M5Stack CoreS3 SE IoT Controller w/o Battery Bottom
M5CoreS3 SE is a lightweight version of the third-generation CoreS3 main unit within the M5Stack development kit lineup. It operates on the ESP32-S3 solution and features a dual-core Xtensa LX7 processor, running at 240 MHz. With built-in (2.4G) WiFi, it includes 16MB FLASH and 8MB PSRAM for ample program storage. Downloads can be made via the Type-C interface, which supports OTG and CDC functions, allowing for easy USB device connectivity and firmware updates. The device features a durable 2.0-inch capacitive touch IPS screen protected by a high-strength glass panel.
Differences Between M5Stack CoreS3 and M5Stack CoreS3 SE
The M5CoreS3 SE utilizes the AXP2101 power management chip along with a 4-way power flow control circuit designed for efficient low power consumption. It also features an onboard MicroSD card slot and a BM8563 RTC chip, ensuring precise timing and sleep-timer functionalities. For audio output, it includes a high-fidelity 16-bit I2S amplifier chip AW88298 along with a built-in 1W speaker. For audio input, it has an ES7210 audio decoding chip with dual microphone inputs.
The device is equipped with an independent power button and a reset (RST) button, both featuring a built-in delay circuit. Long-pressing the reset button allows users to enter program download mode. This product is ideal for IoT development, various DIY projects, smart home control systems, and industrial automation control systems.

- 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.
Effective Date: September 16th, 2025
