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…
The Wemos/LOLIN D1 Mini is one of the easiest ESP8266 boards to use because it combines a 4 MB ESP8266 module, USB programming, 3.3 V regulation and breadboard-friendly headers in a very small board. For most projects, the best GPIOs…
The ESP-01 and ESP-01S are tiny ESP8266 Wi-Fi modules with only eight pins, but they can run complete Arduino, MQTT and simple ESPHome projects without another microcontroller. The two easiest user GPIOs are GPIO0 and GPIO2, although both are also…
Choose the ESP32-C6 if the project needs Zigbee, Thread, Matter-over-Thread or the more complete smart-home feature set. It combines 2.4 GHz Wi-Fi 6 and BLE with an IEEE 802.15.4 radio, 512 KB HP SRAM and a separate 20 MHz low-power…
Choose the ESP32-C5 when connectivity is the priority: it provides dual-band 2.4 + 5 GHz Wi-Fi 6, Bluetooth LE, Zigbee, Thread, a 240 MHz RISC-V CPU, a 48 MHz low-power processor and optional PSRAM. Choose the ESP32-S3 when local processing…
The ESP32-C6 SuperMini is one of the smallest ways to get Wi-Fi 6, Bluetooth LE, Zigbee and Thread in an ESP32 project. On the common SuperMini layout, the easiest GPIOs to start with are GPIO0, GPIO1, GPIO2, GPIO3, GPIO14, GPIO20,…
The ESP32-C6 is the better choice for most new projects because it keeps the C3’s 160 MHz RISC-V architecture while adding Wi-Fi 6, Bluetooth 5.3, Zigbee, Thread, a separate low-power RISC-V core, more internal SRAM and a larger peripheral set.…
For most ESP32 and Home Assistant projects, the SHT40 remains the best-value choice. The SHT41 is essentially a tighter-tolerance SHT40: both have the same typical ±1.8% RH and ±0.2°C accuracy, but the SHT41 guarantees substantially better worst-case humidity accuracy across…
The ESP32-C5 is the more capable chip overall: it has a faster 240 MHz RISC-V CPU, dual-band 2.4 GHz + 5 GHz Wi-Fi 6, newer Bluetooth LE features, Thread 1.4, optional PSRAM and module configurations with much larger flash. The…
For most developers, the ESP32-C6-DevKitC-1 is the better board to buy. Both boards provide the same core ESP32-C6 features — 160 MHz RISC-V CPU, 2.4 GHz Wi-Fi 6, Bluetooth LE, Zigbee and Thread — but the DevKitC-1 uses the larger…
