Keyestudio Proto Shield is particularly designed for the Arduino UNO R3. It makes it easy for you to design custom circuits and solder electronics directly on it.For convenient use, there is a large prototyping space of both connected and unconnected spaced through-holes on the shield.There is also a soldering position reserved for SMD chip on the protoshield. You can easily solder SMD ICs on the prototyping area to test them with your Arduino board.

lCan be plugged into the Arduino controller.

lExtend 5V, 3V and Arduino Vin voltage.

lComes with a Reset button.

lExtend out all control pins and power pins of the Arduino.

lAble to build the prototyping circuits matched with Arduino.

lAccess to SOIC SMD pin, supporting the soldering of SOIC chips up to 14pin.

lIncludes a 170-hole breadboard.

This keyestudio sensor shield has extended the digital and analog ports out as 3PIN interface (G,V, S), which can directly connect 3PIN sensor modules.It also breaks out some communication pins of 2.54mm pitch, like serial, IIC, and SPI communication.The shield comes with a reset button and 2 signal indicators as well.Additionally, you can supply the voltage needed to the sensor modules through .

In the experiments, you might often use UNO R3 control board and several sensor modules. If the interfaces of power output is not enough, you may need to add a breadboard and use many connection wires. Is it really troublesome？But now, with this keyestudio sensor shield, you can easily solve that problem. This shield is fully compatible with UNO R3 control board, so you can easily stack it onto UNO R3 for use.

lExtends an Arduino Reset button.
