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 […]
