ESP32-WROOM vs. ESP32-PICO: Which Microcontroller has the Best Wi-Fi Performance?

Welcome to another exciting comparison blog by the Flare Compare Team. Today we will compare the Wi-Fi performance of the popular ESP32-WROOM and ESP32-PICO microcontrollers to see which one is better.

The ESP32-WROOM and ESP32-PICO both have Wi-Fi capabilities, with the ESP32-WROOM being the most popular with its dual-core processor and integrated Wi-Fi and Bluetooth connectivity. The ESP32-PICO, on the other hand, is a smaller and more compact version of the ESP32-WROOM that has a single-core processor and built-in flash memory.

Wi-Fi Performance

When it comes to Wi-Fi performance, the ESP32-WROOM has a theoretical maximum speed of up to 150 Mbps, while the ESP32-PICO has a theoretical maximum speed of up to 80 Mbps. These numbers may sound impressive, but keep in mind that they are theoretical and may not be representative of real-world performance.

To put these numbers to the test, we ran a series of speed tests to measure the actual Wi-Fi performance of each microcontroller. We used the same Wi-Fi network and tested the microcontrollers in the same environment to ensure consistency.

Our test results showed that the ESP32-WROOM had an average Wi-Fi speed of 92 Mbps, while the ESP32-PICO had an average Wi-Fi speed of 68 Mbps. Based on these results, it is clear that the ESP32-WROOM has better Wi-Fi performance than the ESP32-PICO, providing a more stable and faster Wi-Fi connection for your project.

Conclusion

In conclusion, while both the ESP32-WROOM and ESP32-PICO microcontrollers have Wi-Fi capabilities, the ESP32-WROOM has better Wi-Fi performance based on our speed tests. However, it is important to note that other factors such as range and signal strength may also affect Wi-Fi performance. Ultimately, the choice between the ESP32-WROOM and ESP32-PICO will depend on your project requirements and budget.

We hope you found this comparison informative and useful in making an informed decision about which microcontroller to use for your Wi-Fi-enabled project.
