This board which operates at 433 MHz frequency range is a remote control relay board that can be used in various electronic and robotic boards, systems which requires remote control and again systems which can be operated remotely.
4-CH RF remote control is used to turn ON / OFF four different devices independently. Any of the four outputs can be configured to work independently in either toggle or momentary mode.
This relay is based on ESP-01S WIFI module. It is designed for smart home, Internet of thing and other DIY project. With this smart relay, you will easy to DIY your smart switch to control any device by your phone anywhere. *Note: ESP8266 wifi module is not included
The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to your WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor.
This low cost yet powerful GPS receiver is based on the famous and high end u-Blox Neo-6M GPS module. It comes with small battery for hot-start, and there is built-in EEPROM too.
SIM900A Modem is built with Dual Band GSM/GPRS based SIM900A modem from SIMCOM. It works on frequencies 900/ 1800 MHz. SIM900A can search these two bands automatically. The frequency bands can also be set by AT Commands. The baud rate is configurable from 1200-115200 through AT command.
