Review: I only started using ESP32 a few months ago, coming from an Arduino background. I have to say, I love these boards! They are much faster than any Arduino, have dual cores which are easy to use and having Bluetooth and WiFi (transceiver radios) makes them easy to use. With Arduino, I was using nRF24L wireless boards and found them glitchy and the libraries not as stable as one might like. I pretty much gave up on them because one day, communications were perfect, then all of a sudden, without any logical reason, comms would just stop or get glitchy. I moved to the ESP32 and found that configuring communications (either using WiFi to the router or using peer-to-peer) was so easy and STABLE! Configuring the radios is so simple and you don't need a lot of code to do so. The only downside I see with this particular brand, is that when using the radios, the chip can get pretty hot. These manufacturers should offer a heat sink for the chip. When being enclosed in a case, this could be a problem, so adding a heat sink and MAYBE a tiny fan might be a good idea. All in all I do recommend these. I did end up buying more and intend to buy more yet. Review: I had to install the CP210x USB-to-serial driver to get Windows 10 to see the device on a COM port. Also, when the Arduino IDE started trying to upload my program to the board, when the IDE output said "Connecting...", I had to press the right pushbutton on the board, for a couple of seconds, in order to allow uploading to occur. Other than those two not-serious gotchas, the board seems to work as expected. (I tested getting chip info, doing an http get via WiFi, and deep sleep with timer wakeup.) The chip is reported as model ESP32-D0WDQ6 Rev 1. Both boards work fine. Update 2022-11-23: I bought two more boards for a total of four. All 4 have functioned well without any known reliability problems. (I'm using WiFi, digital GPIO usage, internal LED, flash updates, NVS changes.) THESE THINGS ARE GREAT! Update 2022-12-08: I bought two more boards. 6 out of 6 have worked flawlessly. I wrote custom motion sensor software using PlatformIO...flashing from PlatformIO works flawlessly OTA or wired. Every pinout has behaved as expected. Update 2024-10-13: I've purchased five batches of 2 boards (10 boards in total) over the past two years, and all of them have worked flawlessly. They are 38-pin narrow boards (25.4mm/1in wide), unlike many of the other boards that are 2.54mm/.1in wider than this one. So these fit nicely on a 400 point breadboard, leaving a usable wire point adjacent to each pin on both sides of the board after it's been seated into the breadboard. They have 4MB of flash storage. Excellent quality/value. ## Features - This module is safe, reliable, and scalable to a variety of applications. - The module has 38 pins and has more features than a 30-pin module. Narrower width, compatible with breadboard - Support Lua program, easy to develop. Support of three modes: AP, STA and AP + STA. - This board is used with 2.4 GHz dual-mode Wi-Fi and Bluetooth chips ESP-WROOM-32, as well as the 40nm low-power technology. - Technical Support: Our PDF tutorial is available on this page.

The pinout is wrong on this board so finding support for projects is nearly impossible. **Q: Where is a schematic? need to understand why some gpio pins don't work as expected. p0 and p19 don't work, p2 works but has an on-board blue led.** A: The PCB's silkscreen gpio is labeled different from the physical on-board gpio of the chip. **Q: Has anyone had any luck getting micropython onto this board?** A: Yes.

I have been able to power small projects with only using the USB port for power. They seem to be protected well cause even with hot swapping, shorting out or reverse polarity they just reboot and keep on truckin. ## Frequently Bought Together - KeeYees ESP32S ESP32 Development Board 2.4 GHz Dual Core WLAN WiFi + Bluetooth 2-in-1 Microcontroller ESP-WROOM-32 Chip for Arduino (38PIN Narrow Version, 2PCS) - 12PCS MG90S Servo Micro 180Β° 9G Servo Motor Geared Micro Servo Motor 9G Smart Robot Compatible with Raspberry Pi Project Car Helicopter Airplane Boat (180 Rotating) - TWTADE 10Pcs Single Linear Rotary Seal Amplifier Potentiometers Type 10k Ohm Knurled Shaft 3Pin RK097N-3-10K --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.uy/products/259376362-keeyees-esp32-oled-wifi-kit-esp-32-internet-development-board](https://www.desertcart.uy/products/259376362-keeyees-esp32-oled-wifi-kit-esp-32-internet-development-board) --- *Product available on Desertcart Uruguay* *Store origin: UY* *Last updated: 2026-04-23*
