+# Luckfox PicoKVM
+Luckfox PicoKVM is a lightweight IP KVM operation and maintenance tool. It allows remote access to a target device’s display and simulates HID input over the network, enabling contactless operation and management of development boards, PCs, and servers. The product delivers stable, low-latency video capture and remote control, making it well-suited for scenarios such as remote computer management and server maintenance. The software is based on a secondary development of JetKVM.
