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 project requirements. The thimble set consists of 6 straight male needles, 6 straight female needles, and 4 right angle pin head female needles with each row containing 40 pins spaced at intervals of 0 .1 inch (2 .54mm). Terminal are inclusive of six sets of two-pin terminals, four sets of three-pin 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 high-quality 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. Pre-tinned holes on the circuit board simplify component and sensor soldering for seamless project integration.<br><br>Colour:As Shown Material:PCB<br><br>Package Contents: 1x Circuit Board Prototype Kit<br><br>Only the above package content, other products are not included.
