Zipit Z2 Breakout v1

It’s official, 30 Zipit breakout boards are here. You can order yours in the shop I’ve setup. My previous posts about the design process have some info about the board’s functionality and some issues that needed fixing. This post is intended to bring all the info to one spot and explain how it functions. Any new information will be added to this post.

Wifi Enabled Outlet with VoCore

We have an older Mr. Coffee without all that newfangled technology like a clock and timer which means getting out of bed to start the coffee pot. How can one turn on a coffee pot without leaving the warmth of cozy sheets? Add a VoCore, some LED’s and relays to a surge protector/USB charger, that’s how.

Z2 Breakout Testing Part 2

After fiddling around with the two breakout boards I’ve assembled, I think I’ve got everything the way I want it. I’ve made some new useful changes as well as fixed the issues I described in my previous post. The remaining parts needed for the Z2 Breakout relay header arrived today and all is working there. I also did some current testing tonight and thought I’d share the numbers.

3.3V to 5V Boost Converter for Low Power Projects

Quite a while ago I built a USB adapter for my Zipit based on the Texas Instruments TPS61240 boost converter IC. It’s a small chip and only needs 3 external components to function. The ouput current is limited to 400-450mA but it runs most low power USB devices just fine (flash drive, mouse, webcam). It also has a wide input voltage range of 2.3V-5.5V. This makes it a great boost converter for low power / battery operated projects so I decided to design a breakout board for it.
