DescriptionThe M5Stack Base26 is a 26mm universal functional base for the M5Stack 5 x 5cm system. This functional base integrates a 9-24V to 5V DC-DC circuit, two Grove expansion ports, one HT3.96-4P interface, a side M12 through-hole, three side SMA antenna through-holes, and a 2.54mm prototype area for custom circuit work. The M5Stack Base26 functional base also includes an RS485-to-TTL adapter board that can be soldered to enable PWR485 through HT3.96-4P. The M5Stack Base26 supports DIN rail, wall, screw, and bottom M12 connector fixing, so this functional base fits compact industrial prototype development without changing the 5 x 5cm stack format.Features M5Stack Base26 26mm functional base for M5Stack 5 x 5cm projects. Built-in 9-24V to 5V DC-DC circuit with MP1584 conversion chip. Two Grove expansion ports for sensor, actuator, and custom accessory wiring. HT3.96-4P interface and included RS485-to-TTL adapter board support PWR485 communication. 2.54mm prototype hole area for adding custom circuit functions. Side M12 through-hole and three side SMA antenna through-holes for enclosure routing. DIN rail, wall, screw, and bottom M12 connector mounting options.
