 3.3V, you need CUT OFF the IOREF pin of DRI0009.

We are deeply sorry about the mistake! We will revise the design in the next version.

PinOut

Control Mode Selection Jumpers:

The shield supports PWM and PLL(Phased Locked Loop) control Modes. The PWM mode uses

E1 and E2 to generate PWM signal. The PLL mode uses M1 and M2 to generate phase control

signal.
