Eight Serial Ports HAT 2-Layer Stackable for Raspberry Pi

8-SERIAL Ports for Raspberry Pi: The latest versions of the Raspberry Pi have up to four UART ports on the GPIO connector, but you cannot use them without a physical layer transceiver.  The Eight Serial Ports HAT uses all four ports of the Raspberry Pi, plus eight additional ports from two 32-bit ARM Cortex processors, to implement all the standard serial ports in use today. The processors talk to the Raspberry Pi using only the I2C port, with the hardware address selectable from a DIP switch. One LED for each port shows when the port is active.

Eight Serial Ports HAT Specifications

RS485 Ports: Max 921,600 bps
RS232 Ports: Max 230,400 bps
RS422 Ports: TBD
1-Wire: TBD
CAN: TBD
M-BUS: TBD

Compatibility: The Eight Serial Ports HAT is compatible with Raspberry Pi versions from 3 to 5. Older versions of the Raspberry Pi might not have all four serial ports available on the GPIO connector.

Power Requirements:  The card takes 5V and less than 100mA of power from an external 5V power supply. It also provides up to 3.5A power through the hardware watchdog to the Raspberry Pi.

Stacking Multiple Cards: Two Eight-Serial-Port HATs can be stacked on top of one Raspberry Pi, implementing 16 serial ports.

Shipping Policy

FAST DELIVERY! We ship worldwide via FedEx, UPS, DHL, and USPS because they’re Fast, Reliable, Affordable, and Easily Trackable. We process orders in 24 hours; delivery may take 4 to 7 days or sooner, depending on your location. Once shipped, you will receive an email with your tracking number.

Ships From: Not all our products are shipped from the USA; we ship some from regions like China, Taiwan, or Europe. Therefore, the tariff you will pay will differ depending on which country your order will be shipped from because not all countries charge the same amount. For example, if the US imposes a 30% tariff on goods from China, other countries may impose a much lower tariff. Check the "Ships From:" label on this product page to see from which country we will ship it.

TARIFF: While not all products require a tariff, some may require a minimal or no tariff. If applicable, the buyer will pay the tariff within their respective country. The total amount of your order does not include a tariff. Please enter a reachable phone number during checkout so the Shipping Company can contact you to pay the tariff once your parcel arrives at your destination.

Why don't we add tariffs to the product's retail price? If all countries imposed the same tariff amount and used the same currency, we would have added the tariff amount to the product price. However, we do not do that because each country charges a different amount and uses a different currency, while some do not even charge a tariff. Therefore, we can't add a tariff to the product's retail pricing. Oz Robotics' manufacturing partners, or suppliers are not responsible for tariffs. We will not cancel your order or refund you if you do not pay the tariff. More Details.

SHIPPING COSTS: For some industrial products, e.g., heavy wheels, CNC machines, etc., the shipping cost is calculated based on the product weight, not quantity. For lower shipping costs for orders with multiple items, please email us at sales@ozrobotics.com before you buy. We show shipping rates on the product page under the SHIPPING tab. To see the shipping cost for your country, click add to cart on the product page.

PRODUCT DATASHEET AND MANUAL: If applicable, the Product Documentation, such as the Datasheet, CAD Design, STP Files, Manuals, Reference Materials, and Tutorials, will be available for download upon purchase from the My Account as needed. On the checkout page, please create an account to download product-related files upon purchase. You won’t be able to download otherwise.
