Designed for Arduino IDE compatibility and equipped with CP2102 driver support, this durable board is perfect for professional developers seeking efficient, portable, and versatile IoT solutions. ## Description The board is not recognized? Please driver it first, or replace the USB cable Features: High performance-price ratio Small volume, easily embeded to other products Strong function with support LWIP protocol, Freertos Supporting three modes: AP, STA, and AP+STA Supporting Lua program, easily to develop Review: All 3 MCU's showed up in excelent condition. After installing the silicon labs update, all 3 MCU's were detectable on my PC. After selecting the ESP32 Dev Module and the proper com port in the Arduino IDE, all 3 MCU's were able to have sketches uploaded to them. Mine did not require the boot button to be pressed during uploading. I have tested both WiFi and BLE, both work without any issues. With the proper libraries OAT updates work reliably. The only cons to these boards is that they are not very (standard) bread board friendly, due to their width. It would be nice if the board could be narrowed up by one pin, so both side of the board can be accessed. Custom bread board can be used to access both sides. But, usually i side of the board is sufficient. More memory and usb-c would be great too. The cons are very small issues. These boards are an excelent value and I give these MCU's 5 stars. I would definatly buy these again. Review: So far, I have no complains. It is a solid construction, well packed, run as well as other ESP32 I use and the code is no problem. Happy with it! ## Features - 1. The complete solution takes up the least printed circuit board area. This board is used with 2.4GHz dual-mode WiFi and wireless chips using 40nm TSMC low-power technology. - 2. The best power and RF characteristics are safe, reliable and scalable for various applications. - 3. Meticulous workmanship: The meticulous design, perfect in workmanship, durable and long service life. - 4. Compact and portable: being so mini and light-weight, this product does not take much space and can be easily taken away. - 5.For Arduino IDE,choose ESP32 DEV,make sure that your program or run a program smaller than the ESP32 configuration - 6.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. - 7.you need to driver the CP2102 before you can start using it - 8. Durable material: This product is made of high-quality material, durable, long service time, firm and stable in use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08246MCL5 | | Batteries Included | No | | Batteries Required | No | | Brand | Teyleten Robot | | Compatible Devices | Smartphones, Laptops, Tablets | | Connector Type | Bluetooth, Wi-Fi | | Customer Reviews | 4.5 4.5 out of 5 stars (593) | | Date First Available | 13 December 2019 | | Hardware Interface | USB | | Item Dimensions LxWxH | 5.1 x 2.8 x 1.2 Centimeters | | Item Weight | 30 g | | Item model number | A9 | | Manufacturer | Teyleten Robot | | Memory Storage Capacity | 512 KB | | Model | A9 | | Model Name | ESP32 | | Mounting Hardware | CP2102, Reset button, Boot button | | Number of items | 3 | | Operating System | FreeRTOS | | Processor Brand | Espressif | | Processor Count | 2 | | Processor Speed | 2.4 GHz | | Processor Type | Core M Family | | Product Dimensions | 5.15 x 2.85 x 1.23 cm; 30 g | | Ram Memory Installed Size | 0.51 MB | | Ram Memory Technology | [POSSIBLE: LPDDR2, DDR2] | | Total USB ports | 2 | | Wireless Type | Bluetooth | ## Product Details - **Brand:** Teyleten Robot - **CPU Model:** Core M Family - **Memory Storage Capacity:** 512 KB - **Model Name:** ESP32 - **RAM Memory Installed Size:** 0.51 MB ## Images ![Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - Image 1](https://m.media-amazon.com/images/I/41+7NdzO0JL.jpg) ![Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - Image 2](https://m.media-amazon.com/images/I/419WMp4e9WL.jpg) ![Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - Image 3](https://m.media-amazon.com/images/I/41MA-+RvSnL.jpg) ![Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - Image 4](https://m.media-amazon.com/images/I/41NKSZG5LlL.jpg) ![Teyleten Robot ESP32S ESP32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 3PCS) - Image 5](https://m.media-amazon.com/images/I/41TNqe9uEhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***. on 22 June 2025* All 3 MCU's showed up in excelent condition.

Happy with it! ### ⭐⭐⭐⭐ Review *by D***G on 24 December 2025* I am giving this one star to increase visibility for other new users. Your chip is unlikely defective. As a beginner I was trying to use it in the Arduino IDE via the Dronebotworkshop tutorials. Here's what I learned from there, here, and reddit. I got my chips to work. *** If you are having trouble connecting and getting errors like COM3 device error message 2 or whatever there is one more thing you have to do. But I will go through the steps in order until we get there. 1. Open the arduino IDE 2. Go to File | Preferences. Under the Settings tab look at the "Additional boards manager URLs:" There is a blank text box there. If there is already a link there, place a comma then a space after it and add the following link: Amazon asked me to remove link. Its at github and called: "package_esp32_index.json" click on "OK" 3. Go to Tools | Board Manager and navigate to "ESP32 Dev Module" and select that. You can try to run the program at that point while holding down the boot button on the esp32. That may be enough for you but not for me. 4. After some back and forth to Reddit and here I saw that on the amazon product description it says to "install the CP2102 driver or the chip won't work." They were right. lol. Mine did not. 5. Navigate to the silicon labs website and download the driver's zip folder at the following URL: Amazon asked for me to remove link. Its at Silicon Labs website I am running windows so I chose the "CP210x Universal Windows Driver v11.4.0". In my "downloads" folder I found the zip file and extracted it to a newly created folder in my "c:\Program Files\ESP32 Driver Stuff". I named it so I could find it, if disaster struck. Spoiler... it did not. I then went to "Device Manager" in the control panel of windows. I found the CP2102 UART to USB entry under the COM/LPT entry. I right clicked and updated the drivers by "Browsing" and selecting the c:\Program Files\ESP32 Driver Stuff folder that I created above. Dang. still didn't work. BUT I noticed it was now on COM6. So I went back to the Arduino IDE and Tools | Port | to COM6. "Holy Sh*t! Hallelujah! Where's the Tylenol?" - Clarke W. Griswold It worked. I hoped this helped. ## Frequently Bought Together - Teyleten Robot ESP32S ESP32 ESP-WROOM-32 Development Board 2.4GHz Dual-Core WiFi +Bluetooth 2 Function Microcontroller for Arduino (ESP32 30P, 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 - BOJACK 3 Values 130 Pcs Solderless Breadboard 4 Pcs 830 Tie Points & 400 Tie Points & 126 Pcs Flexible Breadboard Jumper Wires --- ## 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.pt/products/377797337-teyleten-robot-esp32s-esp32-development-board-2-4ghz-dual-core](https://www.desertcart.pt/products/377797337-teyleten-robot-esp32s-esp32-development-board-2-4ghz-dual-core) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-24*
