FSC-BT691 Bluetooth 5.1 Low Energy Small Size SoC BLE Module
FSC-BT691 is a Bluetooth Low Energy (BLE) 5.1 ultra-low-power and small-size SoC Module featuring a 2.4 GHz transceiver and an ARM Cortex-M0+ microcontroller. Its low active RF and MCU current consumption, along with low-power mode operation, ensure extended battery life, making it suitable for small coin-cell and energy-harvesting applications. The module includes easy-to-use firmware; developers can use simple UART AT commands to integrate Bluetooth functionality. It is designed for a wide range of applications, including disposables, wireless sensor nodes, beacons, proximity tags, trackers, trackpads, toys, and medical and industrial applications.

Shipping Policy
We ship directly from the country where the product is made, such as China, Italy, or Taiwan, helping you avoid or pay lower tariffs.
Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they are fast, reliable, and easily trackable. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We will email you the tracking number once your order is shipped. Our prices are in US dollars.
Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, shipping costs are calculated by weight rather than quantity. To reduce shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before placing your order. We show shipping rates on the product page under the SHIPPING tab. To view the shipping cost for your country, click 'Add to Cart' on the product page.
Return Policy
5 Hours: Mistakes happen when ordering, so you have 5 hours to request a refund for any reason, including if you don’t want to pay the tariff. However, Stripe will not refund you their processing fee if you cancel your order.
All Sales Are Final: After 5 hours, we cannot cancel your order or issue a refund because order cancellations incur multiple transaction processing fees from Stripe and PayPal, additional shipping fees, and reverse tariff payments, which are costly and time-consuming. For technical issues, we will be happy to assist you in resolving problems and provide a replacement if you can prove that the product has a manufacturing defect.
Exchange Policy: We want you to be happy with your new purchase. However, once you have used the product, we cannot issue a refund. However, we will offer an exchange for a product with irreversible manufacturing defects or technical issues. If you purchased the wrong product, then you, as the customer, will be responsible for the re-shipping fees and tariffs. If the product you purchased is defective, email us at support@ozrobotics.com with photos or a video of the faulty parts so we can evaluate the issue before arranging a replacement.

Terms and Conditions
If you were not at home or at your shipping address during the parcel delivery: It is not our or the supplier's fault; if the shipping/delivery company could not deliver your parcel because you, the customer, were not at home or at your delivery address on the delivery date/time, and as a result, the carrier returned your parcel to the manufacturer from where it was shipped. Please note that we do not accept excuses; you will therefore have to pay the re-shipping fee and the tariff for any re-shipment request. In such a case, we will not issue a refund. Please always check your SPAM folder to ensure you receive emails from Oz Robotics and shipping companies.
Product Warranty: Our warranty covers only product-related problems caused by manufacturing defects. It does not cover problems resulting from faulty repair attempts, customer accidents, or misuse.
