ROHM BU21078MUV-EVK-001 Evaluation Board User's Guide

About this manual

The User's Guide describes the required hardware and software to evaluate the BU21078MUV capacitive switch controller on the BU21078MUV‑EVK‑001 board. Required items include an Arduino Uno, a PC with Arduino IDE (v1.6.7 or later), a USB cable, the Sensor Shield (Shield‑EVK‑001), and the evaluation board itself.

The guide walks through connecting the board to the Sensor Shield via the I2C socket, powering the shield at 5 V, installing the BU21078MUV library in the Arduino IDE, uploading example code, and monitoring output at a baud rate of 115200. Legal and safety notices are provided at the end of the document.
