Sub-G wireless module solution

Published time : 2018-04-18 wireless interconnection
The Sub-G wireless module solution mainly uses the HC16LC series MCU of Huada Semiconductor.To improve the wireless interconnection field and enable users to fully enjoy the fun of wireless Internet access.

Solution Introduction

The wireless module is a high-performance IoT wireless transceiver that can be widely used in short-range IoT wireless communication in various applications.

The utility model has the advantages of small volume, low power consumption, long transmission distance, strong anti-interference ability and low cost.

The module is compact in design and small in size. The module has an MCU with integrated RF module. The interface is completely open to the outside world. When the customer uses it, it avoids the difficulty of RF hardware design and has more flexible secondary development space in software and product structure. .

The Huada MCU HC16LC series uses the C80251 core, which has 40 times the processing power of the standard C8051 at the same time and frequency.
