DEMO MANUAL DC2026A

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.

• 

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.
