BTW, I’ve been working with ezSBC for over three years now and every daughterboard I’ve ever made has one of their regulators integrated well, except the one hand-etched prototype in my basement that has a muRata regulator.

On the other hand, the output ” 1″ level of 74LS latch does not go to Vcc. Add to watch list. Add to cart to save with this special offer. Parts Digital Photo Cameras. See terms – opens in a new window or tab. Also, inspected the board visually to check for broken or cracked solder joins.
