17. NAND FLASH Interface: easily connects to the NAND FLASH peripherals;
18. LCD Interface: easily connects to the touch screen LCD;
19. ONE-WIRE Interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
20. PS/2 Interface: easily connects to PS/2 keyboard or mouse;
21. USART1 Interface: easily connects to RS232, RS485, USB TO 232;
22. USART2 Interface: easily connects to RS232, RS485, USB TO 232;
23. USB Port: USB communication between board and PC;
24. 5V DC jack;
25. 5V/3.3 V power input/output;
26. MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
27. JTAG/SWD interface: for debugging/programming
28. Boot Mode Selection: for configuring the BOOT0 and BOOT1 pins
29. USB OTG Selection Jumper

• Short the jumper to enable USB OTG, connects to MCU I/O
• Open the jumper to disable USB OTG, disconnects from MCU I/O

30. PS/2 Interface Jumper

• Short the jumper to connect the PS/2 device to default I/Os
• Open the jumper to connect the PS/2 device to custom I/Os via jumper wires

31. LEDs Jumper

• Short the jumper to connect the LEDs to default I/Os
• Open the jumper to connect the LEDs to custom I/Os via jumper wires

32. VBAT Selection Jumper

• Short the jumper to use system power supply
• Open the jumper to make it possible to connect the VBAT to external power, such as battery
