USB TTL is a Complete Plug-and-Play USB – UART interface solution developed with advanced CH340 chipsets. It has a standard 2.0 Type A (male) USB and Type C Micro USB connection, Power Selection Jumpers, and 6 PIN TTL Connectors. This USB TTL enables communication between serial UART and USB interfaces. It features an in-built USB-to-TTL Transfer chip and can be used in various USB-to-TTL electronic projects. The user may connect to the MCU thanks to its TTL interface output. This mini-module is designed for various applications. The CH340 and CP2102 modules support WIN7, VISTA, MAC, and LINUX (32—and 64-bit systems).
CH340 Variant:
CH340 is a USB bus converter chip that can convert USB to serial interface, IrDA infrared, or printer interface. In serial interface mode, CH340 supplies a standard MODEM liaison signal, which is used to enlarge a computer’s asynchronous serial interface or upgrade the standard serial device to a USB bus directly. In infrared mode, adding an infrared transceiver to CH340 can compose a USB infrared adapter and realize SIR infrared communication.
- The full-speed USB device interface conforms to USB Specification Version 2.0 and only needs crystal and external capacitance.
- Emulate a standard serial interface, which can be used to upgrade the former peripheral device or add an excess serial interface through USB.
- Compatible with serial application programs in computer endpoint Windows operating systems.
- The hardware’s entire duplex serial interface sets a transceiver buffer and supports communication, and the baud rate varies
- from 50bps to 2Mbps.
- It supports standard MODEM liaison signals such as RTS, DTR, DCD, RI, DSR, and CTS.
- Add level converter equipment to supply RS232, RS485, RS422, and another interface.
- It supports the IrDA criterion SIR infrared communication and supports the baud rate, which varies from 2400bps to 115200bps.
- It is converted through USB to a serial interface, only compatible with the application layer, not totally.
- The software was compatible with CH341, using the CH341 drive directly.
- Supply the SSOP-20 package without a lead, which is compatible with RoHS.
PC2102 Variant:
The CP2102 is a highly integrated USB-to-UART Bridge Controller that provides a simple solution for updating RS-232 designs to USB using a minimum of components and PCB space. It includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package.
No other external USB components are required. The on-chip EEPROM may be used to customize the USB Vendor ID, Product ID, Product Description String, Power Descriptor, Device Release Number, and Device Serial Number as desired for OEM applications. The EEPROM is programmed onboard via the USB, allowing the programming step to be easily integrated into the product manufacturing and testing.

Shipping Policy
To minimize or avoid tariffs, we ship from the country where the product is made, such as China, Italy, or Taiwan. We sell worldwide in USD.
Fast Delivery! We ship via FedEx, UPS, DHL, and USPS because they're fast, reliable, and easy to track. We process orders within 24 hours, and delivery may take 4-7 working days, depending on your location. We'll email you the tracking number once your order is shipped. We sell in USD.
Shipping Costs: For some industrial products, such as heavy wheels and CNC machines, we calculate shipping costs 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.
Please check your SPAM folder! To provide you with delivery information, we will add your email address to the shipping website so you are notified of delivery until your parcel reaches your shipping address. Please always check your spam folder to ensure our emails from ozrobotics.com and email notifications from DHL, UPS, FedEx, USPS, or other couriers don't land there.
