The larger size PCB board prototype kit includes 1 piece of 3.5x5.9 inch (9x15cm) board, 2 pieces of 2.8x3.5 inch (7x9cm) boards, as well as 3 pieces of 2.0x2.8 inches (5x7cm) and 5 pieces of 1.6x2.4 inches (4x6cm) 1.2x2.8 inches (3x7cm), and 0.8x3.1 inches (2x8cm) boards to meet various project requirements.The thimble set consists of 6 straight male needles, 6 straight female needles, and 4 right angle pin female needles with each row containing 40 pins spaced at intervals of 0 .1 inch (2 .54mm).Terminal are inclusive of six sets of twopin terminals, four sets of threepin terminals, along with a hundred standard jumper caps with a pin pitch board spacing at the standard measurement of 2 .54mm.These rugged and PCB boards are constructed from highquality FR4 fiberglass material that is both robust and resilient, measuring at a thickness of 1 .6mm.Featuring a convenient design, each board is equipped with four mounting holes in the corners for easy assembly. Pretinned holes on the circuit board simplify component and sensor soldering for seamless project integration.Colour:As ShownMaterial:PCBPackage Contents:1x Circuit Board Prototype KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
