Giveaway Week 2025 – Elecrow Pi Terminal Raspberry CM4 industrial HMI display

Elecrow CrowPanel CM4 Pi Terminal Demo application

Sometimes we receive samples even though we did not ask for them, said we would have time to review them, or due to miscommunication. That’s exactly what has happened with the Elecrow Pi Terminal, a Raspberry Pi CM4-powered industrial HMI with a 7-inch touchscreen display. So instead of letting it go to waste, I decided to offer it as the second prize of the CNX Software Giveaway Week 2025 contest. Elecrow Pi Terminal specifications: SoM – Raspberry Pi CM4 Lite SoC – Broadcom BCM2711 CPU – Quad-core Cortex-A72 SoC @ 1.5GHz GPU – VideoCore VI with support for OpenGL ES 3.1 and Vulkan 1.0 VPU Decode – H.265/HEVC up to 4Kp60, H.264 up to 1080p60 Encode – H.264 up to 1080p30 Memory – 4GB LPDDR4-3200 Storage – N/A Wireless – Dual-band WiFi 5 and Bluetooth 5.0 Storage 64GB microSD card preloaded with the Raspberry Pi OS + Node-RED software M.2 […]

Supermicro ARS-E103-JONX-H2 fanless Arm embedded system is powered by NVIDIA Jetson Orin NX

Supermicro Arm embedded system edge ai server

Supermicro is better known for its x86 servers, and they have already produced higher-end Arm-based servers like the Ampere-based MegaDC product line, but no compact Arm servers so far. The ARS-E103-JONX-H2 embedded system, featuring an 8-core Arm CPU, four gigabit Ethernet ports, and a 10GbE RJ45 port, is almost that, but not quite. Instead, it’s another NVIDIA Jetson Orin NX-powered fanless embedded PC for imaging, industrial automation, digital signage, retail, healthcare, and other Edge AI applications. It also features three M.2 sockets for storage, wireless, and cellular connectivity, an HDMI 2.0 video output, four USB 3.2 ports, two RS232/RS485 connectors, and a terminal block with digital inputs and outputs. Supermicro ARS-E103-JONX-H2 specifications: System-on-Module – NVIDIA Jetson Orin NX CPU – 8-core Arm Cortex-A78AE processor GPU – 1024-core NVIDIA Ampere GPU with 32 Tensor Cores System Memory – Up to 16GB RAM AI Performance – Up to 157 TOPS in “Super” […]

Geniatech XPI-3576 – A Rockchip RK3576 SBC with “extended credit card” form factor

Geniatech XPI-3576 is another Rockchip RK3576 SBC with up to 16GB RAM, up to 128GB flash, a M.2 Key B+M socket for storage or AI accelerator, HDMI 2.1 video output, MIPI DSI and CSI connectors, Gigabit Ethernet, WiFi 5, Bluetooth 5.0, a few USB ports, a 40-pin GPIO header, and a terminal block with RS232, RS485, and CAN Bus interfaces. Genatech launched the XPI family in 2018, starting with the XPI-S905X single board computer, which follows the Raspberry Pi 3 form factor. Since then, all other XPI boards leverages Raspberry Pi Model B or Zero form factors, but the XPI-3576 is a little different, as the Rockchip RK3576 board is based on what I would call an “Extended Credit Card” form factor (125 x 56mm), enabling extra features such as a proper M.2 2280 socket, while keeping compatibility with (most) Raspberry Pi HATs. Geniatech XPI-3576 specifications: SoC – Rockchip RK3576 CPU […]
