The 28-Pin AVR ZIF Breakout provides a convenent way to connect an AVR microcontroller to either an ICSP programmer or a USB-to-Serial converter.
- The power selection jumper controls whether power for the MCU is taken from the USB-Serial connection or the ICSP connection. Move the jumper to the appropriate position.
- The power LED shows when power is available to the board.
- The USB-Serial header allows connection of a serial cable using the common FTDI 6-pin format.
- The ICSP header allows connection of an ICSP programmer such as a USBasp.
- The ZIF (Zero Insertion Force) socket is for your ATmega MCU.
- The ZIF socket release lever either locks or releases the MCU.
- The pin 1 marker shows which end of the MCU is pin 1. Usually there will be a small notch in the end of the IC at the same end as pin 1. Be very careful to place the MCU in the ZIF socket the right way around!
- The reset button allows the MCU to be forced into a reset state.
- The D13 LED is connected to MCU pin 19, which is port B bit 5 (PB5) and also accessed as digital pin 13 when using an ATmega MCU with Arduino software.
