The ESP32 WROOM-32 dev board with USB-C — the board most Home Assistant and WLED projects are actually built on. Dual-core, WiFi and Bluetooth, and enough GPIO to do something useful.
We buy these in quantity for our own installs, which is why they're sold in multipacks here. If you're building anything with ESPHome you will use more than one — the first is a prototype, the second is the one that goes in the wall, and the third is the one you keep because the second is now inaccessible behind plasterboard.
What people build with these
ESPHome sensors — temperature, presence, energy, water, anything with an I2C or 1-Wire part on the end
WLED controllers — drives WS2812 and WS2815 addressable tape directly
Relay and switch control — local MQTT, no cloud
Modbus and RS485 bridges — inverters, BMS units, energy meters
Flashes straight from Arduino IDE, PlatformIO, ESPHome or the web flasher — no button-holding gymnastics on the USB-C boards.
