Chapter1 M200C Introduction

1. M200C Introduction

Picture1

M200C is one IOT module developed by Winext. It is small and powerful. With Winext
cloud platform and APP, we can make home appliance access to internet and we can
control the appliance by APP in smart phones.

 Cost effective

MCU is 80MHZ，and ROM is 1MB. It can support AP hotspot and STA client mode.
It supports 802.11.b/g/n，and can match most of the routers in the market.
However, the price is very competitive.

 Easy to use

M200C integrate cloud server connection, near-field control, Smartconfig
configuration，RSA handshake authentication, AES data encryption, portl data
passthrough. The clients can use M200C as a normal port, and product
development can be shortened and the product will come online quickly.

 Stable

M200Ccan support WIfi connection 24 hours a day. The firmware is stable and can
make sure the data transfer stably.

 Safe

M200C uses RSA handshake authentication and AES data encryption. This security
Mechanism protect the data transmission.
