【6 different sizes of pcb boards】 Products include: 96.29*75.14mm、84.85**64.53mm、77.88*57.38mm、65.47*45.28mm、74*36.44mm、85.25*26.92mm Pcb board, multi-size PCB board can meet your needs when designing your own Arduino kit, electronic experiments and DIY projects
【High-quality material】 Made of FR4 material, with high heat resistance,1.6mm thickness makes a very solid and sturdy prototype circuit board. Standard IC spacing is 2.54mm.
【Easy installation】 The four corners of the circuit board have mounting holes for easy assembly, and you can easily install any sensor and component to complete your project.
【Nickel plating technology】 Electroless nickel plating technology prevents the copper on the PCB from being oxidized and corroded, which is conducive to welding and contact.
【Wide application】 It's allow you to DIY welding, electronic experiments and other projects, but also suitable for Arduino, Raspberry PI and other programming boards.
