: KEYESTUDIO mega prototype pcb boards are solderable breadboards with the same size as our regular mege board, and with the same connections to pins and power rails. You can not only directly solder the components on the top surface of mega to complete various prototype circuits, but also can paste mini breadboard to complete various circuit experiments using jumper wires. Specification: - Dimension: 5x10 CM - Thickness: about 1.6MM - Quantity: 10 pieces - Material: High quality of glass fiber FR4 - Color: Black mask, silver tone, yellow pins label - Hole-pitch: 2.54 mm/ 0.1 inches - Hole-diameter: 1 mm/ 0.04 inches - Quality PCB boards for prototyping Package List: 10 x Prototyping Boards
