Quick Summary (TL;DR):For a dedicated Home Assistant Bluetooth Proxy in 2026, the ESP32-C3 is the best-value Wi-Fi proxy: it is cheap, tiny, widely available, has Bluetooth 5 LE, 400 KB SRAM and more than enough CPU for continuous BLE scanning…
Quick Summary (TL;DR):The ESP32-S3 and ESP32-P4 can both run displays, cameras, LVGL and embedded AI workloads, but they are aimed at very different ceilings. The ESP32-S3 is the better all-in-one wireless MCU: dual-core Xtensa LX7 up to 240 MHz, 512…
Quick Summary (TL;DR):The ESP32-H2, ESP32-H21 and ESP32-H4 are all low-power Espressif chips built around Bluetooth LE + IEEE 802.15.4 rather than Wi-Fi. The H2 is still the safest choice today for mature boards, Arduino support and proven Thread/Zigbee development. The…
Quick Summary (TL;DR):The ESP32-S31-Function-CoreBoard-1 and ESP32-S31-Korvo-1 use the same new ESP32-S31 platform but target very different kinds of development. The Function-CoreBoard-1 is the better general-purpose S31 development board: it is built around ESP32-S31-WROOM-3, exposes most useful GPIOs on a 40-pin…
Quick Summary (TL;DR):The ESP32-S31 and ESP32-P4 overlap in HMI, AI, display and camera projects, but they are not really the same class of chip. The S31 is a high-performance connected MCU: dual-core RISC-V up to 320 MHz, 2.4 GHz Wi-Fi…
Quick Summary (TL;DR):The ESP32-S31 is the real next-generation successor to the ESP32-S3, but that does not mean every S3 project should immediately migrate. The S31 moves from dual-core Xtensa LX7 at 240 MHz to dual-core 32-bit RISC-V at up to…
