ACT8870EVK1-102 Evaluation Tool User Guide

This document describes the characteristic and operation of the Active Semi ACT8870EVK1-102 evaluation kit (EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data.
This EVK demonstrates the ACT8870QJ102 ActivePMU™ power management IC.

Other ACT8870QJxxx options can be evaluated on this EVK by replacing the IC and any other necessary components.

To communicate with the EVK a USB Dongle and a Graphical User Interface (GUI) is provided. Download the GUI and all documentation and drivers here or in the Software TAB.

ACT8870EVK1-101 GUI

The Graphical User Interface (GUI) is packaged in a ZIP file that includes the software and all necessary drivers to communicate with the ACT8870EVK1-101 Evaluation Tool, as well as all descriptions how to use the tool.
