QCIOT-5APWRPOCZ
The QCIOT-5APWRPOCZ power board enables
quick prototyping of the
Quiescent Current Integrated Switching Regulator in
a custom system design. The
Digital Power Monitor is designed to measure and
control the regulator output of the RAA211651 with
margining.
The board provides a standard Pmod™ Type 6A
2
(extended I
C) connection for the on-board sensor to
plug into any required MCU evaluation kit with a
matching connector. The QCIOT-5APWRPOCZ
features Pmod connectors on both sides of the board
to allow additional Type 6/6A boards to connect in a
daisy-chained solution with multiple devices on the
same MCU Pmod connector.
The software support that is included with the
2
Renesas IDE
(e
studio) provides code generation
to connect the device and the MCU so that
development time is significantly reduced. With its
standard connector and software support, the
QCIOT-5APWRPOCZ is ideal for the Renesas
Quick-Connect IoT to rapidly create an IoT system.
