Re: Seeeduino Arch Pro - can't power it up using VIN pin.

Hello,

Sorry for the inconvenience caused. The Vin input is not connected to anything. The Arch Pro is designed to be powered from 5V pin (use regulated 5V). You can also power the board using micro USB port.

Re: Motor Shield V1 + Potentiometer

Hello,

The Seeed Motor Shield v1 has many Grove connectors (including those connected to analog inputs of Arduino). Use one of them to connect a Grove_-_Rotary_Angle_Sensor (i.e POT) or Grove_-_Rotary_Angle_Sensor or your own potentiometer.
