I'm curious, when choosing a microcontroller for IoT projects, which one do you usually invest in? Does the ESP32's Wi-Fi/BLE support and price-to-performance advantage appeal to you, or does the RP2040's dual-core architecture and compatibility with the Raspberry Pi ecosystem seem more attractive? Why do you think that way? What are your experiences?
Which one do you prefer, ESP32 or RP2040?

Which one are you using, ESP32 or RP2040? When I'm working on something, I first look at the connectivity features I need, like Wi-Fi/BLE on the ESP32. That's really important for me. What about your use case?
ESP32 is my go-to buddy because wireless connections like Wi-Fi and BLE are a must in IoT projects. For example, when sending sensor data from a home automation system to your phone, ESP32 lets you communicate directly over Wi-Fi using the MQTT protocol. RP2040 is great for local processing, but for wireless communication, you either need to add a module or deal with cables all the time, which can be a hassle.
Also, the price-to-performance ratio is excellent. For a simple Home Assistant project, ESP32 modules can go as low as $5-$10, making them super affordable. With RP2040, you get dual-core efficiency, but most projects need communication with multiple devices, so you’re stuck with limited options without Wi-Fi/BLE support. So, my choice is clear: ESP32 not only makes projects easier but also keeps future possibilities wide open.
I definitely prefer the ESP32, especially for IoT projects. With built-in Wi-Fi and Bluetooth Low Energy support, wireless communication becomes super easy—perfect for sending sensor data to the cloud or controlling things via a mobile app. Plus, it’s quite affordable; you can find variants for as low as $5 to $10. While the RP2040’s dual-core design and Raspberry Pi ecosystem compatibility are appealing, IoT projects usually need more connectivity-focused features. The RP2040 has its own advantages (like higher processing power), but for me, the ESP32 is the more practical choice.
Another big plus is how well the ESP32 works with popular platforms like Arduino and MicroPython, which speeds up development a lot. I’ve tried the RP2040 in small projects—especially for real-time applications—and it works well, but for most of my projects that require network connectivity, I still go with the ESP32. If you’re working on an IoT project that needs Wi-Fi or Bluetooth, the ESP32 is definitely the more convenient option.
