ESP32-POE

You asked for it and we made it – this is one of our first prototypes of ESP32-POE board

  • ESP32-WROOM-32 module
  • UEXT connector
  • CH340 for programming
  • Si3402 PoE power managment
  • 100Mb Ethernet
  • Size 73 x 28 mm
  • two GPIOs stripes spaced at 1″ on 0.1″ step
  • Lipo battery charger
  • USB programming/power supply connector
  • micro SD card connector

ESP32-POEa

These will be available for sale end of August.

First prototypes of ESP32-EVB-EA are ready, this is new version of our popular ESP32-EVB with external antenna

ESP32-EVB-EA

ESP32-EVB is our popular board, which allow things to be connected to Ethernet or WiFi/BLE. Many customers use them in their products and always asked how to put ESP32-EVB in metal boxes, so far the internal antenna made this hard to achieve.

Now we made new version with ESP32-WROOM-32u and External antenna. First prototypes are ready and we now do testings. New metal box similar to BOX-LIME is designing now:

Our goal is to have ESP32-EVB-EA with metal box enclosure by the end of August for sale.

ESP32-PRO IoT OSHW board with 4MB RAM, 4MB Flash, co-processor with USB-OTG 256KB Flash 64KB RAM is released

ESP32-PRO.jpg

ESP32-PRO development started long time ago but with so many projects running in parallel it was always on the bottom of the priority list which was not quite fair for this board as it has excellent features:

32Mbit (4MB) PSRAM which maps on ESP32 memory space and can be used for your project.

32Mbit (4MB) fast QSPI Flash for program memory mapped to ESP32 program space.

Additional PIC32MX270F256DT processor with USB-OTG 256KB Flash and 64KB RAM which can be used as program or as USB profile like USB keyboard, serial, MIDI etc you name it.

ESP32-PROa

LiPo battery charger and management IC.

Optional Crypto engine for IoT applications.

We made two demo projects with this board which create WiFi to serial bridge you can pair two such boards and use them as wireless UART or Wireless USB Serial bridge, but the possibilities are many as the USB-OTG allow you to connect Web cameras, Flash drives and many other USB devices.

New Open Source Hardware Color TFT LCD Display 320*240 pixels with Touch panel module for direct connection to ESP32-EVB via UEXT

MOD-LCD2.8″RTP is Color TFT LCD 320*240 pixel resolution with touch panel and connects directly to ESP32-EVB via UEXT connector with cable.

Now you can add fancy UI to your IoT projects!

The documentation is on Espressif web site.

We got limited quantity from the very first manufactured lot.

New Board from Espressif – ESP32-LyraT in stock

ESP32_LyraT3

ESP32-LyraT is low cost IoT speech recognition board. It can work with many audio sources and have provisions to connect speakers, camera and LCD display.

The board documentation is skinny as this board is very new and we got limited quantity of one of the very first produced boards.

 

MOD-BME280 precise Humidity, Temperature and Pressure sensor Open Source Hardware module with UEXT and Breadboard connector

MOD-BME-u

BME280 is digital humidity, temperature and pressure sensor with I2C and SPI interface.

You can see on this link comparison of different Humidity sensors

The operating conditions are:

  • Temperature -40..+85C;
  • Humidity 0…100 % Rh;
  • Pressure 300…1100 hPa  (+9000m..-500m above sea level);

The sensor works on 3.3V and is with very low power consumption 0,1..3,6 uA.

The easiest way to connect MOD-BME280 is with UEXT connector to any board with UEXT connector as shown on the picture above.

For boards which has no UEXT connector MOD-BME280 can be connected via four jumper wires on breadboard:

MOD-BME280-b

The KiCad files are uploaded on GitHub.

The demo software use Adafruit BME280 libraries with two small modifications. The default address in MOD-BME280 is 0x76 while Adafruit library is set to 0x77.

UEXT connector requires D8 to be set LOW to power and 10 ms delay to settle the power before addressing the sensor. The code is at GitHub.

When you run it you will see this:

The sensor is very precise, if you move board up and down you can see altitude changes. The 171 meter is the altitude of Olimex building.

MOD-BME280 is perfect for IoT application for environmental conditions logging due to the low power consumption and precise measurements. It can be used both for indoor and outdoor applications.
