Luckfox Lyra PLC – A Linux-based Rockchip RK3506B industrial controller with RS232, RS422, RS485, CAN bus, and relays

Luckfox Lyra PLC is a Linux-based programmable logic controller powered by a Rockchip RK3506B tri-core rm Cortex-A7 SoC, equipped with dual Ethernet, WiFi 6 and Bluetooth 5.2 wireless connectivity, a 1.9-inch touchscreen LCD, and a range of I/Os. The I/Os are mostly exposed through two 11-pole terminal blocks with one RS232, two RS422/RS485, one CAN Bus, and two relays, as well as smaller connectors for I2C, GPIO, and debugging. The system can be powered via USB-C  (5V only), terminal block pins supporting 7V-24V DC input, or an optional PoE module.   Luckfox Lyra PLC specifications: SoC – Rockchip RK3506B CPU 3x Arm Cortex-A7 cores up to 1.2 GHz Arm Cortex-M0 real-time core GPU – 2D GPU only No VPU, no NPU System Memory – 512MB DDR3L Storage – 8GB eMMC flash Display – 1.9-inch touchscreen LCD with 320 x 170 resolution Networking 2x 10/100 Mbps Ethernet RJ45 ports 2.4 GHz Wi-Fi [...]
