USBtinyISP Programmer

  • PROJECT

A few weeks ago, I was commissioned to build a programmer for the AVR8 series. I used the design found on the Centro de Microelectrónica website, which is a lab belonging to the Universidad de los Andes. After reviewing the schematic and PCB on the website, I decided to make some changes to the layout of the PCB.

The schematic remained unchanged. For the PCB, I rearranged the components for a longer design, similar to the PICKit2 ICSP, by placing the USB connector on one side of the board and the ISP connectors on the opposite side. I also added the pin names as silkscreen (MISO, SCK, RES, VTG, MOSI, and GND) to make it easier to identify and connect the signals.

The programmer supports the following microcontrollers:
