Review: Great for DIY Projects and Microcontroller Beginners - These boards were how I first learned to use microcontrollers for DIY projects! intuitive to use, has a plethora of pins, and are cheap enough to just buy more if you fry them or need more of them. Also, the ESPNOW communication built into the boards has a very short latency and has been easy to set up between two boards in my experience, which was a big help for some of my wireless projects. Review: These work nicely, but can get very warm with WiFi use. - 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. ## 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.

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.

Also, the ESPNOW communication built into the boards has a very short latency and has been easy to set up between two boards in my experience, which was a big help for some of my wireless projects. ### ⭐⭐⭐⭐⭐ These work nicely, but can get very warm with WiFi use. *by B***L on 1 March 2023* 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.

They work just fine. I like the little sticky tapes with the pin names on them. A few tips: 1) For those that complain about pressing the right-hand button to start an upload in the Arduino UI, this is very common, not a quirk in these particular boards. Not a big deal, really. Watch your sketch compile, then when it starts to upload, press the right-hand "boot" button for a few seconds. In my case, I hold the button until I see upload progress start, then let go. Nothing to it. 2) The on-board blue LED is connected to D2, by the way. Try the "blink" sketch first, and just change the default pin name or number to 2 instead of whatever the sketch default is. 3) When deciding what flavor of ESP32 board to select in the Arduino UI, I just use the generic "ESP32 Dev Module" and everything works fine for me. I have several other ESP32 modules, like the WROOM, and they all work with the Dev Module selection for me. Easy. 4) I also tried the very simple Wi-Fi server that can flash the on-board LED (no external connections needed) by going to Examples/WiFi/SimpleWiFiServer. Change the default pin 5 to pin 2 in several places, and then put in your home Wi-Fi SSID and your password. Enable the serial monitor for 115200 bps, and upload it. Once it connects, the ESP32 will tell you what its IP address is. Enter that IP address (like 192.168.1.123) in your phone or computer web browser, and you'll get a simple page coming from your ESP32 (which is now an HTTP server). The page tells you something like "click here to turn LED D2 on" (assuming you edited your sketch so that it says "D2" instead of D5) and a similar line to turn the LED off. Nothing to it, and you did this with zero hardware! 5) My modules did not have any labeling or silkscreen on them, but the included sticky labels are just fine. I stuck one set on the bottom of one module, and on the connector edge of the other. They are sticky enough that I'm not worried about them falling off. I really like these units, and will definitely buy more! I also bought a pair of the KeeYees breakout boards with screw terminals, and they perfectly match the pinout of these 38pin modules. ## 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.jp/products/259376362-esp32-oled-wifi-kit-esp-32-internet-development-board-0](https://www.desertcart.jp/products/259376362-esp32-oled-wifi-kit-esp-32-internet-development-board-0) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-04*
