Using the overlay you just bought, you can flash your own by soldering only 3 wires as shown here.
The instructions below mention Herald's USB board which is no longer available, and also mentions
the crystal and capacitors used for the optional stopwatch feature. But if you flash the calc.bin
image you don't need the crystal/caps so you can do it with only 3 wires.
