⚙️ ATOMIC Motion Base v1.1 – Servo & DC Motor Driver with Power Monitor (INA226AIDGSR) The ATOMIC Motion Base v1.1 is a servo and DC motor driver base designed for the ATOM controller series. It provides 4 servo channels and 2 DC motor interfaces, plus two Grove interfaces for easy sensor and expansion connectivity. Communication is handled via I2C protocol, with an integrated STM32 controller chip ensuring stable data transmission. For power, it includes a detachable 18350 lithium battery (900mAh) and integrates an INA226 current/voltage detection chip to monitor battery voltage, current, and power in real time. Additional features include overload protection (5V@5A), battery charging function, and an independent power switch. Its magnetic back design enhances portability and usability in robotics, prototyping, and automation experiments. 🌟 Features Compatible with ATOM series controllers 4‑channel servo control 2‑channel DC motor control Detachable lithium battery (18350, 900mAh) Magnetic back design Independent power switch 2 × Grove interfaces for expansion Chargeable battery with monitoring Real‑time battery current/voltage detection Development platforms: UIFlow 1.0, UIFlow 2.0, Arduino IDE UIFlow 1.0 UIFlow 2.0 Arduino IDE 📦 Includes 1 × ATOMIC Motion Base v1.1 ⚙️ Applications DC motor car control Servo robotic arm control Robotics development Smart device prototyping Automation experiments 📐 Specifications Specification Parameter DC Motor Driver RZ7899 Power Detection Chip INA226 Charge/Discharge Chip ETA9740 Overload Protection 5V@5A Detachable Lithium Battery 18350@900mAh Motor Interface Pin Pitch 2.54mm Full Load Steering Current 3A Peak Current per Motor 1A Peak Current per Servo 0.4A Standby Current (Switch On) [email protected] Charging Current [email protected] Grove Interface HY2.0-4P Operating Temperature 0-40°C ATOMIC Motion Base v1.1 Size 74.0 x 24.0 x 20.7mm Packaging Size 77.0 x 30.0 x 26.0mm ATOMIC Motion Base v1.1 Weight 41.1g Packaging Weight 44.8g ATOMIC Motion Base v1.1 Schematicss Atomic Motion Base v1.1 Schematics PDF ATOMIC Motion Base v1.1 Pinmap I2C Interface Atomic Motion Base v1.1 SDA SCL ATOM Lite / ATOM Matrix G25 G21 ATOMS3 / ATOMS3 Lite G38 G39 ATOMS3R / ATOMS3R-CAM / ATOMS3R-M12 G38 G39 HY2.0-4P Grove Interface Atomic Motion Base v1.1 PORT-B (Black) PORT-C (Blue) ATOM Lite / ATOM Matrix G33/G23 G19/G22 ATOMS3 / ATOMS3 Lite G8/G7 G6/G5 ATOMS3R / ATOMS3R-CAM / ATOMS3R-M12 G8/G7 G6/G5 STM32 STM32F030F4P6 PA10 PA9 PA4 PB1 PA6 PA7 PA0 PA1 PA2 PA3 I2C SDA SCL DC Motor M1F M1R M2F M2R Servo Servo3 Servo1 Servo4 Servo2 ATOMIC Motion Base v1.1 Size ATOMIC Motion Base v1.1 Softwares Guide Atomic Motion Base v1.1 Arduino Guide Arduino Atomic Motion Base v1.1 Library Atomic Motion Base v1.1 Test Example UIFlow 1.0 Atomic Motion Base v1.1 Docs Atomic Motion Base v1.1 Example UIFlow 2.0 Atomic Motion Base v1.1 Docs and example ATOMIC Motion Base v1.1 Protocol Protocol Type: I2C I2C Address: 0x38 Function Reg Address Length Data Range R/W Servo(1~4) 0x00~0x03 1Byte MSB angle: 0-180 R/W Servo(1~4) 0x10、0x12、0x14、0x16 2Byte MSB pulse: 500-2500 R/W Motor(1~2) 0x20~0x21 1Byte MSB speed: -127-127 R/W ATOM Series: Compact and Versatile Controllers Difference Between M5Stack ATOM Echo, ATOM Lite, ATOM Matrix, ATOMU and ATOMS3 What is ATOMS3 and How Many Different Types Are There?
