What ESP32 to buy & use? ESP32 S2,S3,C3,C6,H2...

The ESP32 line of electronic products has become  a mainstream platform for makers & industrial   applications. But, in the last few years,  Espressif have been releasing a ton of different   application-specific ESP32 SoCs. So much so  that it has become super confusing to choose   the right Espressif SoC for your application.  In this episode of 5 Minute Tech Takes we solve   this confusion once and for all! Let's start with the ESP32-H2. ESP32-H2   is the first ESP32 Chip that started to  embrace other wireless protocols. On top of   WiFi & BLE connectivity it adds Thread and Zigbee  protocols available. Furthermore, the combined   availability of ZigBee and BLE connectivity  enables building devices for the Matter protocol,   which intends to bring interoperability for  smart-home devices across different ecosystems.   Also, this SoC comes with an integrated  DC-DC converter that enables ultra-low-power,   energy-efficient operation. Thus,  ESP32-H2 is best suited for the   following applications. * Smart-Connected Devices   from Different Ecosystems. * Thread border routers/Zigbee   Gateways /Matter Border routers * Ultra - low power industrial applications   Now let's talk about the two SoCs in the ESP32-C  Series. Namely ESP32 C6 & C3. ESP32-C3 is a   single-core Wi-Fi and BLE 5 SoC, based on the  open-source 32-bit core RISC-V. This is the   first RISC based SoC from Espressif, and the  key aim was to be a replacement for ESP8266.   It is multiple times more secure than ESP8266,  It supports BLE 5 with long Range mode support;   It consumes way less power, larger memory and more  stable support with ESPIDF than ESP8266. Espressif   claims it's super easy to migrate from ESP8266 to  ESP32-C3. So now the potential applications are.   * Upgrade existing ESP8266 line-up  of products you already sell   * Consider this over ESP8266 if you are building  Smart Home or Smart Office products   Now let's look at the ESP32-C6. It's just  ESP32-C3 on steroids. Well on steroids in   terms of connectivity, I mean. The ESP32-C3 has  Wi-Fi 4 while the ESP32 C6 replaces that with   Wi-Fi 6 capabilities while maintaining backward  compatibility. It's already certified by Wi-Fi   Alliance out of the box. That is one less thing  to worry about for a developer. WiFi 6 is faster,   low power, secure, reliable, and more devices can  be connected at the same time, which is essential   for IoT. So now the potential applications are. * Creating Future Proof Smart Devices   * Industrial Applications where a  lot of devices are involved   Finally lets look at the two ESP32 SoCs in the  S series. The ESP32 S Series is like a direct   upgrade to the mainstream ESP32 lineup. The  upgrades include Faster Processor Architecture,   More Security, & On chipAI Capabilities. Let's  look at the ESP32 S2 SoC first. The ESP32-S2 is   a low-power, single-core Wi-Fi SoC, designed  to be secure and cost-effective, with a high   performance and a rich set of IO capabilities. The  ESP32 S2 comes with a more powerful RISC-V Based   ULP Coprocessor along with the newer Single Core  Main Processor. The lack of a dual-core processor   is somehow balanced by the faster single-core  LX7 Architecture core. ESP32 S2 is also capable   of dynamically turning off the Wi-Fi when not in  use to save power. These 2 features make it highly   energy efficient. It also provides a lot of new  hardware-based security features. So where can   ESP32S2 be used? If your application does not  need the power of dual cores to do FreeRTOS,   but would benefit a lot from the cool security  and power features of S2, you can replace the   ESP32 with an ESP32 S2. So in a way Just like  how ESP32 C3 is a replacement for ESP8266,   ESP32 S2 aims to be a replacement for ESP32. Now lets finish off by discussing the ESP32 S3.   ESP32 S3 is specifically aimed at AIoT Products.  It's an upgraded ESP32 S2 with dual-core processor   Xtensa 32-bit LX7 clocked at up to 240 MHz, and  features AI vector instructions, as well as a   reliable security encryption engine. Developers  can take advantage of these vector instructions   through ESP-DSP and ESP-NN libraries to optimise  their applications. ESP-WHO and ESP-Skainet SDKs   will also support this acceleration. The  ESP-32-S3 series modules can also handle   high-speed Octal SPI flash & PSRAM making AI  applications much smoother. Use cases include:   * Offline Voice Recognition Applications * Computer Vision Application   * Wake Word Detection applications * Multi Dimensional Human Machine Interface   We have come to the end of the video, and you can  like and share the video if you found it useful.   Also, don't forget to subscribe to  Chip In Detail for more such videos.
