ESP32-C3 single core, cost-effective RISC-V MCU with WiFi and BLE 5.0 key aim was to be a replacement for ESP8266 - easy to upgrade existing ESP8266 to ESP32-C3 cheap smart home and office devices
ESP32-S series (ESP32-S2, ESP32-S3) - upgrade from the ESP32 - new and faster LX7 processor architecutre - more security features - on-chip AI capabilities - secure & low power use cases
ESP32-S2 - single core
- upgrade from the ESP32
- secure & low power use cases
ESP32-S3 - dual-core - aimed at AI and AIoT - offline voice recognition - computer vision - wake word detection - multi-dimensional human machine interface Example: ESP32-S3-Box AI Voice development kit
ESP32 Family Feature Grid As mentioned from: Adafruit Blog: ESP32 Family Feature Grid I struggle to remember the differences among the original ESP32 and the subsequent S2, S3 and C3 Series microcontrollers. Was going to carefully assemble a feature grid to organize this, and share it here on the blog…but as it turns out Espressif already has a fantastic one, I just didn’t think to look here. It’s perfection! And long!
