core resources, the following parameters for the LPC1114FBD48/302: 
kernel: Cortex-M0 32-bit RISC; 
operating frequency: 50MHz Max; voltage :1.8-3 .6 V; 
package: LQFP48; I / O ports: 42; 
storage resources: 32kB Flash, 8kB RAM; 
interface resources: 2 x SPI, 1 x UART, 1 x I2C, 11 x PWM, 8 x ADC; 
debug Download: debugging can be downloaded through the SWD interface, via UART interface ISP.

• AMS1117-3.3

3.3V regulator device.

[Other Devices Profile]

• Power Switch

• Power LED

• User LED

to facilitate I / O output test or show the program running.

• Reset button

• ISP button

with the reset button can be achieved through the serial port ISP

• User presses a key

to facilitate I / O in the test or control program running;

• Joystick

up, down, left, right, down, a total of five states.

• 12M crystal oscillator

frequency can be set, so that frequency is 48M.

[Introduction to module interface]

• 8I/Os | 8-bit AD interface,

easy access to all kinds of uses I / O control module. 
Such as 8-bit key modules, motor control module. At the same time, the interface for AD interface, you can easily AD tests.

• SPI0 / SPI1 interface to

facilitate access to the SPI module. 
If Dataflash AT45DBXX, SD card, MP3 and other modules.

• I2C interface

for easy access to the I2C module. 
Such as I / O expansion chip PCF8574, EEPROM AT24CXX modules.

• ONE-WIRE interface to

facilitate access to ONE-WIRE devices (TO-92 package). 
Such as temperature sensor DS18B20, DS2401 and other electronic registration module.

• UART interface

UART interface with easy access to the device. 
Such as RS232, RS485, USB TO UART modules.

• LCD interface

for easy access to LCD + touch screen module. 
Package distribution of the LCD touch screen 2.2-inch LCD, using the SPI interface, greatly reduce the I / O resource consumption.

[Other Interface Overview]

• 5V DC Interface

• 5V and 3.3V power supply input and output interfaces

commonly used in the external power supply, or the board of the user to handle.

• MCU pin interface

leads to all the pins, convenient and peripherals I / O connections.

• SWD interface,

download and debug support.

[Jumper]

• Users LED jumper

short jumper: access to the sample program specified I / O; 
disconnect jumper: can be changed using the cable access custom I / O.

• User key jumper

short jumper: access to the sample program specified I / O; 
disconnect jumpers: cable access can be changed using custom I / O.

• Five-way joystick jumper

short jumper: access to the sample application specific I / O; 
disconnect jumpers: cable access can be changed using custom I / O.
