Overview
Compatible with Arduino UNO R3, OPEN-SMART Rich UNO R3 is an ATMEGA328P
development board with rich peripherals. Peripherals include 4 digit display, DS1307 clock, LM75
temperature sensor, infrared receiver, serial MP3 player, rotation angle sensor, 4-channel touch
sensor. Hardware resources are very rich, do not need any DuPont wires, and the usage is very
simple. It is very suitable for Arduino learners.
4 digit display:
4 digit tube (0.36 inches) which can display the clock point, it needs D10/D11
pins to control and display the integer, clock, stopwatch, score and so on.
DS1307 clock:
based on DS1307 high-precision real-time clock module, I2C interface, the
address is 0x68.
LM75 temperature sensor:
I2C interface temperature sensor, not only can measure the
temperature, it can also set the temperature protection temperature, the address is 0x48.
Infrared receiver:
use D2 pin,It can receive the modulated infrared signal of 38KHz that is sent
by the IR transmitter module and demodulate it into logic level, and it can complete the infrared
remote control with the codec program.
Serial MP3:
MP3 music player module is based on high-quality MP3 music chip, use D7 / D8
pins to be software serial port, you can send commands to switch songs, change the volume and
play mode and other operations.
Rotation angle sensor:
10K ohm adjustable potentiometer knob angle sensor, use A0 pin, can be
used for MP3 volume adjustment, 4-digit display brightness adjustment.
4-CH touch sensor: capacitive touch switch, only when you touch the corresponding position with
your fingers, the module corresponding pin (D3 / D4 / D5 / D6) will output high level, otherwise it
outputs low.
Features:
- Use Arduino UNO bootloader
- It is 100% compatible with Arduino UNO R3 program, expansion shields, IDE.
- Use Through Hole Mount type B USB connector, consistent with Arduino UNO R3, ruggedness
and long service life.
- You can burn the program with the type A male to type B male cable.
- Onboard 500mA resettable fuse to protect power supply from the USB port and the DC jack at
the same time.
- USB interface driver chip: CH340G, compatible with win7, win8, linux, MAC OS.
- Microcontroller: Atmel ATmega328P
- Working voltage: 5V
- IO logic voltage: 5V
- Working current: 500mA (Max)
- Digital I/O Pins: 14 (of which 6 provide PWM output)
- Flash Memory: 32 KB of which 2 KB used by bootloader
- SRAM: 2KB
- EEPROM: 1KB
- Clock Speed: 16 MHz
- Onboard DIP switch, you can disconnect the connection between the peripheral module on the
board and the Atmega328P.
- Onboard Arduino Shield interface, can plug the compatible expansion shield.
