IoT Development Board with All in one WiFi Cellular GPS tracking

WiFi+Cellular + GPS tracking, all in one? Oh yes! Introducing ESP-12S A9G GSM GPRS+GPS IoT Node, an all-in-one cellular phone module with a WiFi module that lets you add location-tracking, text, SMS, and data to your project.

This IoT node has both WiFi and GPRS support. That means it’s perfect for just about any wireless or Internet-connected project.

This ESP-12S A9G GSM GPRS+GPS IoT Node is based on the ESP-12S and the cellular phone module A9G both modules all are from Ai-thinker. With built-in USB and battery charging, it is a really a great IoT development board. It will be very useful for all your IoT projects.

At the IoT Node’s heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core.

We wired up a CH340C USB-Serial chip that uploads the code at a blistering 921600 baud for fast development time.

It also has auto-reset so no noodling with pins and reset button pressings. The A9G can be used in a wide range of IoT applications and is ideal for IoT applications for home automation, industrial wireless control, wearable electronics, wireless location sensing devices, and other IoT applications.

ESP-12S Feature

  • ESP8266 @ 80MHz with 3.3V logic/power
  • 4MB of FLASH (32 MBit)
  • Built in WiFi 802.11 b/g/n
  • 3.3V regulator with 500mA peak current output
  • Auto-reset support for getting into bootload mode before firmware upload
  • 4 x GPIO pins – can also be used as I2C
  • 1 x analog inputs 3.3V max
  • Built in 500mA LiPoly charger with charging status indicator LED
  • Reset button

A9G Feature

  • Quad-band 850/900/1800/1900MHz – connect onto any global GSM network with any 2G SIM
  • Fully-integrated GPS
  • Send and receive SMS messages
  • Send and receive GPRS data (TCP/IP, HTTP, etc.)
  • Support standard GSM07.07, 07.05
  • AT commands and Ai-Thinker extended commands
  • Support GPS, BD
  • Nano-SIM Cardholder


  • SIM Card! A 2G Nano SIM card is required to do anything on the cellular network. US AT&T no longer sells 2G SIMs and will shut off their 2G network, so for American customers, we recommend any T-Mobile or reseller (TING, SIMPLE mobile, etc) that uses the T-Mobile network.
  • We added a connector for 3.7V Lithium polymer batteries and built-in battery charging. A 500mAh+ Lipoly battery is required for use, it keeps the cellular module happy during the high current spikes. Plug the IoT Node into micro USB to charge at 500mA.

  1. Hi,
    Is this IoT Development Board With All In One WiFi Cellular GPS Tracking still vailable?
    If available, I require about 200 units.
    Best Regards
