Remember a few blogs back where we were talking about prototyping boards for Raspberry Pi and similar and I showed a sample board and someone came back and said “Ah but you can get cheaper on AliExpress” – well, I bought one…
Here’s the link – £1.09 in sterling, free postage…. and I have to say… pretty good. Took a few minutes to solder the gold plated connector – holes are PTH and look ok.
So – if you click on the image you might get a larger version… the board came with the connector and nuts and bolts which I managed to lose within minutes of bringing the board into my office. So you get a 5v rail and ground rail on the left. Over on the right there are full length 3v3 and ground rails and a whole line of holes for every pin (other than ground and power as you already have them). The rest are all uncommitted runs.
I have to say, for that price if you’re into tinkering – it’s a winner. Should work with any of the Pi-type boards with the same connector – though clearly some of the IO pins will be wrong on some boards. Very nice – just ordered another one.
