Limited Quantity of the new ESP32-S2 multimedia and breadboard development boards from Espressif are in stock!

ESP32-S2-Kaluga-1

ESP32-S2 is new SOC from Espressif which is supposed to solve some issues with current ESP32 and ESP8266 SOC chips.

First issue S2 solves is the small number of GPIOs ESP32 has, specially if you want to use the Ethernet interface. ESP32-S2 comes with 37 GPIOs in nice 5x5mm QFN28 package. The SOC is single core 240Mhz processor with build in USB interface. The Bluetooth and Ethernet interfaces are removed.

Pricewise ESP32-S2 is cheaper than ESP32 but a bit more expensive than ESP8266.

ESP32-S2-WROOVER module comes with 2MB of RAM and 4MB of Flash and will be able to replace ESP8266 everywhere while having enough resources to run secure SSL connection.

Two development boards are available for ESP32-S2.

ESP32-S2-Saiola-1R is the low cost entry breadboard experimental board which includes ESP32-S2-WROVER module, USB programmer, RGB LED and couple of buttons.

It has all GPIOs exposed for experiments:

The second board is ESP32-S2-Kaluga-1 which is multimedia board with camera, microphone, audio codec, 3.2″ LCD with touch screen, speaker:

ESP32-S2-Kaluga-1b

The kit comes with Camera module:


ESP32-S2-Kaluga-1c

and touch sensor plate:

ESP32-S2-Kaluga-1e

Kaluga multimedia board is so new that still not have page at Espressif site, so all info is in their GitHub repository.

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.

 

Are you ready to play with Do-It-Yourself Alexa Speaker, WiFi SIP phone, WiFi walkie-talkie, Internet Radio player and broadcasting? Then the Open Source hardware ESP32-ADF is the right board to start with!

ESP32-ADF

With ESP32-WROOM-B module with 8MB RAM and 4MB of Flash, two microphones, two 3W speakers, codec, amplifier, Lipo charger, USB with programming, Audio 3.5mm jack, ESP32-ADF board offers everything you need to start playing with Espressif Audio Development Framework.

Today we made our first Alexa prototype:

and we spoke with ESP32-ADF running WiFi SIP phone, you do not need PC to make free calls all around the world to other people with VoIP phones!

Surprisingly there was no any lag caused by the WiFi and it works as good as the commercial wired SIP VoIP phones.

We add now MOD-LCD2.8RTP with touch screen on ESP32-ADF UEXT connector and write some nice graphical UI then will upload the VoIP phone demo code next week.

We do same for the Internet Radio player demo – nice graphical UI, so user can select which radio station to connect to.

 

New ESP32 Development board in stock ESP32-DevKit-Lipo target handheld applications with build in LiPo charger

ESP32-DevKit-LiPo

ESP32-DevKit-Lipo is pin to pin compatible with Espressif ESP32-CoreBoard (ESP32-DevKitC) board, but adds additional LiPo charger and battery connector, allowing board to work from LiPo battery when external power supply is missing.

Tomorrow 16.10 at SofUnitConf in Paradise Center in Sofia we will have Workshop with this board to show how easily it could be programmed with JavaScript and Espruino.

ESP32-POE Open Source Hardware IoT development board with WiFi/BLE/100Mb Ethernet with 802.3 POE is in stock!

ESP32-POE-1

ESP32-POE board is now in stock. The prices start from EUR 14.36 for 50 pcs order.

This board offers Open Source Hardware / FOSS solution and building block for distributed sensor network with power over existing LAN infrastructure.

Possible use cases are Home automation, Industrial machine logging, remote environmental monitoring, access control, remote displays etc.

The board contains ESP32-WROOM-32 module with WiFi/BLE and Ethernet connectivity , RESET and USER buttons, micro SD card, LiPo battery charger and LiPo connector which allow board to work even with power supply drops.

The UEXT connector on the board can be used to connect many different sensors like:

Si3402-B chipset takes care for the power over ethernet, it’s IEEE 802.3 compliant, including pre-standard (legacy).

Important notice, to keep board compact and as it’s main purpose is to connect to cloud different remote sensors there is no galvanic isolation between board and the power delivered by the LAN switch or router.

ESP32-POE has internal programming interface and you can program it with Espressif SDK or Arduino via USB cable. As the board is not galvanic isolated from the Ethernet power supply, before you connect the USB cable to your computer you should remove the Ethernet cable or you should use USB-ISO between your computer the ESP32-POE!
