PCB size: 145 mm x 111 mm (excluding connectors) SMD components are already soldered, enabling quicker setup and testing Magnetic ring must be wound by the user; the PCB provides a printed indication of the number of turns for each magnetic ring Net weight: 142 g Benefits and considerations Readytouse base for rapid prototyping: the SMD components are presoldered, reducing initial assembly time Clear guidance on coil winding: the PCB provides a printed indication of the required number of turns for winding the magnetic ring Clear specifications on a compact, stable platform: large enough for practical coil designs while remaining portable Use scenarios Inductor or transformer prototyping for RF or power electronics projects, where you wind the magnetic ring to the printed turn count for customizing the coil Educational or training setups to teach coil winding, inductance concepts, and magnetic circuit design using a handson PCB Test bench or lab workstation for validating magnetic component behavior before final production, with builtin winding guidance to ensure consistency
