Seeed Studio XIAO ESP32C3 RISC-V Wi-Fi BLE 5.0 Battery Charge Supported
The Seeed Studio XIAO ESP32C3 is a compact IoT development board featuring the Espressif ESP32-C3 WiFi/Bluetooth dual-mode chip. This board integrates a strong 32-bit RISC-V CPU, providing impressive computational capabilities thanks to its efficient design. It boasts excellent radio frequency performance, supporting both IEEE 802.11 b/g/n WiFi and Bluetooth 5 (BLE) protocols. An external antenna is included to boost the signal strength for various wireless applications. The board features a compact and elegant form-factor, along with a single-sided surface-mountable design. It offers an array of interfaces with 11 digital I/O that can function as PWM pins and 3 analog I/O that serve as ADC pins. The device supports four serial interfaces, including UART, I2C, and SPI. Additionally, there are small buttons for reset and bootloader mode integrated on the board.

- 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.

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.
