INTRODUCTION
MOD-IO is a small but powerful development board who let you control 4
optoisolated input and 4 relay outputs - with this features is possible to turn on
and off almost any electronic device at home. The board has UEXT_FEMALE
connector which allows you to communicate with a PC and UEXT_MALE
connector where you can connect other Olimex board with UEXT.
The MOD-IO project is fully open software and open hardware. The customer has
full access to the documentation of the board including schematics and board
design.
The main idea of MOD-IO chain connection is to extend:
- isolated relay outputs
- isolated digit inputs
- non isolated analog inputs
- non isolated digit inputs/outputs
using UEXT male/female connector. So the MCU interfaces (I2C, SPI, UART) from
all chain boards are connected in parallel.
Note that if you want to connect more than 1 MOD-IO board then on the interface
bus (I2C or UART or SPI) has to have only one Master device. The other devices
have to be Slaves.
For example: if UART interface is used - the master will send a string with Slave
address and command. All Slaves will listen UART bus through RXD line while
all Slave TXD lines are inputs. So when the address is recognized from the Slave
device, the one will answer as it will force TXD pin like output but immediately
after command answer is finished the Slave TXD pin must be initialized like input.
The same principle can be used for other interfaces (SPI or I2C).

ELECTROSTATIC WARNING
The MOD-IO board is shipped in protective anti-static packaging. The board must
not be subject to high electrostatic potentials. General practice for working with
static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS
Cables:
Hardware:
Software:
The cable you will need depends on the programmer/debugger you
use. If you use AVR-PG1, or AVR-JTAG, you will need RS232 cable, if
you use AVR-PG2, you will need LPT cable, if you use AVR-USBJTAG, AVR-ISP500, AVR-ISP500-TINY, AVR-ISP500-ISO, AVR-ISPMK2 you will need 1.8 meter A-B USB cable.
One of Olimex programmers/debuggers – AVR-PG1, AVR-PG2,
AVR-ISP500, AVR-ISP500-TINY, AVR-ISP500-ISO, AVR-JTAG, AVRUSB-JTAG, AVR-ISP-MK2 or other compatible programming/debugging
tool.
Make sure to check if the above programmer/debugger is supported
by the IDE you are going to use.

IN1, IN2 IN3, IN4
Please note that the opto-isolated inputs IN1, IN2, IN3, IN4 in earlier revisions were able to receive
signals in the 3V to 6V range. R27, R29, R31, R33 were 330R and R28, R30, R32, R34 were R4.7k.
We have now adjusted the values of the resistors in that part of the schematic in latest revisions to
allow higher voltage input in the 3.3V-24.0V range. R27, R29, R31, R33 are now R3.9k and R28, R30,
R32, R34 are now R47k

For product support, hardware information and error reports mail to: [email protected]. Note that
we are primarily a hardware company and our software support is limited.
Please consider reading the paragraph below about the warranty of Olimex products.
Warranty and returns:
Our boards have lifetime warranty against manufacturing defects and components.
During development work it is not unlikely that you can burn your programmer or development
board. This is normal, we also do development work and we have damaged A LOT of programmers
and boards during our daily job so we know how it works. If our board/programmer has worked
fine then stopped, please check if you didn't apply over voltage by mistake, or shorted something in
your target board where the programmer was connected etc. Sometimes boards might get damaged
by ESD shock voltage or if you spill coffee on them during your work when they are powered.
Please note that warranty do not cover problems caused by unproper use, shorts, over-voltages, ESD
shock etc.
If the board has warranty label it should be not broken. Broken labels void the warranty, same
applies for boards modified by the customer, for instance soldering additional components or
removing components - such boards will be not be a subject of our warranty.
If you are positive that the problem is due to manufacturing defect or component you can return the
board back to us for inspection.
When we receive the board we will check and if the problem is caused due to our fault and we will
repair/replace the faulty hardware free of charge, otherwise we can quote price of the repair.
Note that all shippings back and forth have to be covered by the customer. Before you ship anything
back you need to ask for RMA. When you ship back please attach to it your shipping address, phone,
e-mail, RMA# and brief description of the problem. All boards should be sent back in antistatic
package and well packed to prevent damages during the transport.
