ESP32, and the Raspberry Pi Pico go head-to-head in this real-world benchmark using Arduino to see which microcontroller performs better in both speed and energy efficiency. Using the same Arduino/C++ code to calculate π with 100,000 iterations, we test the Pico at 133 MHz and 240 MHz (overclocked) against the ESP32 at 240 MHz — and the results might surprise you. The Raspberry Pi Pico doesn’t just keep up — it beats the ESP32 in performance and uses 51% less energy to complete the same task. If you're building an embedded project where Arduino compatibility, raw performance, or low power matter — and you don't need Wi-Fi/Bluetooth — the Pico is a seriously underrated option. 🛒 Boards Used in This Video: 🔗 Raspberry Pi Pico: 🔗 ESP32 Dev Board: 🔗 Power Meter: Timestamps ⏱️ 00:00:00 - Intro 00:00:35 - Specs 00:01:55 - First Test @133MHZ 00:03:04 - Second Test @240MHz 00:04:00 - Power Consumption 00:04:29 - Results Table #ESP32 #Arduino #ESP32Projects #raspberrypi #raspberrypipico
