DESCRIPTION
Linduino One Isolated
Arduino-Compatible
Demonstration Board
Linear Technology’s DC2026 (called the Linduino
®
One) is
compatible with the Arduino Uno microcontroller board.
Arduino hardware consists of an Atmel microcontroller
with a bootloader allowing quick in-circuit firmware up
-
dates. The software is a simple programming environment
based
on the AVRGCC compiler. This platform is popular
because it is easy to use, both the hardware and software
are open source, and it can be programmed in C. We find
it an ideal way to demonstrate and distribute libraries for
integrated circuits that have digital interfaces such as
Inter-Integrated Circuit (I
2
C) and Serial Peripheral Interface
(SPI). While the Linduino One is Arduino-compatible, it
is not produced by the official Arduino team, and they do
not receive any monetary support from this board. Please,
consider supporting them by purchasing other items from:

The Linduino One adds several features to the standard
Arduino Uno board:
• A 14-pin QuikEval™ connector provides a direct connec
-
tion to a growing list of hundreds of Linear Technology
demo boards, including ADCs, DACs, Power System
Management, RF Synthesizers, System Monitor and
Control, and many others.
• Selectable 5V, 3.3V, 2.5V, 1.8V logic levels and analog
supply on QuikEval Connector
• An LTM
®
2884 provides galvanic isolation of USB data
and power for both safety and noise rejection.
• Auxiliary 7V to 20V power input on isolated side, with
conversion to 5V provided by an LT
®
3973 allowing high
power operation up to 750mA.
