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…
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,…
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…
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…
An ESP32 + CT current clamp + ESPHome can monitor AC current without electrically connecting the ESP32 to mains voltage. ESPHome’s native ct_clamp component samples the CT waveform, calculates RMS current and exposes it directly to Home Assistant. For a…
The M5Stack PaperS3 is a complete ESP32-S3 e-paper development device built around an ESP32-S3R8 dual-core 240 MHz processor, 16 MB flash, 8 MB PSRAM, a 4.7-inch 960 × 540 e-ink display, capacitive touch, microSD, RTC, BMI270 IMU, buzzer and an…
