Review: Works great...but needed an external capacitor to initiate a power-on-reset - Needed a 10uF capacitor between GND and IO0 to reliably reset after a power cycle. Works reliably after that. Ethernet performance/speed is great. ## Features - ESP32 series ICs are SOCs that integrate 2.4GHz Wi-Fi and Bluetooth dual-mode, with ultra-high stability, versatility, reliability, and ultra-low power consumption. - Adopts dual-core Xtensa@ 32-bit LX6 MCU. Integrated SPI Flash 32Mbitl/SRAM 52OKB supports TCP Server, TCP Client, UDP Server, UDP ClientT mode. - Supports serial port, wifi, Ethernet, and Bluetooth data ports in pairs. Transparent data transmission Supports firmware upgrade by connecting to the network over a wired network or wifi. - Supports wifi to connect to the Internet or LAN through a router, establish a TCP/UDP connection, access the user's designated server, support wired network access, and support user secondary development. - Five functions:①Socket function (Socket working mode is divided into four types: TCP Client, TCP Server,UDP Client, and UDP Server, which can be set by AT commands)②Serial port function③Bluetooth function④Wifi function⑤Wired network port access function(Development board is connected to the Internet or local area network through a wired network,Socket function can be configured through AT commands, a TCP/UDP connection can be established, and the user's designated server can be accessed) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Z298QJQ | | Box Contents | USB cable | | Brand | EC Buying | | Brand Name | EC Buying | | CPU speed | 2.4 GHz | | Compatible Devices | devices with Wi-Fi, Bluetooth, serial port, or Ethernet capability | | Connectivity technology | Wi-Fi | | Customer Reviews | 4.4 out of 5 stars 50 Reviews | | Item Dimensions L x W x H | 5.5L x 2.6W x 1.7H centimetres | | Item Weight | 15 Grams | | Manufacturer | EC Buying | | Manufacturer Part Number | WT32 | | Memory Storage Capacity | 4 MB | | Memory storage capacity | 4 MB | | Model Name | WT32-ETH01 | | Model Number | WT32-ETH01 | | Model name | WT32-ETH01 | | Network Connectivity Technology | Wi-Fi | | Operating System | FreeRTOS | | Processor Brand | Espressif | | Processor Count | 2 | | Processor Speed | 2.4 GHz | | RAM Memory Installed | 4 MB | | RAM Memory Technology | DDR | | RAM memory installed size | 4 MB | | Total USB Ports | 1 | | Wireless Compability | 802.11b/g, Bluetooth | ## Product Details - **Brand:** EC Buying - **Model Name:** WT32-ETH01 - **Ram Memory Installed Size:** 4 MB - **Memory Storage Capacity:** 4 MB - **CPU Speed:** 240 Hz ## Images ![WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - Image 1](https://m.media-amazon.com/images/I/617s-2l1dwL.jpg) ![WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - Image 2](https://m.media-amazon.com/images/I/71Fxt7LgusL.jpg) ![WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - Image 3](https://m.media-amazon.com/images/I/712ENe0NLSL.jpg) ![WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - Image 4](https://m.media-amazon.com/images/I/71XKk71FhAL.jpg) ![WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - Image 5](https://m.media-amazon.com/images/I/71o0+HrbxzL.jpg) ## Questions & Answers **Q: there is any model can be powered by PoE?** A: The wESP32 can. It is here on Amazon as well. **Q: can it be powered by ethernet poe?** A: No, it can't be powered by ethernet poe. **Q: does this support poe** A: No, the WT32-ETH01development board doesn't support POE, power supply by header pin. **Q: Does this work with the arduino ide via the serial?** A: Yes, but you need to develop your own research, we only provide IDF data cases ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for home automations *by J***R on 14 April 2025* Perfect for home automations and can fit in small spaces pretty inconspicuously. ### ⭐⭐⭐⭐⭐ Works great...but needed an external capacitor to initiate a power-on-reset *by K***S on 29 December 2024* Needed a 10uF capacitor between GND and IO0 to reliably reset after a power cycle. Works reliably after that. Ethernet performance/speed is great. ### ⭐⭐⭐⭐⭐ great combination of features, low price *by K***H on 12 January 2023* I needed a controller board with both WiFi and an Ethernet port. There's no documentation that comes with the board, but there's plenty of youtube videos and posts about it online. I was able to get it connected and working in a few minutes. You'll need a USB to TTL converter to program the board. I used the HiLetgo CP2102 USB 2.0 to TTL Module Serial Converter Adapter Module USB to TTL Downloader with Jumper Wires. That device also provides 5V for the board. There is Arduino development environment support for this module. You'll find some how to instructions if you search for the board name and Arduino. The pins are soldered "upside down" from the typical orientation, but that doesn't matter for my project. If you search for wireless tag WT32-S1 you'll find useful documentation about the chip, pin outs, etc.. ## Frequently Bought Together - EC Buying WT32-ETH01 Development Board, ESP32 Development Board Module Embedded Serial Port to Ethernet 2.4GHz Wi-Fi & Bluetooth Dual-Mode Support WiFi, Ethernet, Bluetooth Output Ethernet Converter - HiLetgo CP2102 USB 2.0 to TTL Module Serial Converter Adapter Module USB to TTL Downloader with Jumper Wires - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/700883296-wt32-eth01-development-board-esp32-development-board-module-embedded-serial](https://www.desertcart.jp/products/700883296-wt32-eth01-development-board-esp32-development-board-module-embedded-serial) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-06-16*
