Product Description

Arduino UNO R3 development sensor expansion board

The role of UNO expansion board:

The UNO expansion board adopts a laminated design, which not only expands all the digital and analog interfaces of the Arduino controller in the form of servo line sequence, but also specially designed: IIC interface, servo interface, serial Bluetooth module interface, TTL communication interface, SD Card module communication interface, ultrasonic sensor interface, SPI communication interface, 12864 LCD serial and parallel interface, independent lead to make it easier to use. For novices, no more headaches for cumbersome and complicated circuit wiring. This sensor expansion board really simplifies the circuit and can easily connect common sensors. A sensor only needs a general 3P sensor. Connection line (regardless of digital connection line and analog connection line). After completing the circuit connection, write the corresponding program and download it to the controller to read the sensor data, and easily complete your own interactive works.


Product parameters:

Support motherboard model: Arudino UNO R3 development board, directly plug-in use.

I/O lead quantity: 13 digital I/O ports and 6 analog I/O ports are all lead out.

Interface form: 2.54 pitch 3P pin header standardized design and color distinction.

Pin header interface function: independent I2C, ultrasonic, SD card reader module, TTL communication and other interfaces.

Row socket interface function: independent SPI and Bluetooth module socket design.

Reset function: integrated motherboard reset button, support direct button reset on the expansion board.

Status indication: integrated LED power signal indicator and demonstration of the function of one IO port.

Power supply options: It can be directly powered by the Arduino motherboard, or independently powered by a 5V power supply terminal block.
