## Summary description

The Arduino TSX00003 Proto Shield is designed for prototyping with Arduino boards. It features a breadboard area for easy circuit assembly, multiple I/O pin connections, and compatibility with Arduino TSX00003. Ideal for developers and hobbyists looking to create custom projects with ease.

## Long description

The Proto shield Arduino TSX00003 is an expansion board designed for prototyping with Arduino MKR and compatible boards. It provides two relays (RELAY1 and RELAY2) controlled by digital pins 1 and 2, screw terminal connections for analog inputs A1–A4, I2C lines, and power supply lines, plus a prototyping area for building custom circuits.
Advantages
The shield integrates two relays on a compact board, simplifies wiring with screw terminal blocks for analog inputs and power, and exposes I2C and digital control pins for straightforward integration with MKR-based projects. Its prototyping area supports quick assembly and modifications without soldering or extensive wiring.
Suitable for
 Prototyping MKR-based control circuits that require switching of external loads
 Small automation projects where two relay channels are sufficient
 Educational projects and rapid testing of sensor-actuator interactions via A1–A4 and I2C
Key specifications
 Compatible boards: Arduino MKR and compatible form factor
 Relay channels: 2 (RELAY1 on pin 1, RELAY2 on pin 2)
 Connections: screw terminals for A1–A4, I2C lines, and power supply
 Prototyping area: breadboard-style space for custom circuits
 Manufacturer MPN: TSX00003, EAN: 8137470205276
How to use
Place the Proto shield onto an Arduino MKR or compatible board so that the pins align. Use digital pin 1 and pin 2 to control RELAY1 and RELAY2 respectively from your sketch. Connect sensors or analog signals to the screw terminals for A1–A4 and use the I2C lines for compatible devices. Provide appropriate power to the shield through the host board. Assemble additional components on the prototyping area and wire them to the required pins using the screw terminals or jumper wires.
Usage recommendations
Confirm relay voltage and current ratings in the relay datasheet before switching external loads. Use proper isolation and follow safety practices when working with mains or high-voltage circuits. For stable operation, ensure the host board supplies sufficient current for both the relays and attached devices.
