Arduino Zero using a xQFP80 +50 Protoboard


Tom Keddie shared his Zero project using a xQFP80 +50 Protoboard:

I need more processing power than an AVR for an upcoming project so I ordered an Arduino Zero to take a look at the SAMD ARM processors. Unfortunately my son coveted the box it came in, once the two were separated the Zero was never seen again. I had separately ordered the processor part, I realised I could build a Zero using a spare DP xQFP 50/80 prototyping board.
The schematic is fairly simple, doesn’t even need an external crystal. I was extra pleased when I realised the 1.27mm header fit the SOIC pattern on the board.

Via the project log forum.

xQFP protoboards are available in 0.50mm, 0.65mm, and 0.80mm+0.50mm for $10.
