 Please bear in mind the current PCB revision is <color #ed1c24>v3.1</color>. This is due to errors found in the early builds (mostly to do with hole sizes). Once the <color #ed1c24>v3.1</color> boards have arrived and been tested, I will upload those photos here.

+So here it is, PCB v1.0 that I have built up. It worked first time with no modification, so I was pretty pleased. The main issue with this PCB was that I used hole sizes that were a little too small on the 40way header, so it was a tight squeeze. I also didn't via all the holes (only the ones connected in the schematic) and for better soldering, I should have done them all.
+\\
+\\
+Both of these issues are now fixed on the v3.1. Why the jump from v1.0 to 3.1? Well there are a few subtle changes, some tracks have been re-routed for tidiness, some resistors moved a little and the outline has been changed to have round corners (no idea if the PCB manufacturer will cut them like this though).
+\\
+\\
+Keep an eye on this page for the v3.1 photos, hopefully by the end of April 2017, depending on shipping (can be 4-6 weeks to come from Hong Kong to the UK).
