AV680RX 5.8GHZ A/V RECEIVER KIT

Rev-B Kit

INTRODUCTION

Thanks to this handy kit, building a high performance 5.8GHz
A/V receiver has never been easier. The kit provides a
custom printed circuit board set and quality electronic
components.

NOTICE: This kit requires assembly and is NOT
recommended to beginners. It is suitable for amateur radio
hobbyists, RF technicians, and engineers. The builder must
have good quality soldering tools, an anti-static work
environment, and electronic assembly experience.
