Description: The Intel® Edison is an ultra small computing platform that will change the way you look at embedded electronics. Each Edison is packed with a huge amount of tech goodies into a tiny package while still providing the same robust strength of your go-to single board computer. Powered by the Intel® Atom™ SoC dual-core CPU and including an integrated WiFi, Bluetooth LE, and a 70-pin connector to attach a veritable slew of shield-like “Blocks” which can be stacked on top of each other. It’s no wonder how this little guy is lowering the barrier of entry on the world of electronics!
The GPIO Block is a simple breakout board to bring the GPIO from the Intel® Edison to the user. Bread board friendly, the GPIO Block provides access to all basic GPIO, PWM, and UART2 pins. All GPIO is level shifted to a selectable 3.3v or VSYS. The GPIO add-on also provides access to all three power rails found on the Intel® Edison. 3.3v, 1.8v, VSYS, and GND are accessible for bread board prototyping. Note: Since the level shifting is accomplished through a auto direction sensing translator, driving high current components (Such as Relays, Motors, and high power LED’s) will require an external switch. See the Hookup Guide to learn more.
If you are looking to add a little more stability to your Intel® Edison stack, check out this Hardware Pack. It will provide you with increased mechanical strength for stacking Blocks on your Edison!

I bought this to interface an ADA Fruit OLED display to my Edison via the Edison breakout board from intel. The 2 issues I had were: a) This GPIO board was just a little too big to fit onto the break-out board. The PCB hits the power input connector on the breakout board. b) It turns out that you only need to send info TO the OLED display (no need to use MISO signal), so I was able to have it work directly from the 1.8V Edison I/O without level shifting.
I was able to snip off a corner of this PCB with dykes, then attach it to the Edison and breakout PCB, and toggle the IOs as a test.
This is a good product. Very helpful since it has the level shifters on board to shift up the 1.8V levels to the 3.3V levels. I used this part in my christmas video on youtube. Check it out at the following link. https://www.youtube.com/watch?v=wWiA2SnxU-I
I tried to use this to connect to a relay. It worked fine just by testing it between the 3.3v and GND. But connecting it to one of the GPIOs does not work. Reading the data sheet on the TXB0108, it seems the max output current is 50mA (from my understanding). I don’t get why no one is making a small GPIO breakout that can do up to 5v and can handle an equiparable power output to an arduino board.
This is a good product. Very helpful since I had problems connecting an GPS module true other level shifter types that did not work. This has the level shifters on board to shift up the 1.8V levels to the 3.3V/VSYS levels.
