Raspberry Pi Pico vs ESP32: Which Microcontroller Is Right for You?


The lines are curved because at short intervals the loop() wake-up is the dominant effect while at long intervals the broadcast packet wake-up becomes dominant. Here the esp32 performs much better than the esp8266 primarily because it reliably goes back to light-sleep. In addition, its power save listen interval is 5x as long and it goes to sleep more rapidly after waking up. The lines that go off the top of the chart are for deep-sleep with periodic wake-up using an insecure open access point. Deep-sleep without crypto uses the least power of all options when iteration times exceed a few seconds.

  • Once it’s done, insert the microSD card into your board, connect it to a display, USB keyboard and mouse, and optionally your Ethernet router.
  • It is the successor to the ESP8266 which is also a low-cost Wi-Fi microchip albeit with limited vastly limited functionality.
  • These are among the cheapest Wi-Fi microchip or modules that you will find in the market.
  • Second, we all know that none of them actually manufactures a volume MCU in the US.

The ESP8266 is capable of either hosting an application or offloading all WiFi networking functions from another application processor. With the complete and self-contained Wi-Fi networking capabilities, ESP8266EX can perform either as a standalone application or as the slave to a host MCU. When ESP8266EX hosts the application, it promptly boots up from the flash. The integrated high-speed cache helps to increase the system performance and optimize the system memory. Also, ESP8266EX can be applied to any microcontroller design as a Wi-Fi adaptor through SPI/SDIO or UART interfaces.

Programmable I/O or PIO, for short, allows you to add extra communication interfaces and even create new interfaces. This feature is completely absent in the ESP32 and can be a sticking point especially if you are an advanced hardware hacker who needs to connect to legacy hardware. Programmable I/O is an incredibly powerful feature, and you should consider opting for the Raspberry Pi Pico if you need it in your projects.

It’s not as newbie-friendly as ESP-Arduino, for sure, but it’s a ton more powerful, and we’re totally happy to leave the ESP8266 SDK behind us. One of these things is not like the otherIf you were confused by the chip’s name, like we were, a week or so playing with the new chip will make it all clear. The ESP32-C3 is a lot more like a reduced version of the ESP32 than it is like an improvement over the ESP8266, even though it’s probably destined to play the latter role in our projects. If you count in the new ESP32-S3 that brings in USB, the ESP32 family is bigger than just one chip.

If you’re not sure which one to choose, we recommend starting with the ESP32. It’s a great all-around device that will give you the most flexibility for your project. The ESP32 is a versatile chip that can be used for a variety of applications. The ESP32 has built-in SPI RAM that can be used to store data. The ESP8266 does not have built-in SPI RAM and thus needs to use an external SPI RAM chip.

RISC-V: Power and Speed

In my professional life I always had the luxury of kicking up the computationally difficult things to the system-on-chip and let a proper superscalar CPU take on the tough problems. Where things got dicey was a touch screen sensor that had to preprocess the data in order for it to fit in the narrow bandwidth of the pipe upstream. Although it is missing a few functions, it is adequate for the vast majority of straightforward DIY IoT applications. The GPIO mapping, however, has significant restrictions, and there might not be enough pins to accomplish your goals.

If you need a more powerful microcontroller for your project, the ESP32 is the better choice. The ESP8266 is easier to use than the ESP32, but it’s not as powerful. The ESP32 is more versatile and can be used for a wider range of applications, but it’s not as easy to use. The ESP8266 was released in 2014 and quickly became one of the most popular microcontrollers on the market. The ESP32 was released in 2016 and has since become a popular choice for IoT projects.

How far can ESP8266 transmit?

The ESP8266 is an integrated circuit with 16 GPIO pins and different peripherals like Serial peripherals interface, Integrated circuit protocol, Analog to digital converter. Esp8266 can support multiple SSL if you customize the firmware but ram is limited. With close to 4x as much ram and hardware crypto engine esp32 should support many more.


Overall, ESP32 is much more suitable for programming than ESP8266. SSL support refers to the support of Transport Layer Security protocol which is used to secure communication over a network. So, if you need advanced peripherals in your device then ESP32 is the better choice.

These esp32 vs esp8266 typically include a central processing unit , memory, input/output (I/O) interfaces and often a radio frequency transceiver. SoCs are very common in the mobile phone industry because they allow manufacturers to pack all the necessary components for a complete phone onto a single chip. This saves space and highly increases the efficiency of mass production. If you’re just getting started with microcontrollers, the ESP8266 is the better choice.

It means that all or most components of a computer are integrated into a single chip. In this case, the computer isn’t powerful enough to run Windows. But it’s made to run custom firmware that we can, for example, create using Arduino.

The https://traderoom.info/ power also creates secure socket layer connections and great essential requirements in the world of IoT. The ESP32 gives you remote control access and a temperature sensor. The ESP32 offers you the security of Secure boot flash encryption 1024 – bit OTP with PWM 16.

Heck, you can’t buy an ESP32-C3 module yet anyway, so we’re stuck looking into our crystal ball a little bit. But the murmurs about pricing similarly to the ESP8266 make us take notice, and it’s certainly a worthy upgrade even at a small price premium, if that’s what the market will bear. At the same time, the ESP32-C3 is fundamentally less capable than the ESP32, so it’s got to come in cheaper than that. With ESP8266 dev boards selling for $2 and ESP32 dev boards selling for $4, that doesn’t leave much wiggle room, and we suspect some folks will just pony up for the ESP32s. So it’s hard to say how much the price really matters anyway. The ESP8266 started life as a simple AT-command-set WiFi modem, and a bunch of hackers proved that it had a lot more to offer.

Several open-source projects are now available on the Internet, which can be assembled in just a couple of hours. The Raspberry Pi Pico is a great board for those who have never used one before and are looking to get started with microcontrollers. Also, if you’re already in the Raspberry Pi ecosystem, then the Raspberry Pi Pico might be a better option just to fit the motif. I don’t get the hype around the pico either, but it’s fine to want a board with no wireless. S3 will be Tensilica still, as we spent some time to add AI instructions and other fanciness to it.

  • The ESP8266 and ESP32 are made for use in wearable electronics, the IoT industry, and mobile devices, and you’ll find plenty of well-documented projects based on either around the web.
  • Microcontroller programming is usually done in assembler or C, although there are compilers for other languages, such as microPython or Lua.

This will enable you to connect your device to various other devices without any problems. In this section, we will compare the peripherals offered by both modules. Peripherals are essential components of any electronic device. You will have to sacrifice the power cost for the performance.

The ESP32 consumes more power than the ESP8266, which can be a problem if you are using batteries to power your project. The CC3200 is a Wi-Fi and Bluetooth combo chip that is supported by the SimpleLink™ SDK. It offers developers more flexibility with the types of applications they can develop. The chip also includes an on-chip security encryption module.
