4.2 Serial programming of the microcontroller

The table below details the proper connections needed to establish between ICSP programmer and
the board's microcontroller (ATtiny85) or to the GPIO connector (e.g. you don't need to remove the
microcontroller from its plastic socket, you can lead the proper signals to the GPIO connector of
ATtiny85).
To establish the connection below you would need at least 6 jumper wires (male-female). If you
connect the ICSP programmer tool to the GPIOs ignore the "TINY85" column in the table. If you
connect the ICSP programmer tool to the TINY85 directly (or via a socket) ignore the "GPIO
connector name" column.

How to determine first pin of the above connectors and interfaces – the ICSP programmer should
have a mark on the connector for its first pin (or the cable leading to the connector would have a
different color on the side of first pin); the TINY85 has a dot that shows which pin is the first one;
the GPIO connector has the names of the pins printed on the top of the board.
If your AVR programmer has only 10-pin ICSP you can convert it to 6-pin ICSP following the
schematic below:
