The problem: you need the chip to figure out if your code actually works. And you also need the LEDs to see what’s going on – if at all. You could use a logic analyzer, but that is overkill. Just looking at the LEDs is a much more suitable way. Your code might have insidious bugs, or the datasheet might simply be crap / outdated / obsolete – of course without your knowledge. BUT you surely don’t want to fight wires, at least not during the coding / debugging phase. All you need is the chip + onboard LEDs as indicators.
Later, if everything works, you may want to (should actually!) test the chip with the real things. And this board allows for that as well. Pull a jumper and you can connect external LEDs with a supply voltage higher than VCC – without blowing up the onboard LEDs (reverse biased in that case).
