a simple pcb with a few sockets to program attiny/atmega microcontrollers from an arduino micro used as isp programmer

all steps below include the use of the Arduino IDE: https://www.arduino.cc/en/Main/Software (1.6 or higher).

Add the following URLs in File > Preferences for the setting Additionals Boards Manager URLs:

If you want to program a Non-P version (for example an ATmega1284 instead of an ATmega1284p), you need to open your avrdude.conf and add a Section like below. The non-P versions are essentially the same as the P versions and they can be cloned. The plain 644 is supported out of the box (with avrdude 6.0.1).

#------------------------------------------------------------
# ATmega1284

part parent "atmega1284p"
    id               = "m1284";
    desc             = "ATmega1284";
    signature        = 0x1e 0x97 0x06;
  ;

# ATmega324

part parent "m324p"
    id               = "m324";
    desc             = "ATmega324";
    signature        = ???????????????????????;
  ;

#------------------------------------------------------------
# ATmega164
#------------------------------------------------------------

part parent "m164p"
    id               = "m164";
    desc             = "ATmega164";
    signature        = ?????????????????????????

• plug in your arduino micro and connect it to the pc
• start up the arduino IDE
• connect your arduino micro
• open up the programmer sketch: File > Examples > ArduinoISP
• change the line #define RESET SS to #define RESET 10
• select Tools > Board > Arduino Micro
• burn the programmer to your Arduino Micro with File > Upload
• verify the RDY led is pulsing
• select your micro as programmer Tools > Programmer > Arduino as ISP

once this is done, you can program as many chips as you want

• plug in the chip to program (make sure there's just 1 chip on the board ;))
• open the sketch to program to the chip
• select the correct target board through Tools > Board > ...
• burn the sketch using File > Upload using Programmer
• the PRG led should light while the program is written
• you're done!
