  12. 16 I/Os interface | 8-bit AD interface
  • for connecting accessory boards which using I/O control, such as FT245 USB FIFO, 8 SEG LED, etc.
  • there's also 8-bit AD interface can be used for AD testing
8 I/Os interface: for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc. SPI interface: for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc. I2C interface: for connecting I2C peripherals, such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc. 1-WIRE interface: for connecting 1-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc. UART interface: for connecting UART peripherals, such as RS232, RS485, USB TO UART, etc. PS/2 interface: for connecting PS/2 keyboard and/or mouse Graphic multi-color LCD interface: for connecting 2.2 inch multi-color touch screen LCD which using SPI control Character LCD interface: for connecting character LCD, such as LCD1602 (3.3V blue backlight) 5V DC jack Custom crystal socket VCC power input/output: usually used for power supply output, and/or common ground with other application board MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion ICSP interface: for debugging/programming LEDs jumper User keys jumper Joystick jumper PS/2 jumper 1-WIRE jumper Buzzer jumper IR jumper VCC selection jumper Crystal selection jumper RA4 pull-up jumper

For jumper 26-32:

  • short the jumper to connect to I/Os used in example code;
  • open the jumper to connect to other custom pins via jumper wires.
