We designed the PCB for this shield in the Elektor Lab, all parts for building a prototype arrived today. Soldering the 3.3V <-> 5V level translators we selected (MAX3378EEUD+, TSSOP-14) will be a challenge, but -although we have a reflow oven- I'll give it a try with the hot air rework station first. I'll post some photo's when it's ready.
