Overview

Open1114 is an ARM Cortex-M0 development board that features an LPC1114 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

1. LPC1114FBD48/302:the high performance ARM Cortex-M0 LPC MCU which features:
   • Core: Cortex-M0 32-bit RISC
   • Operating Frequency: 50MHz Max
   • Operating Voltage: 1.8-3.6V
   • Package: LQFP48
   • I/Os: 42
   • Memories: 32kB Flash, 8kB RAM
   • Communication Interfaces: 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. ISP | UART interface: for connecting ISP modules and/or UART peripherals, such as RS232, USB TO UART, etc.
15. LCD interface: for connecting 2.2 inch multi-color touch screen LCD which using SPI control
16. 5V DC jack
17. 5V/3.3V power input/output: usually used for power supply output, and/or common ground with other application board
18. MCU pins connector: all the MCU pins are accessible on expansion connectors for further expansion
19. SWD interface: for debugging/programming
20. LEDs jumper
21. User keys jumper
22. Joystick jumper

For jumper 20-22:

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