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:
