ESP32-ADF is a ESP32 development board created for Espressif Audio Framework. It has an audio amplifier, stereo microphones and a build-in programmer.

We created an internet radio project and uploaded on GitHub.

To complete the project you need:

Here is the radio in action:

Unfortunately, it has weak bass sound since the speakers are not mounted in a box.

 

ESP32 new boards in stock

ESP32-PICO-KITb

Espressif never stop to surprise us with new products. Their new ESP32-PICO-D4 IC has build in 4MB SPI Flash and quartz crystal, antenna matching circuit, so this chip requires just 5 external resistors and capacitors to work! If your design has to be small this is the chip for you!

ESP32-PICO-KIT is low cost development board for this new chip and has build in USB serial programmer, antenna and breadboard friendly DIL header connectors at 0.1″ step.

ESP32-CAM-F

ESP32-CAM is WiFi IP camera with OV2640 2 Mpix sensor it works with internal PCB antenna and needs just 3.3V external power supply to  operate. You also have SD-card connector and GPIOs to which you can connect PIR sensors and other components to control.

There is Arduino support for this board and tons of interesting projects like face recognition, motion detectors with storage of the pictures on the SD card and etc.

Here are few of them:

We also got ESP32-CAM-UFL which is same board but with U.FL connector where you can connect external antennas.

ESP32-CAM-ANT1

ESP32-CAM-EA is ESP32-CAM with small external WiFi/BT antenna which increased the WiFi coverage.

ESP32-CAM-ANT2

If you need more coverage we have ESP32-CAM-EAX which has higher gain antenna, but with quite bigger size.

ESP32-ADF based SIP Phone looks really cool with LittlevGL

esp32-adf-sip1

We blogged a while ago about one of the demo code we work on for ESP32-ADF – SIP IP phone. Our vacation delay a bit this project, but now it’s almost ready and we want to share some details.

We used LittlevGL framework for the UI. You can see on the picture above how the phone app looks on the LCD.

LittlevGL required some touching as default didn’t work well with the touch screen, but we managed to add support, the touch panel recognize gestures like slide, tap etc.

We need few more days to finish dialing sounds etc details and will upload on GitHub our patches for LittlevGL and our SIP IP phone demo.

We are so impressed with the result that we may release soon all in one LCD+ESP32-ADF and camera so we enhance the phone with camera and open more applications like Home automation WiFi Door-Phone, security panel with sound and video and other apps based on this configuration.

ESP32-ADF Internet Radio example now uses LoBo with 2.8″ TFT LCD and touch screen

 

The Internet Radio demo for ESP32-ADF now includes MOD-LCD2.8RTP and LoBo for UI. Updated version is uploaded on GitHub.

Google assistant, Google DialogFlow, Amazon Alexa and internet radio demo code for ESP32-ADF are uploaded on GitHub

ESP32-ADF1

Some demo codes for ESP32-ADF are now uploaded on the GitHub.

Google Assistant demo will allow you to build your very own Google Assistant speaker, display and to integrate these services in your future product.

Internet Radio is preliminary and we still work on the UI to be uploaded later this week.

Amazon Alexa is the GA competitor and you can embed it with your Home assistant and automate your home.

Google Dialogflow is easy way to use Google AI in your products and make them voice controllable. It builds voice to text service and you will receive plain text delivered from the voice the device listen to. This way you can add voice control to every of your products. All you need is internet connection.

The SIP phone demo is also to be uploaded later this week.

First batch of ESP32-ADF is sold out, we will have new stock after our summer vacation

ESP32-ADF

Our first batch of ESP32-ADF is sold out now we work on second batch but will have no time to complete before our Summer vacation, so new stock will be available after August 18th.

For these who didn’t managed to get one there is notification link on the product page which will notify you when the board is back in stock.

 

ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO boards now have option with external antenna and all our ESP32 boards can be build in extended temperature range -40+105C for demanding applications

ESP32-POE-ISO

Our popular ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO now has option with external antenna, so you can use them even with metal boxes. The external antenna extends their range by 20-30%.

We stock now ESP32 modules with 16MB of Flash, so if you run out of memory you can order any of our ESP32 boards with 16MB Flash module too.

Also we have ESP32 modules in extended temperature range -HT (high temperature) which works from -40C up to 105C for demanding applications.
