For most new ESP32 and Home Assistant projects, the SHT40 is the best value: it is newer, smaller, faster, and consumes less power than the SHT31 while offering slightly better humidity accuracy. Choose the SHT45 when measurement accuracy matters most…
For most Home Assistant rooms, the LD2410 is still the best all-round mmWave presence sensor because it is inexpensive, mature, highly configurable and particularly good at detecting a person who is sitting or barely moving. Choose the LD2450 when you…
The ESP32-C6-DevKitM-1 is a compact development board based on the ESP32-C6-MINI-1 or MINI-1U, combining 2.4 GHz Wi-Fi 6, Bluetooth LE, Zigbee and Thread. For general GPIO use, good starting pins are GPIO0, 1, 2, 3, 6, 7, 14, 18, 19,…
The ESP32-C5 is Espressif’s first ESP32 with dual-band 2.4 GHz + 5 GHz Wi-Fi 6, while also providing Bluetooth LE and 802.15.4 for Zigbee and Thread. It combines a 240 MHz RISC-V main processor, a 48 MHz low-power RISC-V processor,…
If you work with ESP32 boards, Arduino modules, sensors, small PCBs or Home Assistant DIY electronics, there comes a point where a normal soldering iron is not enough. A soldering iron is fine for pin headers, wires and simple connectors.…

ESP32-C5 DevKitC-1 v1.2 pinout diagram with header tables, safe GPIOs, strapping pins, USB, UART, ADC, RGB LED and revision notes.
The LD2410 is one of the most useful sensors you can connect to an ESP32 for Home Assistant. It is a 24GHz mmWave presence sensor, which means it can detect small human movement and stationary presence much better than a…
An ESP32 AC climate controller is one of the best upgrades you can make to an ordinary infrared-controlled air conditioner. Instead of using the original remote control every time, you can let Home Assistant turn the AC on, change the…
