Base26 V1.1



Base26 V1.1 is a "5x5cm system" universal functional base, the thickness of the product is 26mm (excluding the busbar pin header), including 9~24V to 5V DCDC circuit, 2 custom Grove expansion ports, 1 VH3.96-4P interface, 1 side opening M12 vias, 3 side opening SMA antenna vias, and the 2.54mm pitch hole plate area in the center of the PCB, users can independently add circuit functions. One RS485 to TTL conversion board is included in the kit, which can be soldered by the user to realize the PWR485 function through VH3.96-4P. A variety of fixing methods are reserved in the structure, supporting DIN rail, wall mounting, screw fixing, and bottom M12 connector fixing. This product is mainly used for customers to customize the function base. (Customers can contact the official for in-depth customization)
