A few years ago I ran a Kickstarter for a prototyping board for the Pi:
https://www.raspberrypi.org/forums/view ... 5&t=103643
It was successful, and after selling the first production run I was talked into making some more, and most of them sold, more and more slowly...
There are fewer than 20 left, but they're sitting on the shelf and I need to clear them out. So I've reduced the price to clear - only US$20, plus shipping - well below cost! They have to go, and this time I definitely won't be making any more. So if you want to nab a really useful prototyping board at below cost , here's your chance!
So what do you get?
* The board brings out all the Pi's 40 GPIO pins to a row of clearly-labelled headers, next to a nice big breadboard that you can build your circuits on.
* So that those circuits don't tax the Pi's power supply (especially the 3.3V rail, which on the Pi is pretty limited), the board has its own USB power connector, and a 3.3V regulator to power your circuits. And you can feed that power back to the Pi, as well, if you like.
* The USB port also acts as a serial console connection, through an on-board FTDI chip. Really handy for debugging!
* There's also an analog to digital converter chip (the well-supported MCP3008), to make up for the Pi not having any analog inputs. And a trimpot to use as a simple analog input for your projects.
* It includes a couple of pushbuttons and four LEDs, for your basic digital I/O needs.
* And finally, there's a cute drawing of a wombat in the upper corner! What more could you want?
Excellent value - I literally can't build them for this price. So grab one while they're still available!
Where from, you ask?
