NOTE: the beaglebone black GPIO pins are only rated for 4 to 6mA per pin, which means it is essential to choose a triac with a guaranteed trigger current of 5mA such as the MOC3023 If you instead get a part with a 15mA guaranteed trigger, you may end up with customers who don't get their product even though they paid for it, on days when the temperature or phase of the moon is wrong. That would be really bad. | |||
ALSO: there are two physical versions of the through-hole part. One is "Dual-in-line" and the other is "Wide lead spacing". The former fits in the sockets on this board, at standard DIP width of 0.300" track width, while the "Wide lead spacing" would need to be bent to fit a normal socket, on this board. You don't want to be stuck bending 240 pins for this project because you bought the wrong part, do you? | |||
