They're not actually our product, we're just a re-seller for them. But I see your point about the headers - would make more sense for them to be fitted on the reverse side. I'll feed it back to the manufacturer when the opportunity arises.

Thanks for that.
I had guessed they were bought in.
They're quite good quality PCB-wise.
I have managed to de-solder all the headers and display sockets. The displays are soldered straight in now and are a little tidier. I reversed the male headers and added offset (0.05") pins to bring them into line with 0.1" perfboard.
With the Nano onboard, it makes quite a useful counter, even at very fast count rates.
For what it's worth, I always use the StateChange example from the Arduino IDE to process button or digital changes. Of all the examples, this one seems the most reliable

Hi,

Please, where can I find a drawing with precise dimensions including the PCB holes diameters and positions?

I'm asking because I would like to request a quote for laser cutting an acrylic mask.
(Or in some fireproof material... no idea yet if they offer any such alternatives.)
