Dual USB Type A Connector (USB1/USB3):

USB 2.0 Pin Header (USB2):

MCU Communication Setting (SC3T1): MCU

communication setting jumper

MCU Debug Port (JTAG1): The MCU is provided by NXP’s

LPC1110 which is a ARM-Cortex-M0 based, low-cost 32-bit

microcontroller for 8/16-bit applications. It has a 4 KB on-

chip flash programming memory. The MCU and its flash

will help to retain the DIO last state even when the system

reboots or shuts down.

Clear CMOS jumper (JCCMOS1): It is for clearing the

CMOS memory.

Digital I/O (DI1)

Digital IN/OUT(DIO1) Connector: The 8 pins of digital

Input/Output (GPIO) support input and output operations

through the 2x5-pin terminal block.

TTL Level is +5V; Maximum input/output current for

each port is 100mA
