Package includes: 1 piece of module

The product will be upgraded constantly, the appearance and color may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance.

5 Reasons to Choose SR-201 Series IoT Modules:

1. Industrial-grade STC microcontroller + ENC28J60 + stable version firmware, supports 6 network connections in TCP server mode, and also provides UDP control mode and cloud remote control function

2. The control instruction is very simple. Send 11 to open the first relay in string mode, send 21 to close the first relay, 11 * to instruct the first relay to jog, and 11K to simulate the first local key (only for local keys) Model), at 11:10 the first channel is opened for 10 seconds and automatically closed (delayed support is 1-65535 seconds); sending 00 returns all channel statuses

3. Full support for secondary development, local connection, cloud remote control, PC and mobile phone have demonstration programs with source code, and launch DLL package of module configuration program and timing program to facilitate the integration of various configuration functions

4. The hardware can be expanded. The pin on the module can be connected to real clock, 485, Bluetooth, 2.4G ...

5, 8-bit reduced instruction system is powerful

P CB size: length 70mm x width 50mm

It fully supports secondary development and exposes TCP and UDP control protocols. The cloud remote control secondary development kit provides SOAP Web Service API interface and RESTful Web Service API interface.
