ESP32-C5 devkit offers 2.8-inch capacitive touch display, dual-band Wi-Fi 6, Bluetooth 5 LE, LiPo battery support

Last week, I wrote about the ESP32-C5-LCD-1.47 as one of the first ESP32-C5 devkits with a built-in display enabling dual-band WiFi 6 connectivity for IoT and HMI projects. However, one reader lamented the lack of touch-capable screens, at which point kwchow pointed to the ESP32-C5-Touch-LCD-2.8 model offering just that by pairing an ESP32-C5 with a 2.8-inch IPS display with capacitive touch and 320×480 resolution. The new board also features a microSD card slot, a USB-C port for power and programming, a built-in microphone and a speaker connector, a few sensors, and various I/Os connectors for expansion. Let’s have a closer look. ESP32-C5-Touch-LCD-2.8 specifications: Wireless module – Espressif Systems ESP32-C5-WROOM-1-N32R8 SoC – ESP32-C5HR8 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, 8MB PSRAM Storage – 320 KB ROM Wireless […]

Khadas Mind Graphics 2 review – A powerful NVIDIA GeForce RTX 5060 Ti eGPU dock for the Mind 2 mini PC

Earlier this month, I received the Khadas Mind 2 (Intel Core Ultra 7 155H) mini PC with two accessories connecting through the Mind Link (PCIe x8) connector: The Mind xPlay Display and Keyboard combo, and the Mind Graphics 2 dock, adding a range of interfaces and an NVIDIA GeForce RTX 5060 Ti GPU with 16GB of VRAM. After going through the specifications, an unboxing, and a partial teardown in the first part of the review, I tested the Mind xPlay using the Mind and Mind 2 mini PCs running Windows 11 and Ubuntu 24.04. I’ve now had time to test the Khadas Mind Graphics 2 dock with the Mind 2 mini PC running Windows 11, so I’ll report my experience with the NVIDIA GPU (3D graphics and AI), and test all features, including 2.5GbE networking, the built-in speakers, microphone array, and so on. A few gremlins and system info When […]
