Wireless-Tag has put the WT32P4C5-43S (also labelled ZX4D30CE405-V1.3) on its store: a 4.3-inch capacitive touch development board that pairs an ESP32-P4 application SoC with a separate ESP32-C5 (or, in some listings, ESP32-C61) wireless module. CNX Software covered it on 11 October 2026; Esp32.co.uk followed on 13 October. The base kit is listed at $32. Stock is thin: Wireless-Tag told CNX that an LCD shortage leaves little inventory now, with new stock around mid-November, and Esp32.co.uk still saw the page marked sold out or pre-order on 13 October.
Hardware
The ESP32-P4 handles graphics and cameras. It has no built-in Wi-Fi, so the companion radio supplies dual-band 2.4/5 GHz Wi-Fi 6, Bluetooth LE and IEEE 802.15.4 (Zigbee / Thread on C5 silicon). The panel is an 800 × 480 IPS touchscreen at about 500 cd/m², driven over an 18-bit parallel RGB bus with a Hynitron CST3240 touch controller. Around it: a 15-pin MIPI CSI-2 camera connector (Raspberry Pi CSI style), a microSD slot, USB-C High-Speed for power and application USB, a second USB-C for debug/JTAG, a 14-pin GPIO header and separate 7-pin debug headers for both chips. Overall size is about 117 × 81 × 16 mm.
Earlier Wireless-Tag P4+C5 boards needed an external display. This one is a turnkey HMI slab aimed at industrial panels, smart control surfaces and edge vision terminals. Confirm which wireless module is fitted before you buy: the store title says C5, while some copy mentions C61 configurations.
Software caveat
You program it with ESP-IDF 6.x (and Arduino / LVGL per the vendor). Wireless-Tag publishes separate GitHub trees for the P4 host BSP and the C5/C61 companion firmware, including an ESP-Hosted path over SDIO. Neither CNX nor Esp32.co.uk mentions ESPHome. For a Home Assistant wall panel, budget firmware work; this is not a flash-and-forget ESPHome board yet.
