The DACIO 300 series modules are powerful, ultra low power consumption, microcontroller (MCU) based PC interfacing RS232 IO boards.

Works with Raspberry PI as IO expansion (with analog input) or with Arduino expansion (providing enhanced / precision A/D inputs).


A single RS232 IO board provides two 8-bit digital input/output ports and up to 8 analogue input channels
to computers equipped with a spare RS232 COM port or via a USB to serial converter such as item 2455 or 2327.

Each I/O is individually configurable.
Tried and tested, ultra reliable, easy to use communication and control open protocol.

The DACIO 303 features 8 10-bit A/D and a high speed 115.2kbps serial interface with 3.3V compatible I/O.

UK manufactured and tested & Lead free / RoHS compliant.

Ultra reliable, commercial strength open ASCII protocol.

Industrial strength ESD protection on high speed RS232 interface.

Free software and terminal program

The advanced design features unmatched power and ease of use at a
budget price. These PC interfacing RS232 IO boards are useful for applications
requiring a serial to parallel (and parallel to serial) converter.

It is ideal for use in computer controlled systems, for digital/analogue data
acquisition, robotics, automatic testing equipment, process control or
for experimental and educational purposes.

This RS232 IO card features industry standard RS232 line drivers.
Baud: 9600 and 115200 bps - others available on request.

Flexible and easy to remember bit, byte or 16-bit instructions.
Full (but suppressible) error reporting. Two status LEDs.

Quickstart guide, default settings, LED demo and powerful trace
feature gets you up and running in minutes! Intelligent on-board micro
communicates with a Terminal program on the host computer
allowing you to run demos or try out all the features by typing
commands manually.

Simple module configuration.
