Fully functional boards, although probably not at 1A per channel. These are the leftover boards from the first set of home etched boards we made as prototypes to test the viability of the VO2223A chip for SSR use. These are pre-drilled, single sided bare boards. You can own a piece of history for only a buck -- includes shipping, of course. Five bucks gets you all 5 of them. Remember, the DirkCheapSSR revolutionized the pricing of working SSRs by providing a really low, rock-bottom price of less than $1 per channel. And now there are literally many thousands of DirkCheapSSRs out in service -- you can own part of the first 8 ever made!
