A.I. Thinker, a company known for its ESP8266 module, has designed a new intriguing product with A20Plus board powered by Espressif ESP8266 (or ESP8285) WiFi SoC, that also features GPRS connectivity, and a 0.3MP camera.
There’s basically no info on the “English Internet”, but Raymond Tunning found lots of info in Chinese, and posted information and links on his blog.
A20 Plus board specifications:
- Wireless Module – A.I. Thinker A20 module with GPRS and WiFi (ESP8266 or ESP8285), two antennas connector
- Camera – VGA camera interface (up to 640×480 resolution) compatible with OV7670, GC0308, GC0328, & GC0309 sensors.
- Expansion – 2x headers with GPIO, ADC, power signals…
- USB – 1x micro USB port for power and programming
- Misc – Reset and user button, two LEDs (for flash?)
- Dimensions – TBC
An Android app (binary + source code) is provide to retrieve pictures (apparently no video for now) over WiFi or GPRS.
Some other documentation in Chinese to use and program the app in Android Studio can also been found here (password: 123456), and more info about the module is available on A.I Thinker forums, where we’ll also find they have a few other modules to offer.
A6 module only support GSM/GPRS, A6C module supports GPRS and camera (but no WiFi), and A7 module supports GPRS and GPS. Hopefully, they’ll have a 3G module soon enough, since I’m not sure GPRS is available everywhere anymore.
A20 Plus board is listed on Taobao for $49RMB (~$7.4), but shown as out of stock for now.
