Opening it shows a confirmation page with live pricing and stock before anything is added to the cart. - **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/TPH-106365:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.) - **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there. - **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works) - **Payment methods, purchase orders, policies and contact details:** https://core-electronics.com.au/llms.txt ## Description The Olimex **ESP32-POE-ISO-EA** is an ESP32-powered WiFi/BLE/Ethernet development board with an **external antenna**, **Power-Over-Ethernet**, **galvanic isolation** and **LiPo charging**. ESP32-POE-ISO-EA has **3000VDC galvanic insulation** from the Ethernet powering. It is the perfect addition to any project that requires connectivity and is recommended hardware on the [ESPHome Ready-Made projects page](https://esphome.io/projects/?type=bluetooth) for a **Bluetooth Proxy**. The PoE is currently handled by a TPS2375PW chip that is **IEEE 802.3-compliant**, including pre-standard (legacy) PoE support. The PoE powering requires at least 37V DC to operate successfully. The board takes power from the Ethernet cable and can be expanded with sensors and more. ESP32-POE-ISO-EA has **ESP32-WROOM-32UE** module with U.FL connector and external antenna attached, which can be panel mounted. the board can operate in the commercial temperature range of 0-70C. The board supports **LiPo charging** with a JST-PH connector for your [LiPo battery](https://core-electronics.com.au/power-batteries/liion-lipoly/2-pin.html) and includes a **microSD slot**. ### Features - ESP32-WROOM-32UE module with WiFi and Bluetooth - 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 the board's power supply circuit - Micro USB connector for ESP32 programming - MicroSD card working in 1 bit mode (3 more GPIOs) - LiPo battery charger with LiPo battery connector - Battery level monitor pin on ADC - External power supply detection pin on ADC - DC-DC 2W 5V/400mA - UEXT connector - User button - Reset button - Two extension connectors, 0.1" step spaced at 1" - PCB dimensions: 98 x 28mm Resources ### Documents - [ESP32-POE-ISO user manual](https://core-electronics.com.au/attachments/localcontent/ESP32-POE-user-manual_17383db9ab4.pdf) - [ESP32-POE-ISO latest schematic in PDF format](https://core-electronics.com.au/attachments/localcontent/ESP32-PoE-ISO_Rev_L_1769845e581.pdf) - [ESP32-POE-ISO GPIO map](https://core-electronics.com.au/attachments/localcontent/ESP32-POE-ISO-GPIO_751420eafbd.png) - [ESP32-POE-ISO European Declaration of Conformity](https://core-electronics.com.au/attachments/localcontent/EU-DOC-ESP32-POE-ISO_89609394b63.pdf) - [ESP32-POE-ISO UKCA Declaration of Conformity](https://core-electronics.com.au/attachments/localcontent/UKCA-DOC-ESP32-POE-ISO_10153b76df0.pdf) ### Hardware - [ESP32-POE-ISO CAD files on GitHub](https://github.com/OLIMEX/ESP32-POE-ISO) - [Board Dimensions](https://github.com/OLIMEX/ESP32-POE-ISO/tree/master/HARDWARE/Dimensions) ### Software - [Simple Ethernet demo for ESP-IDF](https://github.com/OLIMEX/ESP32-POE/tree/master/SOFTWARE/ESP-IDF) - [Works with default Arduino for ESP32](https://github.com/espressif/arduino-esp32) (if you have troubles refer to [this document)](https://www.olimex.com/Products/IoT/ESP32/_resources/Arudino-ESP32.txt) - [Simple Ethernet and SD card demo for Arduino](https://raw.githubusercontent.com/OLIMEX/ESP32-POE/master/SOFTWARE/ARDUINO/ESP32_PoE_Ethernet_SD_Card_Arduino/ESP32_PoE_Ethernet_SD_Card_Arduino.ino) - [LCD screen demo for Arduino](https://github.com/OLIMEX/MOD-LCD2.8RTP/tree/master/SOFTWARE) - [WIFI webserver and UEXT demo for Arduino](https://raw.githubusercontent.com/OLIMEX/ESP32-POE/master/SOFTWARE/ARDUINO/ESP32_PoE_WebServer_MOD_IO/ESP32_PoE_WebServer_MOD_IO.ino) - [More Arduino examples on our GitHub pages](https://github.com/OLIMEX/ESP32-POE/tree/master/SOFTWARE/ARDUINO) ### USB Drivers - [USB driver for Windows](https://core-electronics.com.au/attachments/localcontent/CH341SER_23442da278c.zip) - [High-speed USB driver for Linux](https://github.com/OLIMEX/ch340-dkms) - [USB driver for Linux (for old kernels; pre-3.14.x)](https://core-electronics.com.au/attachments/localcontent/CH341SER_LINUX_8703502db9.ZIP) - [USB driver for Mac](https://core-electronics.com.au/attachments/localcontent/CH341SER_MAC_152059e807d.ZIP) ## Images - [Product image 1](https://core-electronics.com.au/media/catalog/product/T/P/TPH-106365-1.jpg)
