Excellent real-time performance and high reliability for multi-node printer setups. Specially treated PCB with immersion gold process for improved conductivity and welding reliability. USB Type-C interface with ESD protection and support for firmware upgrades via SWD or hardware DFU, ensuring stable operation. This V2.1 adapter board supports stable CAN bus connection for 3D printers, enabling long-distance data transmission with strong anti-noise capability, excellent real-time performance, and high reliability for multi-node printer setups. The PCB adopts an immersion gold process with brighter color and luster, forming a fine crystal structure that is easier to solder than traditional treatments. This improves conductivity, welding reliability, and long-term durability, while reducing stress for a smoother, more stable user experience. The USB Type-C interface is equipped with ESD protection to reduce the risk of static discharge damage to your hardware. It also supports convenient firmware upgrades for the motherboard via SWD or hardware DFU, helping you keep the system updated and maintain stable operation.
