Had chance to assemble the prototype 2 board this evening. I made my solder stencil using the Silhouette Portrait cutter and mylar sheets (see which worked amazingly well. Hand assembling the components is definitely fiddly, and i think for the next batch I'm going to buy slightly bigger capacitors because these ones are way too small for me (0402s). But, once done I popped the board into the T962 oven, baked at gas mark 10, and voila! Popped it into the programming rig, flashed the latest firmware, and everything works!

Just added the battery to the back, and the power management and boost converter appear to be ticking along correctly

So - pretty pleased and, as ever, slightly shocked that it all works.
