3 neat ATXmega prototype boards

This time i present three neat prototype boards for Xmega processors, in the Xmega A4 (44pin), A3 (64pin), and A1 (100pin) versions, compatible with all of the models of each family. The PCBs are designed to put with one or both sides in the breadboard, they are small and compact so they doesn’t occupy much space, with on board: PDI programming interface cnnector, USB connector (for devices in “U” version with support for high-speed USB), uSD socket, buttons, which are just a basic add-ons.

USBTiny-MkII SLIM programmer

USBTiny-MkII SLIM programmer (AVRISP-MKII clone) supports all Attiny, Atmega, and Xmega µcontrollers. It has three programming interfaces: ISP, PDI, and TPI. It works with AvrStudio or AvrDude. Small convenient board, contains double direction voltage translator for all interfaces and working from 1,2V, jumper for target chip voltage selection 5V or 3,3V (LDO stabilizer), and status LEDs. The heart of the device is a AT90USB162 controller with hardware USB, so it can provide fast programming speeds.
