ESP32 ESP32-C3 ESP-WROOM-32 Development Board Kits, 15 GPIO CH340 Micro USB WiFi + Bluetooth Dual Cores Microcontroller Processor Compatible with Arduino IDE NodeMCU

I was never able to get the RGB to light up although an LED attached to pin 8 does work using Arduino IDE. The schematic shows no RGB LED in it nor does it show any CH340 USB chip. I never got Serial.println working with this board. If any one has facts to change my opinion I am all ears. Lastly, the USB port was mounted a bit crooked but the connections remained soldered so I was able to flash the board. EDIT: After buying this board and not being able to get RGB LED to light I bought an Espressif C3-Mini board. I was not able to blink its RGB LED with Arduino. I hunted down an tutorial for blinking RGB LED using ESP-IDF and found one on Instructables. I followed the instructions there and was able to get RBG LED to blink on both of these boards. The appearance of the manufacturing of the board still seems a bit sloppy but the seller offered me a refund (thank you for that) after this review first posted, so that is why I gave it four stars instead of just three.

As a hobbyist, i can never get enough of these types of devices. This one works well for monitoring the status of something that didn't come with any smart home integrations, and it seems to be working reliably.

It's a C3 with a "DevKitM-1" PCB layout. Good if you have an expansion board or existing project and want/need a similar MCU with plug-n-play compatibility. Other than that, it's on the pricier side for what it actually is. You can find more capable ESP32 MCU clones for less, but most likely won't have ESP32-C3-DevKitM-1 pinout compatibility. Good if you need it, better options available if you don't.

This ESP32 mini board works well. I'm using it with an MCP2512 module for CAN bus work. So far the two are working fine together and I have no complaints. You can see in the pictures, that the antenna hangs off the edge of the board and is exposed. On other minis I've seen, the antenna is within the footprint of the board, so keep this in mind when choosing a container for it.

This seems like a reasonable, albeit basic, ESP32 board. It does what it’s supposed to and is offered at a good price. However, I'm a bit disappointed that it still uses micro-USB in 2024—USB-C would have been a much better choice for modern convenience. Despite that, it’s a capable ESP32 board that should work well for most projects. If you don’t mind the older USB connection, it’s a solid option.

I recently acquired this Development Board. The price is very reasonable for the quality and functionality you get. It’s a fantastic deal for anyone working on electronic projects. The board works as intended and seems to function perfectly. It has been reliable and effective in all my applications. This Development Board is great for various electronic projects. It integrates seamlessly and provides a stable platform for development, making it a valuable addition to my toolkit. Overall, the Development Board is an excellent purchase. With a decent price, reliable performance, and suitability for electronic projects, it’s perfect for anyone looking to enhance their projects. Highly recommended!

ESP32-C3 mini board worked as expected. No issues while testing it out. Works with ESPHome, etc. For just a couple of bucks the price is fine since you do not have to wait 3 weeks for them to arrive from overseas and handy to have for various projects.

I'm using this little esp32 as a simple ESP-NOW hub for a small home automation project, and I love it! It's very compact, easily powered, compatible with the Arduino framework, and affordable. There are plenty of pins to connect a few devices and a small display, and the built-in wifi antenna has more than enough range to communicate with other ESP devices around my home (about 800 sq ft.).
