Raspberry Pi Pico vs ESP32

Advertisement

You can get the Raspberry Pi Pico on Amazon for just under $4 plus shipping costs. The much older ESP32 you get in various forms for just under $10. You see, you get the ESP32 for a little more money with additional sensors or a display to display sensor data (or even the IP address of the microcontroller) or a camera. On the Raspberry Pi Pico, there are quite new chip RP2040 installed which was developed under the ARM license. The ESP32 chip from Espressif is much elder. Here is a table which will give you some information to compare.

Differences in programming ESP32 & Pi Pico

 

If you have flashed the ESP32 with the firmware for MicroPython, you can program it with MicroPython. Thus, you can operate both microcontrollers with the same programming language. As a development environment, the various IDEs for MicroPython are available here:

  • MU Editor,
  • Thonny,
  • Eclipse IDE,
  • uPyCraft

However, you can also flash the ESP32 for ESP Easy and thus there is no programming and you can easily configure the sensors & actuators via a website. You can use Arduino IDE for both of them :

Differences in powering ESP32 & Pi Pico

 

ESP32 needs a thoughtful, well-researched power supply. Pi Pico can operate from 1.8 to 5.5 V. A Li-Ion battery or 2 x AA batteries can be directly connected to Pi Pico.

Final Thought

 

If I had to choose between a Raspberry Pi Pico and an ESP32, I would resort to the latter. As already mentioned, the ESP32 has clear advantages over the Pi Pico due to the Bluetooth & WiFi interface. But the Pico is much cheaper, i.e. for low-cost projects without Bluetooth or WiFi this is ideal. Raspberry Pi Pico is for children while ESP32 is a powerful, low-cost microcontroller that is used in some products. Arduino Uno consumes a low amount of power but it has the slowest processor.
