AVR-HV: High voltage programmer for AVR MCUs

Description

AVR-HV is high voltage parallel programmer for Atmel AVR series microcontrollers. AVR-HV allows programming, reading, verifying and configuring AVR microcontrollers with its high voltage programming interface and it connected to PC using USB interface.

Compare with other high voltage programming options like Atmel STK500, this programmer is simple to build, less-expensive and also easy to use with GUI application over USB interface.

Current version of AVR-HV support ATmega series AVR microcontrollers, but it can also be used with ATTiny microcontrollers which having high voltage parallel programming (HVPP) interface. To introduce new devices, only the configuration file need to be change and no source code changes are necessary.

Details

AVR-HV USB programmer is based on Microchip's PIC18F4550 microcontroller and the main reason to select this microcontroller is its built-in USB functionality. Compiled version of firmware for this microcontroller is available at file download section of sourceforge.net project page.

Recommended supply voltage for AVR-HV programmer is around 18V - 25VDC. Use 1A - 1.5A regulated power supply to drive this system.

For USB connectivity use standard 1.5m shielded USB data cable.

Programmer software of AVR-HV is available to download at sourceforge.net project page. There are no any configuration, framework installation or driver installation is needed for AVR-HV programmer.

PCB of AVR-HV is available to order at OSH Park.

This project is an open source hardware (OSHW) project. All the project files, source codes, original schematics, PCB designs and compiled binaries are available to download at http://sourceforge.net/projects/avrhv/

Very nice.

Have you built the PCB version yet?

Are the PCB files OSHpark compatible?

Are you sure? yes | no

Thank you very much for the feedback!

PCB is not yet build and waiting for the materials (mainly a double sided copper board).

I didn't upload BRD file and check the compatibility with OSH Park because most of the times I build PCBs myself.

Are you sure? yes | no

You might want to check that once you have completed the prototype board for yourself because I'm pretty sure others will want to build one of these for themselves though some may want to have the boards built for them.

I think it's worth the effort to make it compatible with the commercial PCB houses early on as I think this may end up being more popular than you anticipated. ;')

Are you sure? yes | no

I add project to OSH Park. Link is: http://oshpark.com/shared_projects/nsvkzqgX

Thank you for the tip ;)

Are you sure? yes | no

Awesome, thanks.

Like I said, I think a lot of people may want one of these and, in North America at least, OSH Park is pretty popular.

Are you sure? yes | no

Yah... in sri lanka most of the times we build PCBs ourself. :)

Are you sure? yes | no
