⚡ LILYGO T-Halow P4: M.2 Board with ESP32-P4 and WiFi HaLow

LILYGO has released the T-Halow P4, a compact M.2 2280 development board integrating the ESP32-P4 microcontroller, an ESP32-C6 wireless co-processor, and a Taixin TX-AH WiFi HaLow module. This configuration targets long-range wireless connectivity needs within constrained form factors. The board measures 80 x 22mm and utilizes an M.2 B-key connector to expose GPIO pins and interfaces for integration into custom carrier boards.

The core SoC is the Espressif Systems ESP32-P4NRW32X, featuring a dual-core RISC-V CPU running at 400 MHz with AI instruction extensions and a single-precision FPU. It also includes a single-core RISC-V low-power MCU operating at up to 40 MHz. Memory resources comprise 768 KB of HP L2MEM, 32 KB of LP SRAM, 8 KB of TCM, and 32MB of external memory. Graphics capabilities include a 2D Pixel Processing Accelerator and a VPU supporting H.264 and JPEG codecs.

Video processing supports hardware H.264 encoding at up to 1080p30, alongside MIPI CSI camera and MIPI DSI display interfaces. These features position the T-Halow P4 for applications such as compact IoT gateways, remote cameras, and industrial monitoring systems. The combination of the ESP32-P4, ESP32-C6, and WiFi HaLow module provides a versatile platform for embedded developers requiring specific wireless protocols and video handling in an M.2 footprint.
