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 Si3402-B chip is IEEE 802.3-compliant, including pre-standard (legacy) PoE support. 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-WROOM-32 - WiFi and bluetooth module
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
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).
