Designed for Arduino compatibility, it offers pre-soldered pins for easy prototyping, a built-in voltage regulator supporting 5V input, and supports multiple network modes (AP, STA, AP+STA). Ideal for developers seeking a powerful, versatile platform for IoT and embedded applications. ## Description This board is already soldered! Data Feature: Complete microcontroller with WLAN (802.11bgn) and Bluetooth (Classic and LE). Reset and boot buttons are available, so a new firmware can be quickly and easily installed. The development board combines a CPU with 2 Tensilica LX6 cores, clocked at up to 240 MHz, and 512 kilobytes in a single microcontroller chip. Warm Tips: When you download the program to development board, you need to press the IOO button for 1-2 seconds. 38P and 30P board sizes and circuit layouts are different. ## Features - 1. The Development Board continues 1.0 classic design, eliciting most I/O to both sides of the needle, developers can connect peripherals according to their own needs. - 2. When using breadboard for development and debugging, the standard needle arrangement on both sides can make the operation more simple and convenient. - 3.small volume. Easy to embed into any product - 4.Powerful, support LWIP protocol, freertos - 5.Support three modes: AP, STA, AP+STA coexistence mode - 6.For arduino IDE,choose ESP32 DEV,make sure that your program or run a program smaller than the ESP32 configuration - 7.The maximum operating voltage of the ESP32 is 3.3V. The ESP32 has an on-board voltage regulator that can withstand voltages up to 5V using the VIN and GND pins. Once a voltage is input to the ESP32 development board's VIN pin, that voltage is passed through the ESP32's on-board voltage regulator (AMS1117), which outputs a constant 3.3V, which is the board's operating voltage. Note: The maximum operating voltage of the ESP32 is 3.3V.The maximum voltage that can be applied to the ESP32 Development Board from the VIN pin is 5V.USB power supply is 5V. - 8.you need to driver the CP2102 before you can start using it - 9.32S is the core development board based on ESP-32S module. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09J95SMG7 | | Best Sellers Rank | #351 in Single Board Computers (Computers & Accessories) | | Brand | Teyleten Robot | | Built-In Media | [Reset and boot buttons] | | CPU Model | ARMv7 | | Compatible Devices | Arduino, Microcontrollers, Computers | | Connectivity Technology | Bluetooth, Wi-Fi | | Customer Reviews | 4.5 4.5 out of 5 stars (235) | | Item Dimensions L x W x H | 0.19"L x 0.1"W x 0.05"H | | Manufacturer | Teyleten Robot | | Memory Storage Capacity | 524288 bytes | | Model Name | ESP32 | | Number of Items | 3 | | Number of Packs | 3 | | Operating System | FreeRTOS | | Processor Brand | Espressif | | Processor Count | 2 | | Processor Speed | 0.24 GHz | | RAM Memory Installed | 524288 bytes | | RAM Memory Technology | SRAM | | Total Usb Ports | 1 | | Wireless Compability | 802.11bgn | ## Product Details - **Brand:** Teyleten Robot - **CPU Model:** ARMv7 - **Memory Storage Capacity:** 524288 bytes - **Model Name:** ESP32 - **Ram Memory Installed Size:** 524288 bytes ## Images ![ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 38P, 3PCS) - Image 1](https://m.media-amazon.com/images/I/71Cjuq-cSRL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 38P, 3PCS) - 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 - 4PCS Breadboards Kit Include 2PCS 830 Point 2PCS 400 Point Solderless Breadboards for Proto Shield Distribution Connecting Blocks --- ## 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.at/products/373112899-esp32s-esp32-development-board-2-4ghz-dual-core-wifi-bluetooth](https://www.desertcart.at/products/373112899-esp32s-esp32-development-board-2-4ghz-dual-core-wifi-bluetooth) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-07*
