I’m a new user of the particle.
I want to control a relays directly from the digital pins for the particle photon and i want you re feedback guys for this one:
its relay but connected to an electronic board.
it have vcc input and signal input as well as the main current input and output
No I want to buy it and i want to know if anybody use it before with a particle.
I want to control a 12V solenoid by a relays.But when i checked for the relays,The most of them are stronger for particle digital pin.so it will need a transistor to boost the digital pin signal to activate the relay.but the issue was esthetic.
So It will be better If I found a same système(Relay vs Transistor) but on Electronic board.
I'd not power a 3.0-3.3V reated relay coild off of 5V - they would have rated it higher if it was safe
The control pin on such relay boards usually comprises an input transistor which won't pull much current from the controler pin but only switches the supply voltage. The main thing you'd need to "worry" about is whether the 3.3V level is enough for the transistor to reliably switch.
