WiFi + GPRS combo? Yes! ESP-12S A9 GSM GPRS IOT Node, a 2-in-1 cellular phone module with WiFi module that allows you to add location tracking, text, SMS and data to your projects. This IoT node has both WiFi and GPRS support. That means it`s perfect for any wireless or internet-connected project.
This is ESP-12S A9 GSM GPRS IOT node which is based on ESP-12S and cellular phone module A9. Both modules are all from Ai-thinker. With built-in USB and battery charging functions, it is a true IOT development board. This is very useful in your IoT projects.
The heart of the IoT node is the ESP8266 WiFi microcontroller with a clock frequency of 80 MHz and a logic voltage of 3.3V. The microcontroller contains the Tensilica chip core along with the complete WiFi stack. You can use the for Arduino IDE to program the microcontroller to implement an easy-to-run IoT core.
We hooked up a CH340C USB serial chip that can upload code at an astonishing 921600 baud rate to speed up development. It also has an auto-reset function, so there are no pin and reset button presses.
A9 is widely used in home automation, industrial wireless control, wireless location-aware devices and other Internet of Things.
SIM card! A 2G Nano SIM is required to do anything on a cellular network. AT&T in the US is no longer selling 2G SIMs and will be shutting down its 2G network, so for US customers we recommend using any T-Mobile or reseller on T-Mobile`s network (TING, SIMPLE mobile, etc.).
