CHAPTER 2: SETTING UP THE MOD-IO BOARD

2. Introduction to the chapter

This section helps you set up the MOD-IO extension development board for the first time. Please

consider first the electrostatic warning to avoid damaging the board, then discover the hardware and

software required to operate the board.

The procedure to power up the board is given, and a description of the default board behavior is

detailed.

2.1 Electrostatic and electrical polarity warning

MOD-IO is shipped in a protective anti-static package. The board must not be exposed to high

electrostatic potentials. A grounding strap or similar protective device should be worn when

handling the board. Avoid touching the component pins or any other metallic element.

When connecting other electrical devices to the MOD-IO board make sure that they have equal

electrical polarity. This usually occurs in setups where you need to use more than one power supply

unit. If you have such a setup make sure different power supplies are connected to the same

electrical source (to the same utility power socket).

In rare cases different polarity might cause hardware damage to one of the boards in your setup.

2.2 Hardware requirements

In order to set up the MOD-IO optimally one or more additional items may be used. They might be

generally placed in three categories:

Required – items that are needed in order to achieve minimum functionality;

Recommended – items that is good to have in order to be able to interact with the most important

of the features of the board;

Additional – items that provide access to additional features or expand the features of the board.

Required items:

- Power supply unit that is able to provide (6V-20V) AC or (8V-30V) DC

Recommended items:

- An ISP programmer or a JTAG debugger – if you wish to modify the firmware you would need a

way to upload the binary code to the board; in case you wipe the memory accidentally or you need

to replace the main microcontroller you would also need such a tool.

Please note that Olimex has a few low-cost programmers supported both in Atmel studio and in

AVRDude.

Additional items include:

- Jumper cables – comes in handy when you want to connect something to the MOD-IO or when
