Overview

Open11C14 is an ARM Cortex-M0 development board that features an LPC11C14 device as the microcontroller. It supports further expansion with various optional accessory boards for specific application. The modular and open design makes it the ideal for starting application development with ARM Cortex-M0 microcontroller.

What's On Board

   • Package: LQFP48
   • I/Os: 42
   • Memories: 32kB Flash, 8kB RAM
   • Communication Interfaces: 1 x CAN, 2 x SPI, 1 x UART, 1 x I2C, 11 x PWM, 8 x ADC
   • Debugging/Programming: supports SWD interfaces, supports ISP through UART
2. AMS1117-3.3: 3.3V voltage regulator
3. Power switch
4. Power indicator
5. LEDs: convenient for indicating I/O status and/or program running state
6. Reset button
7. User keys: for I/O input test and/or program control
8. Joystick: five positions
9. 12M crystal oscillator: enables the MCU run at 48M frequency by frequency multiplication
10. 8 I/Os interface | 8-channel AD interface
• for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc.
• there's also 8-channel AD interface can be used for AD testing
11. SPI0 / SPI1 interface: for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc.
12. I2C interface: for connecting I2C peripherals, such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc.
13. 1-WIRE interface: for connecting 1-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
14. UART interface: for connecting UART peripherals, such as RS232, RS485, USB TO UART, etc.
15. LCD interface: for connecting 2.2 inch multi-color touch screen LCD which using SPI control
16. CAN interface: communicates with accessory boards which feature the CAN device conveniently
17. PS/2 interface: easily connects to PS/2 keyboard and/or mouse
18. 5V DC jack
19. 5V/3.3V power input/output: usually used for power supply output, and/or common ground with other application board
20. MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
21. SWD interface: for debugging/programming
22. LEDs jumper
23. User keys jumper
24. Joystick jumper
25. PS/2 jumper
26. UART ISP jumper: short the jumper while In-System-Programming through UART
27. CAN ISP jumper: short the jumper while In-System-Programming through CAN
