ESP32-POE-ISO is OSHW certified Open Source Hardware with UID BG000021
ESP32-PoE is an IoT WIFI/BLE/Ethernet development board with Power-Over-Ethernet feature. The PoE is handled by Si3402-B chip that is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. The PoE chip requires at least 37V DC to operate successfully. The board takes power from the Ethernet cable and can be expanded with sensors and actuators. Perfect solution for Internet-of-Things projects.
ESP32-POE-ISO has 3000VDC galvanic insulation from Ethernet power.
ESP32-POE-ISO-EA has module with U.FL connector and external antenna attached, which allow mounting in metal box.
ESP32-POE-ISO and ESP32-POE-ISO-EA are with commercial temperature range 0-70C
ESP32-POE-ISO-IND and ESP32-POE-ISO-EA-IND are functionally identical, but has all components qualified to work in industrial temperature grade -40+85C
ESP32-WROOM-32 - WiFi and bluetooth module (ESP32-WROOM-32UE in antenna variants)
High reliable industrial grade -40+85C available (-IND)
CE-RED and LVD certification
Original design by OLIMEX Ltd
Low power design - 200uA consumption in deep sleep
Ethernet 100Mb interface with IEEE 802.3 PoE support
3000VDC galvanic insulation between the PoE Ethernet part and board's power supply circuit
ESP32-PoE-ISO doesn't work well with bauds over 115200. What to do?
Some older drivers might have wrong timings, causing worse throughput. Download and install the latest drivers for CH340. If you are using Linux make sure to try with these drivers: high-speed driver for Linux
Is it safe to have USB powering and PoE powering connected and enabled at the same time?
Yes, when using ESP32-POE-ISO it is safe to have them both enabled.
I provide 24V to the input of ESP32-PoE-ISO's Ethernet but it doesn't seem powered. What is the problem?
Si3402 would NOT work with 24V DC. The recommended voltage is 48V DC and the minimum is around 37V DC. For more info refer to Si3402-B's datasheet.
I power the board from the Ethernet connector. What current do I have avialbe for additional circuits?
The isolated DCDC that we use provides up to 2W, this means 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.
I power the board from the battery connector. The LEDs remain off. Is it borken?
Probably not. This is a low-power design. The LEDs would not turn on when operating on battery to save power. You need other ways to determine if it works or not. For example, something over the serial lines or over the Ethernet (with no PoE enabled else it would get powered from there).
