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. The kit contains TF card£¬ speaker£¬ CR1220 battery£¬ infrared remote control£¬ and these are the necessary accessories for MP3£¬DS1307£¬ infrared receiver. 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.
