But > the 24FJ64GB002 that comes with the MicroStick is 0.25%. Interesting. I am hoping to play with some of the WS2812 LEDs (with built in controllers), which have a bit of an oddball timing requirement, making them tricky to drive on a micro that has a bunch of other tasks to perform. I'm hoping that by using a chip with a high enough instruction clock I will be able to do some useful work while still driving the LEDs.

They're small enough that I can take them with me, and as I sometimes do development while traveling, that's a huge bonus. Normally I just use a board from a previous project when I'm trying things out, but as I'm looking to get into higher level PICs, I don't have anything like that yet. Since I want to mess around with them on these projects, I wanted to get a general purpose board that I can play with. I don't think I'll end up using a proto-board, I'll most likely jumper whatever dev board I end up with over to one of my boards. > I'm just a hobbyist these days, so I don't need anything fancy. I'm not looking for too fancy either, just something that works!
