A Raspberry Pi Zero is down to a price and size where it’s just begging to be integrated into your projects. Unless, that is, if your project involves a lot of 5 V equipment. Then it’s just begging to be fried.
[David Brown] solved this problem by breaking out pins with level converters. He used flat-flex cable and some pin-headers. While he was at it, he added a full-sized USB port and power headers. (Extra hack points are awarded for connecting the USB to the board through pogo pins.)
The board is now in its third revision, having sacrificed a Pi Zero and learned why many boards include over-voltage protection in version 2.0. It’s a neat and tidy solution to the problem of interfacing the Pi with a non-3.3 V world.
We saw a ton of Pi Zero add-ons when it was new. No doubt some of this was due to our Pi Zero Contest, but we bet a lot of it was also driven by need: the need for VGA out, or quadcopter control, or just lighting up power-hungry LEDs. You Pi Zero is only as versatile as you make it.
