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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent esp32 module *by S***N on 16 March 2022* Works well with arduino iot platform. Blynk does not support this board. ### ⭐⭐⭐⭐⭐ All in one *by E***A on 14 May 2022* Working 100% ### ⭐⭐⭐⭐ works as expected (prett much) *by H***K on 3 November 2025* Esp32 works as expected however i wasn't able to work the touch sensor work as i had seen some online where touching the GPIO pins changes the capacitance and registers an output (i hope I'm making sense). I believe it's nothing major (probably my lack of skills with these microcontrollers) as I've made other stuff work with it. ## 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.in/products/255301933-esp-wroom-32-esp32-esp-32s-development-board-2-4ghz](https://www.desertcart.in/products/255301933-esp-wroom-32-esp32-esp-32s-development-board-2-4ghz) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-07-10*
