ESP32-C5 dual-band WiFi 6 and Bluetooth LE IoT board features 1.47-inch color LCD

ESP32-C5-LCD-1.47 board

We’ve covered plenty of connected displays based on ESP32 chips over the years, but the Waveshare ESP32-C5-LCD-1.47 is a little different, since it’s the first to feature an ESP32-C5 chip for dual-band WiFi 6 connectivity. It’s basically based on the ESP32-C6-LCD-1.47 design, but replaces the ESP32-C6 supporting 2.4 GHz WiFi 6 with an ESP32-C5 capable of handling both 2.4 GHz and 5 GHz WiFi 6. Other features mostly remain the same: a 1.47-inch 262K-color display with 320 x 172 resolution, 4MB of flash, an RGB LED, a microSD card slot, and two 9-pin headers for GPIO expansion. Waveshare ESP32-C5-LCD-1.47 specifications: Wireless MCU – Espressif Systems ESP32-C5FH4 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip Storage – 320 KB ROM, 4MB flash Wireless Connectivity Dual-band (2.4GHz/5 GHz) 802.11ax WiFi […]

DESLOC V150 Plus smart lock integrates a perovskite solar panel, supports 3D face recognition (Crowdfunding)

DESLOC V150 Plus Low Light Self Charging Solar Smart Lock

DESLOC V150 Plus is a smart lock with an integrated perovskite solar panel, which can generate power under low-light conditions, eliminating or at least reducing the need for manual battery charging. The V150 Plus is a two-part system consisting of exterior and interior units connected via wires through the door. The exterior unit includes the perovskite solar panel, two cameras with a 3D facial recognition system, and an AI-assisted fingerprint sensor, while the interior unit houses a 10,000mAh removable battery, a Battery Management System (BMS), and a lock motor. The BMS manages battery charging and power distribution. The rechargeable battery is rated to provide up to 8 months of backup operation when solar charging is unavailable, which is a little longer than the Lockzo AL501 3-in-1 smart door lock we reviewed earlier. DESLOC V150 Plus specifications: SoC – TBD (most probably a chip from Nordic or Espressif) Connectivity – Wi-Fi and Bluetooth Access […]

Makerfabs MaTouch ESP32-P4 TFTTouch 10.1 MIPI with 4G LTE is an ESP32-P4 + ESP32-C6-based display development platform for HMI edge AI, and connected embedded applications. The development board features a 10.1-inch IPS LCD, very similar to those of Seeed Studio’s reTerminal D1001, Waveshare ESP32-P4-WIFI6-Touch-LCD, and CrowPanel Advanced 7-inch displays. However, what makes it unique compared to other devices is that it also features a SIM7670G 4G LTE modem with a SIM card slot, an RJ45 Ethernet jack, and a 2MP camera. The HMI display also comes with microphone and speaker connectors, a microSD card slot, various USB interfaces, lithium battery support, and two 2.54 mm pitch GPIO expansion headers exposing UART, I2C, SPI, and other peripheral interfaces. All these features make it suitable for HMI, edge AI, and connected embedded applications.

GEEKOM A7 2026 Edition Review – Part 2: AMD Ryzen 5 7545U Mini PC tested with Windows 11 Pro

GEEKOM A7 2026 Edition Windows 11 Pro review

We have already checked out the GEEKOM A7 2026 Edition mini PC’s hardware with an unboxing and a teardown in the first part of the review, before quickly trying the pre-installed Windows 11 Pro. We’ve now had time to test the AMD Ryzen 5 7545U mini PC more thoroughly in Windows 11, and we’ll report our experience, including feature testing, benchmark results, 4K and 8K YouTube video playback, 2.5GbE and WiFi 6E network performance evaluation, and cooling performance, as well as fan noise and power consumption measurements.

SpacemiT K3 Pico-ITX RISC-V Chassis Kit Review – Part 2: What works, what doesn’t in Bianbu OS 4.0

SpacemiT K3 Pico-ITX Chassis Kit BianbuOS 4.0 review

Last month, I received the SpacemiT K3 Pico-ITX Chassis Kit based on the company’s K3 16-core RISC-V SoC, and started the review with an unboxing, a teardown, and a first boot to Bianbu OS 4.0. Since the system features a 10Gbps Ethernet SFP+ cage, I also had to order a 10GbE SFP+ to Copper adapter, as my 10GbE networking gear is exclusively based on RJ45 ports. In this review, I’ll check system information in Bianbu OS 4.0.1, run a few benchmarks, test 10GbE, GbE, and WiFi 6 networking performance, play YouTube videos at various resolutions, run AI workloads (LLM), check all/most features work as expected, and measure the power consumption of the SpacemiT K3 “Pico-ITX Chassis Kit” mini PC. It’s a fairly long review, so if you are short on time, you can check out the “what works, what doesn’t” section. Bianbu OS 4.0 System Information Before running anything, I […]
