ESP8266 Community Forum

You may have heard of the A6, the Gsm/Gprs module made by Ai-Thinker, they also made the A6C, it's the A6 with a 0.3M camera, and the A7 which is A6+GPS. Now i discovered in a chinese doc the new incoming A20 which combine A6+Camera+Esp8266(the Esp8285)!
For the price i think it will be around 15$ even less, because the A6C cost 12$ atm.
I think it will be the cheapest ready-to-use esp8285 camera, and if we can control the gsm/gprs module with the esp8266 it will be really nice.

You can have more info here about the A20: https://raymondtunning.wordpress.com/20 ... m-product/

Also for the A6C here: https://raymondtunning.wordpress.com/20 ... ution-a6c/

Hi,

Some news about the A20:
I found the A20Plus it's close to a NodeMcu with a camera. I think there is an USB to UART chip, surly the CP2102. We can also see 2 ADC pin, but the Esp8285 has only 1 no ? Weird.


They build an android application for take pictures, i think it works only with the wifi atm(we can send picture with the Gprs but surly not with this application).

The A20Plus was sold(yes idk why they stopped) to the same price as the A6C on Taobao so for AliExpress it's around 12,13$ with the camera and antennas

I found more picture and documentation, all the links are here:

Enjoy!

Hi, with A20 how do i use the Arduino IDE? Is there a board available? Or can we use any other board?

This is how you flash A20 and get it into network!

I have a single A20 Chip as well as a A20 board as shown. Both from AliExpress. I was able to flash it and to establish GSM/GPRS connection, doing http uploads and also controlling the gpios using MQTT.

I program it with Arduino IDE, just like any other ESP8266 like the famous Wemos boards.

The following link will be the last link you need to read until someone finally explains step-by-step what to do to get it running.

DIP switches for the board are explained as well as flashing procedure (this point might be the hardest for those -like me- who have only used Arduino and Wemos boards before)
Here you'll find my summary:
