4.15 RGB LED U10 (JP24, JP26, JP27)
The RGB LED is connected to the pins of MCU's Stepping Motor Controller module. They
can be controlled using PWM signals generated by this module.
JP24
This jumper connects the RGB LED (red) to the PWM2P2 of the MCU.
JP26
This jumper connects the RGB LED (green) to the PWM2M2 of the MCU.
JP27
This jumper connects the RGB LED (blue) to the PWM1P3 of the MCU.

4.16 QVGA Display Connector X3 (JP30, JP31)
The display requires initialization before it can be used. This initialization is performed using
the SPI interface of the display which is connected to the MCU through the jumpers, JP30
and JP31.
JP30 Connects MCU's SPI Clock (SCK1) to display SPCLK
JP31 Connects MCU's SPI Data (SOT1) to display SPDAT
