Overview

Open1343 is an ARM Cortex-M3 development board that features an LPC1343 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-M3 microcontroller.

What's On Board

1. LPC1343FBD48/302:the high performance ARM Cortex-M3 LPC MCU which features:
   • Core: Cortex-M3 32-bit RISC
   • Operating Frequency: 72MHz Max
   • Operating Voltage: 2-3.6V (3.3V typical)
   • Package: LQFP48
   • I/Os: 42
   • Memories: 32kB Flash, 8kB RAM
   • Communication Interfaces: 1 x SPI, 1 x SSP, 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 | 6-ch AD interface
    • for connecting accessory boards which using I/O control, such as 8 Push Buttons, Motor, etc.
    • can be used as AD interface for AD testing
11. SPI interface: for connecting SPI peripherals, such as DataFlash (AT45DBxx), SD card, MP3, etc.
12. I2C interface: easily connects to I2C peripherals such as I/O expander (PCF8574), EEPROM (AT24Cxx), etc.
13. ONE-WIRE interface: easily connects to ONE-WIRE devices (TO-92 package), such as temperature sensor (DS18B20), electronic registration number (DS2401), etc.
14. ISP interface (including UART interface): for connecting ISP modules and/or UART peripherals, such as RS232, RS485, USB TO UART, etc.
15. LCD interface: supports connecting the 2.2 inch multi-color touch screen LCD (included in Package A), controlled through SPI, extremely saves more I/O resource
16. USB port: communicating with PC
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 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. ISP jumper: short the jumper while connecting the LPC ISP (mini) accessory board
27. ISP jumper: short the jumper for USB function

Note:
The Open1343 supports programming via UART BOOT LOAD, a USB TO UART accessory board is also provided in the package.
The Open1343 does NOT integrate any debugging function, a debugger is required.
The Open1343 Standard includes only ONE accessory board -- LPC ISP (mini).

JTAG/SWD Interface
