Quick Summary (TL;DR):ESP RainMaker Neo, announced by Espressif on 5 August 2026, is an open-source device-to-cloud-to-phone IoT platform for ESP32 products. It is much more than an ESP32 library: the Neo stack includes the device firmware SDK, AWS serverless cloud…
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…
Quick Summary (TL;DR):For most people building a Matter, Thread or Zigbee project in 2026, the ESP32-C6 is still the best all-round starting point: it combines a mature 160 MHz RISC-V platform, 2.4 GHz Wi-Fi 6, Bluetooth LE and IEEE 802.15.4…
Quick Summary (TL;DR):For most new Home Assistant + ESPHome projects in 2026, the ESP32-C6 is the best default choice: it is inexpensive, mature, supports 2.4 GHz Wi-Fi 6, Bluetooth LE and IEEE 802.15.4 for Zigbee/Thread, and has enough CPU and…
Quick Summary (TL;DR):The ESP32-C3 SuperMini is a tiny third-party ESP32-C3 board built around a 160 MHz single-core RISC-V processor with 2.4 GHz Wi-Fi, Bluetooth LE, native USB and usually 4 MB flash. On the common 16-pin layout, the easiest GPIOs…
Quick Summary (TL;DR): The ESP32-P4 Function-EV-Board v1.5.2 is not a normal ESP32 DevKit. It is a high-performance multimedia development platform built around the dual-core 400 MHz ESP32-P4 RISC-V processor, with 16 MB flash, 32 MB PSRAM, MIPI CSI camera, MIPI…
