Using Node32s as the Board selection. To reference GPIO pins in code use just the number, for example "digitalWrite(13, HIGH)" sets GPIO13 high. The built-in LED to GPIO2. ## Features - 2.4GHz Dual Mode WiFi + Bluetooth Development Board - Ultra-Low power consumption, works perfectly with the Arduino IDE - Support LWIP protocol, Freertos - SupportThree Modes: AP, STA, and AP+STA - ESP32 is a safe, reliable, and scalable to a variety of applications ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0718T232Z | | Best Sellers Rank | #1,254 in Computers ( See Top 100 in Computers ) #4 in Single-Board Computers | | Brand | HiLetgo | | Built-In Media | 1 * ESP32 Development Board | | CPU Model | core_m | | Compatible Devices | Devices with Wi-Fi and Bluetooth connectivity | | Connectivity Technology | Bluetooth, Wi-Fi | | Customer Reviews | 4.4 4.4 out of 5 stars (1,566) | | Manufacturer | HiLetgo | | Mfr Part Number | 3-01-1287 | | Model Name | ESP-WROOM-32 | | Model Number | 3-01-1287 | | Number of Items | 1 | | Number of Packs | 1 | | Operating System | FreeRTOS | | Processor Brand | Espressif | | Processor Count | 2 | | Processor Speed | 2.4 GHz | | RAM Memory Technology | LPDDR2 | | Total Usb Ports | 1 | | Unit Count | 1 Count | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** HiLetgo - **CPU model:** core_m - **CPU speed:** 2.4 GHz - **Connectivity technology:** Bluetooth, Wi-Fi - **Model name:** ESP-WROOM-32 ## Images ![ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA for Arduino IDE - Image 1](https://m.media-amazon.com/images/I/61oLjkzaIIL.jpg) ## Questions & Answers **Q: is there a pin out diagram for this board ?** A: On the board I received today, October 18, 2017, there are NO pin labels on the bottom of the board. In fact, there is no labeling at all, contrary to the product pictures above. The board has no pin labels on top, either. The NodeMCU documentation I have just found has a completely different set of pin assignments as compared to the pictured pin labels above. **Q: I've downloaded every driver i can find and neither my pc nor my mac will recognize this thing. help?** A: One of the reviewers said it required CH210 instead of the usual CH340 or CP2102. Since this is an old question it may not help you, but I hope this helps someone down the road, **Q: Are these Rev0 or Rev1 of the esp32 chip?** A: The chip revision is 1. I obtained this by running the code to retrieve it from the ESP32 module itself, so I know it's accurate. My delivery date was Jul 12, 2017. **Q: set esp32 as web server, but lost connection after 1 minutes, maybe wifi sleep, is there any way not wifi sleep?** A: This ESP32 has dormant function, but only if you write a command in the software and enable it, the dormant function will be eabled. If like this, please remove this command. If you didn't write such a command, the disconnection may be due to weak wifi signal or the wifi has large interference. ## Frequently Bought Together - HiLetgo ESP-WROOM-32 ESP32 ESP-32S Development Board 2.4GHz Dual-Mode WiFi + Bluetooth Dual Cores Microcontroller Processor Integrated with Antenna RF AMP Filter AP STA for Arduino IDE - 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 - HiLetgo 3pcs TP4056 Type-c USB 5V 1A 18650 Lithium Battery Charger Module Charging Board with Dual Protection Functions --- ## 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.no/products/255301933-esp-wroom-32-esp32-esp-32s-development-board-2-4ghz](https://www.desertcart.no/products/255301933-esp-wroom-32-esp32-esp-32s-development-board-2-4ghz) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-16*
