M5Stack ATOMIC Motion Base v1.2 with Power Monitor (INA226AIDGSR)
The M5Stack ATOMIC Motion Base v1.2 with Power Monitor (INA226AIDGSR) is an advanced drive base designed specifically for the Atom control series, offering high-performance capabilities for both servo and DC motors. This base is engineered to incorporate power management, intelligent expandability, and safety features that make it an all-in-one solution for diverse development projects. It includes 4-channel servo ports and 2-channel DC motor ports, allowing for precise control of various actuators. Additionally, the two HY2.0-4P interfaces facilitate quick connections to multiple sensors, such as those for measuring temperature, humidity, and light levels, enhancing the functionality of your devices with ease.
The communication protocol is based on stable I2C technology, leveraging STM32 combined with RZ7899 control chips to ensure reliable performance, efficient data transmission, and minimal latency.
For its power supply, the system features a rechargeable 900mAh lithium battery that meets the 18350 specification. It is safeguarded by the DW01-A high-precision lithium battery protection chip, which offers comprehensive safety features including overcharge, overdischarge, and short-circuit protection. The INA226 chip provides real-time monitoring of voltage, current, and power to maintain stable operation. Furthermore, the base includes overload protection and a user-friendly charging mechanism. With an independent power switch and a removable battery design, it ensures both safety and convenience during use.
The M5Stack ATOMIC Motion Base v1.2 is ideal for applications where safety, adaptability, and portability are key requirements.

- For products stored in the Shenzhen warehouse, we will ship them directly from Shenzhen, China.
- If you place an order for products from both the U.S. warehouse and the Shenzhen warehouse, we will ship your order separately: the products from the Shenzhen warehouse will be sent from Shenzhen, and the products from the U.S. warehouse will be sent from the U.S. warehouse.
3. International Warehouse
Our products are stored in both our U.S. and Shenzhen warehouses to provide more flexible logistics solutions tailored to different regions and customer needs. On each product's description page, we indicate the specific warehouse location to help you better plan your purchase and delivery schedule.
3.1 U.S. Warehouse
3.2 Chinese Warehouse
We will only arrange YunExpressexpress shipping from Shenzhen for orders with products in the Shenzhen warehouse worth more than €50. Orders directly shipped from our Shenzhen warehouse are handled by YunExpress. Given the complexities of international shipping, the estimated delivery time for these packages is around 10 business days, though this may vary slightly due to customs processes or other uncontrollable factors. Otherwise, the products will first be shipped from China to our U.S. warehouse and then shipped to the final destination.
4. Customs and Taxes
4.1 How are customs handled by OpenELAB for import or export?
We aim to minimize delays and ensure compliance, but OpenELAB does not guarantee exemption from U.S. customs charges.
4.2 Are U.S. sales taxes included when the Customer places an order?
If no sales tax is charged at the time of purchase, you may still be responsible for use tax according to your state’s tax laws. OpenELAB is committed to complying with the U.S. Supreme Court's decision in South Dakota v. Wayfair, Inc. and applicable local regulations.
4.3 Are there any other fees besides tax?
Please note that international shipments to the U.S. may occasionally incur customs clearance charges or carrier-imposed fees (e.g., by DHL, FedEx, or USPS). These charges are not controlled by OpenELAB and may vary based on the delivery carrier and U.S. import classification.
