The Keyestudio Sensor Shield is designed to expand the functionality of the UNO R3 control board by providing additional interfaces and power output options. It simplifies connections for sensors and modules, making it ideal for experimental setups and prototyping.

Features
- Compatibility: Works with UNO R3, 51duino, Keyestudio EASY plug Control Board, and Leonardo R3.
- Extended Interfaces: Digital and analog ports broken out as 3PIN headers (G, V, S) for direct sensor connections. Includes serial, I2C, SPI, URF, and APC220 interfaces.
- Power Supply Options: Terminal blocks supply different voltages. Configurable via jumper caps and terminal blocks.
- Built-in reset button.
- Power and D13 indicators.
- Compact design: 57mm × 57mm × 20mm, weight 20.5g.
Specifications
- Breakout all digital and analog ports as 3PIN headers.
- Serial, I2C, SPI communication interfaces.
- URF and APC220 interfaces.
- Voltage supply via terminal blocks.
- Built-in power indicator and D13 indicator.
- Compatibility: 51duino, Keyestudio UNO R3, EASY plug Control Board, Leonardo R3.
Dimensions
- 57mm × 57mm × 20mm
- Weight: 20.5g

Voltage Configurations
When SE is connected with jumper cap:
- Input DC 7V to VCC/GND terminal: V, V1, + pins = 7V
- No voltage input: powered via UNO R3, V, V1, + pins = 5V
When SE is disconnected:
- Input DC 7V: V = 7V, V1 and + = 0V
- No input: powered via UNO R3, V = 0V, V1 and + = 5V
