AVR-HV2 programmer is designed as an Arduino Mega shield. Dimensions of the AVR-HV2 are similar to the Arduino Mega board. It can be powered using a power source connected to the Arduino Mega board. The suggested power source for this programmer is a 12V 1A DC power adapter.
The control software of this programmer is design to work on both Windows and Linux operating systems. It supports the import and export of memory data in the Intel hex file format. The communication link between the programmer and the control software is established through the USB port.
The current firmware and control software of this programmer supports most of the generally available AVR MCUs which including ATmega8, ATmega328, ATmega32, ATmega16, etc. The AVR MCUs with extended addressing modes are currently not supported.
The PCB board used in this project is sponsored by the PCBWay. PCB of this project can directly order from PCBWay through this link.
This is an open-source hardware project. All the design files, firmware, documentation and control software source codes are available at GitHub repository.
I added a boost converter on my High Voltage Serial Programmer. That way I don't need a separate 12V power supply.
The values of R2 and R4 seem a bit low to me. Is there a specific reason for it, that I'm missing?
