INTRODUCTION

Welcome to your ZFA-SK1 Dev Kit! This brief guide provides an overview of the hardware as well as safety precautions you must

observe when working with this device.

ZFA-SK1 is Always On.

There is no On / Off switch. The battery circuit will cause ZFA-SK1 to shut down when the battery has drained and there is no

external power from a USB connection. The rechargeable battery has a protection circuit which will disconnect the battery when it’s

out of energy. ZFA-SK1 can be brought back to life and will power up when you plug in a USB charger using a Micro-USB cable. Be

gentle when plugging in a charging cable. The connector is fragile and will break off if too much bending, torqueing force is applied.

SAFETY AND PRECAUTIONS

The device does not use anything higher than 5 Volts. When not charging, the maximum voltage is 4.2 Volts from the battery, and

the device operates at 1.8 Volts.
