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.

Universal Logic Analyzer Board

I think i don’t need to convince anybody, how great device the logic analyzer is. This one leaves far behind every old-fashion LPT versions, as well as AVR with external RAM based ones. Depending on chosen PC application (the real analyzer part, actually), it can collect for an example, up to 24 millions of samples per second from 8 channels at the same time, and the buffer capacity is just our PC free RAM space…

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.

µProg – tiny, fast, portable AVR programmer with SD

One of a kind, portable AVR programmer! Helps wherever you need to update the device firmware, where target device is in a hard-to-reach location and you can’t (or don’t want to) bring your laptop with a bunch of wires with you. Trivially easy to use, super cheap to make, super small, super fast, uses SD cards…

Kolorofon na USB

This project is a remake of an old discolights pod. Original 24V 5W bulbs are changed to 230V 40W with E14 thread. Original driver board has non-typical signal input. This driver is based on the FT245RL chip, a USB-LPT converter – so you can use it with PC applications such as discolitez. Low voltage part is supplied directly from the USB so there is no need to to use any transformer…

Miniature LCD driver – LCD2USB + frontpanel

Miniature version of LCD2USB device, a lcd driver connected to usb port. Because the original pcb was too complicated for home-make, i have projected new pcb – all parts is surface-mounted, pcb width is width of 16 pin connector which is fit exactly behind lcd. I used mini-usb connector, ATMega8 in TQFP package, and some of other SMT parts. As pcb is modified, it need modified firmware available for download below. Rest of description is available on original autor site.
