SPECIFIC PRODUCT SOLUTION
USB to TTL UART serial cables made to your drawing
Drawing-based USB to TTL UART cable assemblies with CH340 or PL2303 chip options and customer-defined wiring, connectors and enclosure.
PRODUCT OVERVIEW
A custom serial interface, not a fixed catalog configuration.
Yuefu Electronic makes custom USB to TTL UART serial cables for equipment communication, debugging and parameter configuration. CH340 and PL2303 chip options can be reviewed against the target device and host system. The photographs show a CH340 cable made by us and its exposed conversion board; the final enclosure and cable construction follow the approved drawing.
Start with the information you already have
With a drawing, include its revision, interfaces, pinout and quantity tiers. With photos or a sample, add interface dimensions, wiring information and required tests. Mark undecided items as open.
APPLICATIONS
CUSTOMIZATION & TECHNICAL SCOPE
These are actual manufacturing sample photographs, not a fixed delivery specification. Chip variant, UART logic level, power connection, cable length, connector, pinout and enclosure are confirmed for each project. A 5V power marking does not by itself specify the TX/RX logic level. TTL UART is not a direct RS-232 or RS-485 interface.
TECHNICAL PARAMETERS
FOR A FASTER QUOTE, PLEASE PROVIDE
- Drawing revision or sample reference
- Preferred chip and host operating system, if specified
- Device connector, pinout, UART logic level and power requirements
- Cable length, routing and enclosure requirements
- Quantity tiers, communication settings and sample/production acceptance tests
FAQ
Can you make both CH340 and PL2303 versions?
Yes. We can review either chip option for a customer project. The exact chip variant, driver and target system must be confirmed; we do not assume one chip family is always more stable.
Does the sample define the enclosure and cable length?
No. The photos demonstrate our cable assembly capability. The enclosure, cable length, device connector and wiring can be defined by the customer drawing and confirmed during review.
What is needed to start an RFQ?
Send a drawing or sample reference, device interface and pinout, host system, quantity tiers and any required communication tests. Mark undecided details as open so they can be resolved before sample approval.
