Comparisons between FireBeetle ESP32, ESP8266, ESP32 C6, and ESP32 S3

DFRobot Sep 25 2023 9882

Welcome to the FireBeetle ESP32, ESP8266, ESP32-C series, ESP32-S series IoT Microcontroller selection guide. Through this guide, you can get a detailed understanding of the application of Espressif SoC and the comprehensive resources of the FireBeetle series development boards.

 

This document is divided into two parts:

Part 1: Introduces the comparison of Espressif’s chip series. Through comparison, you can clearly understand the positioning of Espressif’s chips, so you can quickly choose the chip series needed for the project.

Part 2: Introduces the detailed parameter comparison of FireBeetle series MCU. Through comparison, you can directly choose the development board required for the project.

 

If you are first exposed to ESP32, it is recommended to choose FireBeetle 2 ESP32-E Microcontroller (with Header) and Gravity: IO Shield for FireBeetle 2. The ESP32-E MCU has a lot of tutorials suitable for beginners to learn, and the expansion board is more convenient for wiring. FireBeetle 2 ESP32-E development board (with Header) has a wealth of tutorials and project cases, widely used by makers, and the development board is equipped with a USB to serial burning chip, making code burning simpler. FireBeetle 2 ESP32-E IoT microcontroller (with Header) has already soldered the pin header, so it can be used directly when you get it. With Gravity: IO Shield for FireBeetle 2, you can easily connect various sensors.

 

Part 1: Comparison of Espressif chip series

ESP32 series: The ESP32 series is Espressif’s classic SoC, supports Bluetooth and Wi-Fi, has rich tutorials, can refer to many projects, suitable for beginners to learn and IoT projects.

ESP32-C series: The ESP32-C series is a low-power, high-cost performance SoC launched by Espressif. This series is all RISC-V cores, supports various wireless connections, and is suitable for IoT projects. Currently, this series includes ESP32-C3, ESP32-C2, ESP32-C6, ESP32-C5, ESP32-C61.

ESP32-S series: The ESP32-S series is a high-performance SoC launched by Espressif, with a wealth of peripherals, suitable for human-computer interaction, AIoT and other projects. This series currently includes ESP32-S2, ESP32-S3. ESP32-S3 is Espressif’s first SoC that supports AI acceleration. It can use vector instructions through the ESP-DSP and ESP-NN libraries to achieve high-performance image recognition, voice wake-up and recognition applications.

ESP32-P series: The ESP32-P series is a new series released by Espressif in 2024. This series currently includes ESP32-P4. ESP32-P4 is Espressif’s first non-Wi-Fi or Bluetooth SoC, driven by a high-performance dual-core RISC-V processor, with AI instruction extensions, advanced memory subsystems, and integrated high-speed peripherals, fully meeting the higher requirements of the next generation of embedded applications for human-machine interface support, edge computing capabilities, and IO connection characteristics.

ESP32-H series: The ESP32-H series is a low-power, secure link chip launched by Espressif. This series all support Thread and Zigbee, suitable for building Thread border routers and Zigbee bridges with other SoCs, connecting Thread and Zigbee devices with Matter Wi-Fi networks. Currently, this series includes ESP32-H2, ESP32-H4.

ESP8266 series: ESP8266 is Espressif’s first SoC for IoT scenarios, integrated with Wi-Fi. Espressif no longer recommends using it, and suggests using the ESP32-C series as a replacement.

Part 2: FireBeetle comparison

An important distinction to note in the FireBeetle series is the difference between the first and second generation. While both generations have their unique strengths, key differences lie in the chips they utilize and their physical characteristics. The second-generation FireBeetle products are more compact in size and feature different chips compared to their first-generation counterparts. Moreover, due to changes in size and pin layout, the expansion boards of the two generations are not interchangeable. These differences in chip selection and physical design not only broaden the range of use-cases and potential applications, but also underscore the uniqueness of each FireBeetle generation.
