There are two versions of the Triac Nanoshield. This is the 50mm heatsink version, supporting currents up to 2.5A. Check our store for the smaller 25mm/2.5A version.
This module was designed to connect directly to the AC grid power, and its misuse might cause ELECTRIC SHOCK and FIRE. Only use this module if you already have prior experience with mains AC circuits, and carefully follow the safety recommendations at the bottom of this page.
The Triac Nanoshield can be used to control appliances connected to the power grid in 127V or 220V AC (alternating current) using the I/O pins of your Arduino. Is is ideal for applications like:
There are 4 options of I/O pins to activate the triac (D3#, D5#, D6# e D9#), which can be easily selected using jumpers on the board. In case these four options are not enough, there are 7 more options that can be selected by solder jumpers at the bottom side of the board (D2, D4, D7, A2, A3, A4 e A5). The triac is activated when there is a high logic level on the correponding I/O pin, and deactivated when the there is a low logic level on the pin.
The triac is activated via an optocoupler and the triac lead that is kept in contact with the heatsink is internally isolated. This keeps the AC voltage away from the microcontroller and other DC circuits.
