Tablet-like, ESP32-P4-based 7, 8, and 10.1-inch HMI displays integrate Wi-Fi 6 connectivity, 5MP camera

Waveshare has recently released the ESP32-P4-WIFI6-Touch-LCD, a family of tablet-like, fully enclosed HMI display development boards built around the ESP32-P4 SoC. The company offers 7-inch, 8-inch, or 10.1-inch configurations, all designed for industrial HMI, smart home terminals, and edge AI applications. Since the ESP32-P4 does not include built-in wireless connectivity, Waveshare has integrated an ESP32-C6-MINI module for WiFi 6 and Bluetooth 5 (LE) support. The board also leverages the ESP32-P4’s peripherals for MIPI CSI/DSI interfaces, a 5MP camera, and various I/Os, including USB 2.0 OTG and USB-to-UART Type-C ports, an SDIO 3.0 microSD card slot, dual microphones with echo cancellation, a speaker driven by an onboard audio codec, GPIO expansion headers, and optional battery support. Waveshare ESP32-P4-WIFI6-Touch-LCD specifications: Wireless module – ESP32-P4-Core SoC – Espressif Systems ESP32-P4NRW32 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core […]

reComputer Industrial R2135-12 review – A Raspberry Pi CM5-powered fanless Edge AI PC with Hailo-8 AI accelerator

Hello, today I am going to review the reComputer AI Industrial R2135-12 from Seeed Studio. This is an industrial edge computer built around the Raspberry Pi Compute Module 5 platform. The model is configured with 8 GB LPDDR4 memory and 32 GB eMMC storage. It provides a rich set of I/O options, including dual Gigabit Ethernet, USB 3.0/USB 2.0, HDMI output, and industrial interfaces such as RS-485/RS-232, CAN, and GPIO, along with Wi-Fi and Bluetooth support and a wide DC power input range suitable for industrial environments. In addition to standard checking and benchmarking the device, I will also include a hands-on demo application in which the system runs an AI model for real-time people detection from a USB camera, then sends detection results to an external ESP32 microcontroller to drive LED matrices for visually highlighting the locations of detected people. I made the following YouTube video to quickly demonstrate […]
