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

Easy to use. Needed the 38 pin version instead of the one with less pins. USB c is my go to as well now. Works well and worth the money.

Very versatile devices. I think I'll order another with a screen.

One of teh few variants where antenna is not shadowed by motherboard. Way better range than those.

Everything works well IF powered by USB-power, but wireless is unreliable if powered from an external voltage source. I have several of these devkit boards from different manufacturers which MOST work well enough but this one has given me some trouble. I'm still thinking that I might have a noisy source power or some other issue that causes this as the ESP32 shouldn't exhibit this behavior without reason.

These ESP32 boards are incredibly versatile and easy to work with. Built-in Wi-Fi and Bluetooth make them perfect for smart home and IoT applications. I had it up and running with the ESPHome integration in Home Assistant in minutes. Tons of community support and tutorials available. Highly recommended for hobbyists and developers alike!

2 of these work. The third is DOA. You plug in the USB cable and it draws too much power. One Anker charger tripped its internal circuit and shut down, the computer complains of USB overvoltage protection and a laptop charger turned itself off. The other 2 are fine.

Works, but to install the code, you must hold the boot button.

Es lo que esperaba para realizar un proyecto de monitoreo de calidad de aire mediante el uso de IoT.
