Linear Technology DC2294A Linduino Shield Manual

DESCRIPTION
The DC2294A Linduino™ Shield is an adapter board enabling
use of Linduino PSM (Power System Management) soft-
ware with off the shelf Linear Technology PSM demonstra-
tion boards. For a complete list of compatible demo boards,

Linduino PSM software is a set of libraries meant to facilitate
learning and software development for PMBus devices. The
portability and flexibility of the Linduino platform makes
it ideal for demonstrating a wide variety of applications.
Linduino is an Arduino compatible board with an isolated
2
I C interface and a ribbon connector that supports com-
munication with many LTC
The DC2294A Linduino Shield extends this capability to
the PSM demonstration circuits. For more information
