USB Driver for M5Stack Core2 V1.1

Prior to usage, visit the download page to obtain the USB driver suitable for your operating system. Note that M5Stack Core2 features two versions with the CH9102F A USB chip, enabling the installation of compatible drivers (CH9102) for proper operation of both IC versions.

Power Management

Power Operations:
To power on, press the left button once.
To turn off, hold the left button for 4 seconds.
Use the RST button at the bottom for a reset.

Module Expansion and Compatibility

When stacking with M5 modules, remove the battery at the bottom of the M5Stack Core2 V1.1. If retaining I2S microphone, IMU, and battery functions is needed, consider using the M5GO Bottom2. The PCB accommodates connections for the CH910F chip and lithium battery.
The internal vibration motor may interfere with M5 Base series modules and should not be stacked with them to avoid damage.
For screens with touch nonlinearity at the edges, try upgrading the firmware using M5Tool.
Note, the device includes a non-replaceable battery.

USB Driver

Download the appropriate driver for your operating system using the link below. There are two versions of driver chips available; the CP34X driver package supports the CH9102 version. After decompressing, select the installation package that matches your OS bit version. If unsure which USB chip your device uses, installing both drivers is advisable. When installing CH9102_VCP_SER_MacOS v1.7, any error messages can be ignored as the installation completes successfully. If you experience programming issues (e.g., timeout or "Failed to write to target RAM"), you might need to reinstall the USB driver.

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

For products stored in our warehouse in the U.S., we use either USPS or UPS for shipping, depending on the size of the package. Logistics within U.S. are very efficient, with an estimated delivery time of 3-7 business days, ensuring you receive your order quickly and conveniently.  

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. 

To ensure that your order is delivered within your desired timeframe, we recommend reviewing the warehouse information provided on the product pages before placing your order and selecting the appropriate shipping option. If you have any questions or need further assistance, please don't hesitate to contact our customer support team—we are here to help you!   

 

4. Customs and Taxes

4.1 How are customs handled by OpenELAB for import or export?

For shipments delivered to customers in the United States, OpenELAB will clearly declare the value of the goods on the customs form in compliance with U.S. Customs and Border Protection (CBP) requirements. Depending on the product value and origin, certain orders may be subject to import duties, taxes, or brokerage fees upon arrival, which are the responsibility of the recipient unless otherwise stated.
 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?

OpenELAB collects U.S. state sales tax where legally required. The applicable rate depends on the shipping address and will be calculated at checkout.
 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?

Apart from sales tax, OpenELAB may charge shipping or handling fees, which will be clearly displayed before checkout.
 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.
