Specification sheet so the various sensors can be found in the below attachments as well as the Gerber files and Fritizing files for the shield.Ģ. It also has a USB power out to power other USB devices such as an Arduino or Particle, etc. I have also included my patended I2C micro sensor inputs shields, which can be either a (a) power sensor, (b) accelerometer, (c) altimeter (d) humidity temperature sensor. It is good for 5 Amps, which is more than enough seeing that higher loads will require another contactor to be driven from the relay. It not only converts 120/240 to a useable DC voltage, it also has a DC input good for 30 volts DC and a relay that is activated from D6 that can either be used as a 120V relay or a DC relay depending on how it is powered. As you can see from the included images, I used silicone to isolate the power pins on the underside of the shield. Be very careful not to come into contact with the high voltage side of the shield. TEST THE SHIELD BEFORE YOU PLUG IT INTO the Expansion Shield using a voltmeter to ensure that 5 volts DC is the output on the VIN pin of the shield. You should only have the power plug plugged in if it is inside a plastic or insulated box and ready to be tested and/or completed.
Do not work on the Shieldwhile it is plugged into power. You can also be seriously hurt if you don’t use proper work and safety ethic. These voltages could be deadly and or cause a fire if you overload the relay or solder it wrong. Before starting this project you should be aware that you are hooking 120/240 volts AC to your shield.
