About
My name is Kevin Darrah and I have a design services company called KD Circuits http://www.kdcircuits.com
One of my passions is teaching electronics on YouTube: https://www.youtube.com/user/kdarrah1234
A lot of the projects and concepts I talk about in those videos are based on my own designs, which is why I'm here on Tindie to make them available for sale.
Thanks for stopping by!
Kevin

Swiss Army Knife for Serial Debugging
For FTDI USB-SERIAL Converter - 5V/3.3V
With these devices, the ability to flip easily between 3.3VDC and 5 VDC logic as well as supplying and not supplying power has saved me headaches and allowed for simpler dev and test set ups. It's odd, but about half of my designs have PICs using a 5V supply and the other half is MSP430 and a whole bunch of M0/3/4 core ARM processors. Throwing a serial link or 2 on a board is automatic at this point, and I always have 1+ of these little guys handy.
One last note: if serial converters are understood, then documentation is not necessary. The board itself has enough information on it to pluggin and get chuggin.
