    • Debugging/Programming: supports SWD interfaces, supports ISP through UART
  2. AMS1117-3.3: 3.3V voltage regulator
  3. LM3526-L: USB power switch and over-current protection
  4. Power switch
  5. Power indicator
  6. LEDs: convenient for indicating I/O status and/or program running state
  7. USB communication indicator
  8. Reset button
  9. User keys: for I/O input test and/or program control
  10. Joystick: five positions
  11. 12M crystal oscillator: enables the MCU run at 48M frequency by frequency multiplication
  12. 32.768K crystal oscillator: for internal RTC, also supports clock calibration
  13. USB HOST port: for connecting USB flash drive, etc.
  14. CAN2 interface: communicates with accessory boards which feature the CAN device conveniently
  15. CAN1 interface: communicates with accessory boards which feature the CAN device conveniently
  16. I2C0 interface: easily connects to I2C peripherals such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc.
  17. SPI0 | SPI1 interface: for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc.
  18. Ethernet interface: easily connects the MCU to ethernet network by using an additional ethernet module, such as DP83848 Ethernet Board, etc.
  19. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
  20. I2S interface (including I2C1, I2C2 interfaces): easily connects to I2S and/or I2C peripherals such as Stereo Audio Device (UDA1380), FRAM (FM24CLxx), etc.
  21. LCD interface: combined with an 8-bit to 16-bit adapter, supports connecting the 3.2 inch multi-color touch screen LCD (the adapter and LCD are included in Package A/B)
  22. UART2 | UART3 interface: for connecting UART peripherals, such as RS232, RS485, USB TO UART, etc.
  23. PS/2 interface: easily connects to PS/2 keyboard and/or mouse
  24. Modem interface (including UART1 interface): for connecting Modem and/or UART peripherals, such as RS232, RS485, USB TO UART, etc.
  25. 8 I/Os interface (including 3-ch AD, 1-ch DA)
    • for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc.
    • also integrates AD/DA function for AD/DA testing
  26. ISP interface (including UART0 interface): for connecting ISP modules and/or UART peripherals, such as RS232, RS485, USB TO UART, etc.
  27. USB port: communicating with PC
  28. 5V DC jack
  29. 5V/3.3V power input/output: usually used for power output, and/or common ground with other application board
  30. MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
  31. JTAG/SWD interface: for debugging/programming
  32. LEDs jumper
  33. User keys jumper
  34. Joystick jumper
  35. PS/2 jumper

For jumper 32-35:

  • short the jumper to connect to I/Os used in example code
  • open the jumper to connect to other custom pins via jumper wires
  1. ISP jumper: short the jumper while connecting the LPC ISP (mini) accessory board
  2. 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

The Open1768 supports programming via UART BOOT LOAD, a USB TO UART accessory board is also provided in the package.
The Open1768 does NOT integrate any debugging function, a debugger is required.
The Open1768 Standard includes only ONE accessory board -- LPC ISP (mini).
