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.

Open Source Hardware ESP32-POE-ISO is now in stock and we are very proud with the result

ESP32-POE-ISO-2

We are very proud of our new ESP32-POE-ISO and delighted to announce it’s already in stock ready for order!

What we did with this improved version of the low cost ESP32-POE power over ethernet solution for IoT?

  1. As many requested we add 3000VDC galvanic insulation. Now you can program / debug while connected to PoE switch or router;
  2. Many asked for more GPIOs so we set SD-card in 1 bit mode and this way released 3 GPIO pins for other use;
  3. We got hints that new Espressif SDK allow ultra deep sleep modes for ESP32 and we re-designed the power supply part that now the ESP32-POE-ISO has consumption down to 200 uA (130uA of which are taken from ESP32-WROOM-32D module). The rest board without the module consumes just 70uA;
  4. As per your request now battery level has option to be monitored with the ESP32 ADC;
  5. There is External power detection option, so your software will be aware when run sole on battery and when have plenty of power.
  6. The Isolated DCDC we use is 2W and provides 400mA @5V, 100mA are reserved for the battery charge (available if no battery is connected) and 100mA are provided for ESP32, which leaves up to 200mA @5V for your additional circuit.

We love to listen to our customers and we did our the best to complete most of the requests we got with this new version.

ESP-EYE Espressif AI face detection camera supporting their AI framework is in stock

ESP-EYE

There is lot of noise around Espressif new development board with 2Mpix camera which allow to develop with their ESP-WHO AI framework. ESP-EYE was announced in january and we were waiting to be released.

Now the waiting is over! We got limited quantity from their first production run and ESP-EYE is in stock.

If you want to be among the first to play with Espressif framework for Machine Learning and AI hurry up as the quantity is limited and will not last long.

NES emulator on ESP32-POE + MOD-LCD2.8RTP

 

esp32-nes

ESP32 NES emulator allows you to run your old games on ESP32. We modified it to work with MOD-LCD2.8RTP which has touch panel so you can use it as NES controller:

touch-buttons

The modifications are included in SOFTWARE section of ESP32-POE but the example will work with any of our other ESP32 boards which has UEXT, like ESP32-EVB and upcoming ESP32-POE-ISO.

Here is video for ESP32 NESEMU in action:

Next step is to add UEXTx5 and connect MOD-Wii-UEXT-NUNCHUCK as controller.

Open Source Hardware ESP32-POE board now has new version with 3000VDC galvanic insulation

ESP32-POE-ISO

ESP32-POE is one of our best selling boards, it’s low cost less than EUR 18 in single quantity and allow you to make IoT sensor network with existing Ethernet POE infrastructure.

The end node can provide up to 4W combined on +5V and +3.3V output to external components and circuits which is more than enough for most applications.

To simplify the design and lower the cost ESP32-POE has no galvanic insulation.

Some customers asked can we add such insulation – sure it’s possible, meet the new ESP32-POE-ISO. So here above on the picture you see first samples of the insulated POE board.

We wanted to keep is as similar to existing POE as possible, as you can see the new board is just 15 mm longer and keep same pinout on the connectors, allowing ESP32-POE to be directly replaced with ESP32-POE-ISO.

What are the benefits? Now you can safely debug your ESP32-POE-ISO while connected both to computer with USB cable and Ethernet POE cable.

For the insulation we use 2W DCDC converter with 3000VAC insulation. The available 400mA are split between ESP32 and external circuit and in most application will be sufficient.

The price of ESP32-POE-ISO is EUR 23.95 (only EUR 6 more than non-isolated ESP32-POE) in single quantity.

If 2W are not enough, we can produce same board with 3W DCDC which allow 600mA current, but the price will rise with another 3 EUR to EUR 26.95 in single quantity.

Seven new version of ESP32 modules are add to our web shop

esp32-wroom-32-01-2

We add to our web shop seven new ESP32 modules:

ESP32-WROOM-32D-4MB – this is equal to used by us ESP32-WROOM-32, it uses D0WD instead of D0WDQ6 which is with smaller size and Espressif recommend it for new designs.

ESP32-WROOM-32D-16MB  has 16MB of Flash

ESP32-WROOM-32D-4MBHT is High temperature +105C module for demanding applications.

ESP32-WROOM-32U-4MB is with U.FL connector for external antenna

ESP32-WROOM-32U-16MB has 16MB of Flash

ESP32-WROOM-32U-4MBHT is High temperature +105C module for demanding applications.

ESP32-WROVER-4MB has 4MB Flash and 8MB of PSRAM.

The high temperature modules are still not in stock as Espressif manufacture these now, but all others are in stock.
