Product description: Atomic Motion Base v1.2 - power and control base for Atom series modules - M5Stack A090-V12
The Atomic Motion Base v1.2 is an advanced power and control base designed for robotic and mobile projects using Atom series controllers. Integrated STM32 and RZ7899 chips enable precise control of four servos and two DC motors , while two 4-pin connectors with a 2mm pitch allow for quick connection of environmental sensors such as temperature, humidity, and light. Power is supplied by a replaceable 18350 Li-Ion 900mAh battery , supported by a dual protection system: the DW01-A chip protects against overcharging, discharging, and short circuits, while the INA226 chip monitors voltage, current, and power in real time. With overload protection, a power switch, and a magnetically mounted design, the Atomic Motion Base v1.2 combines functionality with safety and ease of use.
