this little guy turns the 8-bit value into hex! it's also configurable: you can flip the digits upside down for when you plug it into the left side of your breadboard. it can also trigger and latch data on the rising or falling edge of the optional trigger pulse, it can be level or edge sensitive, and you can set it to "single shot" capture a single value.
@tubetime Reminds me of the E&L TTL test rigs. Is there documentation on this thingy somewhere?
