This shield is compatible with most types of Arduino boards that support the standard header layout including Uno, Leonardo, and Mega. It provides a convenient way to connect various sensor modules, servo's, or I2C LCD displays without the need for soldering.
Please note: I2C interface compatible with Uno only. When connecting multiple servos please check power requirements of each servo.
This shield is compatible with most types of Arduino boards that support the standard header layout including Uno, Leonardo, and Mega. It provides a convenient way to connect various sensor modules, servo's, or I2C LCD displays without the need for soldering. The shield has the following features:
6 x Buckled 3 pin analogue connectors providing connections to Analogue pins A0 to A5, GND and 5V
1x Buckled 4 pin serial I2C / UART interface (selectable via on board jumpers) providing convenient connection to serial or I2C sensors or displays.
12x Servo headers proving access to digital pins 0 to 13 with VCC and GND power connections.
6x Aux headers providing access to analogue pins A0 to A5
Serial I2C / UART jumper selection
Reset button
Standard Arduino headers for adding additional shields.
Please note: I2C interface compatible with Uno only. When connecting multiple servos please check power requirements of each servo.
