DEMO MANUAL DC2026A
Linduino One Isolated
Arduino-Compatible
Demonstration Board
Description
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.Thesoftwareisasimpleprogrammingenvironment
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
The Linduino One adds several features to the standard
Arduino Uno board:
