AVR ZIF programming socket

Overview

This adapter board provides a simple way of connecting an In-System-Programmer to an AVR microcontroller in DIP format using a zero insertion force (ZIF) socket. It is intendet for fast prototyping, initial bootloader flashing and testing without the hassle of faulty breadboard jumpers or unnecassary connection errors.

Features

The programming socket provides support for all AVR microcontrollers available in the prototype friendly DIP format supporting In-System-Programming (ISP). Furthermore the board supplies connections to 8Mhz crystals, thus the AVRs will also be programmable with the fuses set for an external crystal from 3-20Mhz, making it ideal for programming fuses and flashing programs for circuits utilizing external crystals.

How to use

Put your AVR in the ZIF socket by aligning the IC mark for the first pin (the dot and/or indentation) with the lower edge of the ZIF socket (near the ZIF socket lever). Afterward, find your AVR name in the list below and connect your In-System-Programmer to the corresponding ISP header (see AVRs per ISP header).

AVRs per ISP header

ISP header 1 is next to the ZIF socket lever.

  • ISP header 1: ATtiny12 / ATtiny13 / ATtiny15L / ATtiny25 / ATtiny45 / ATtiny88
  • ISP header 2: ATtiny24 / ATtiny44 / ATtiny84
  • ISP header 3: ATtiny2313 / ATtiny4313
  • ISP header 4: ATtiny26 / ATtiny261 / ATtiny461 / ATtiny861
  • ISP header 5: ATtiny44 / ATtiny88 / ATmega8 / ATtmega48 / ATmega88 / ATmega168 / ATmega328
  • ISP header 6: ATmega162 / ATmega8515 / ATmega8535
  • ISP header 7: ATmega16 / ATmega32 / ATmega164 / ATmega324 / ATmega644 / ATmega1284 / ATmega64RZAV
