Thank you for sharing a nice circuit to upload the hex file to an AVR microcontroller through SD card. I designed a PCB and before uploading to GitHub, I would like to share you the circuit diagram. Can you spare a time to verify the circuit I an using?
Please follow the link for the schematic (https://github.com/kapil-iitk/AVR_SD_Programmer/blob/master/AVR_Prog.pdf). In the schematic, I am using resistor based voltage divider network for the 5V to 3.3 V conversion (for SD card to AVR interface). Can I remove the reset switch? Also, can I use internal oscillator (8MHz) so that I can remove the crystal oscillator?
Thank you for your time.
