This is a nifty little GPIO reference board that slips over the GPIO pins, is impossible to put on the wrong way and attaches to a keyring, if that’s what you want. I spotted this months ago and I’m pleased to say it’s now available to buy!
You can get it in the UK at Pi Hut. For the next couple of days it’s only £2.99 (plus postage). It’s a bit geeky, yes, but we’re kidding ourselves if we think that’s a problem for Pi enthusiasts 🙂
