Waveshare ESP32-P4 Smart 86 Box Features WiFi 6, Ethernet, and touchscreen, fits into 86×86 mm junction box

Waveshare’s ESP32-P4 Smart 86 Box is a touchscreen controller designed for Smart Home and Industrial IoT applications, with a compact 86×86 mm form factor that fits standard junction boxes.

The device is available in two variants – the ESP32-P4-WIFI6-Touch-LCD-4B with a 4-inch 720×720 touchscreen, ESP32-P4 module, MIPI CSI camera connector, and 28-pin GPIO header; and the ESP32-P4-86-Panel-ETH-2RO, which adds RS485, 2x relays, 10/100Mbps Ethernet, and 6V-30V DC input. It includes 32MB Flash, 32MB PSRAM, a microSD slot, a USB-C port, an ES8311 audio codec, a microphone, a speaker header, and RTC battery support. Applications include a smart home control panel for managing lights, HVAC, curtains, and security systems, or as an industrial HMI for machine control through RS-485 and relays.
