3.1. Functional Description
The board layout with the main functional features is shown in Figure 2. Several connectors are provided for the
power supply, motor, sensors, external power module, debugging tools, personal computer GUI and user SPI
port. Push buttons and potentiometer are provided for standalone operation control. A 96x64 dot graphic LCD is
used to display motor parameter data such as RPM, Current, Voltage, etc.

Figure 2 Board functional layout
The kit uses the Renesas Rx62T as the main microcontroller to control up to two 3-phase motors. A second
Renesas H8S microcontroller is used to provide UART to USB translation for the GUI as well as galvanic
isolation from the high-voltage motor drives. The isolated power supply for the H8S is derived from the USB
bus voltage.
