ESP8266 vs ESP32: when the little one is (not) worth it
Real differences between the ESP8266 and the ESP32, what each costs, where the 8266 still makes sense, and why today the ESP32-C3 beats it almost every time.

ESP32-P4 in depth: the radio-less ESP32 for displays and high performance
Everything about the ESP32-P4: two RISC-V cores at 400 MHz, 768 KB SRAM, 55 GPIOs, MIPI-CSI/DSI, USB 2.0 HS and Ethernet. No Wi-Fi or Bluetooth: pair it with a C6.
ESP32-H2 in depth: the Wi-Fi-less ESP32 for battery Matter nodes
Everything about the ESP32-H2: low-power RISC-V, 320 KB SRAM, 19 GPIOs with ADC, BLE 5 and 802.15.4, no Wi-Fi, and why that is an advantage in smart homes.
ESP32-C6 in depth: Wi-Fi 6, Matter and Thread in one chip
Everything about the ESP32-C6: dual RISC-V core, Wi-Fi 6, BLE 5, 802.15.4 radio (Thread/Zigbee/Matter), USB Serial/JTAG, pinout and when it is the right choice.
ESP32-C3 in depth: the one I recommend to start with (and why)
Everything about the ESP32-C3: RISC-V, BLE 5, USB Serial/JTAG, its 22 GPIOs, the ADC, pinout, where it falls short and why it is the best starter buy.
ESP32-S3 in depth: cores, PSRAM, AI and USB for serious projects
Everything about the ESP32-S3: two LX7 cores, BLE 5, USB OTG, vector instructions for AI, quad vs octal PSRAM, camera, pinout and when it is worth it.
