Solid state relay expansion board for Arduino Nano - AC/DC configuration
Expansion board (shield) for the Arduino Nano with eight interchangable solid state relays. The relays are wired in an AC/DC configuration and can be used to control both AC and DC loads. The PCB includes space for a snubber network and transient voltage suppressor (AC configuration) or a flyback diode (DC configuration).
Arduino firmware for controlling the relays for sending comands to Arduino are availabe here https://bitbucket.org/iorodeo/
Note, there are two variants of the firmware:
iorodeo/nano_ssr_software/src/ cc9b8cdfc9647ff15729a89bb3abd6 2c4da9521f/basic?at=default. The basic firmware enables you to send command to turn the individual relays on and off. As well as to turn all relays on and off at once.
iorodeo/nano_ssr_software/src/ cc9b8cdfc9647ff15729a89bb3abd6 2c4da9521f/pulse?at=default. The pulse firmware enables you to pulse the relays at a use specified frequency and number of repetitions.
