LORDWORLD

LORDWORLD 8CH USB to TTL UART Converter development board

SKU CH-41N0-44VPY

Eight-channel USB-to-UART converter with hardware flow control, per-channel 3.3V/5V level selection, TVS surge suppression and self-recovery fuse protection in a CNC-machined aluminium enclosure

  • Eight independent UART channels with hardware flow control for concurrent communication
  • Self-recovery fuse and protection diodes deliver stable current and voltage with over-current and over-voltage safeguards
  • Onboard TVS suppresses surge and transient spike voltages for lightning and ESD protection
  • Selectable 3.3V or 5V TTL logic levels via onboard switch
  • CNC-machined aluminium alloy enclosure with four status LEDs for power and transceiver indication

Eight-channel USB-to-UART converter

The LORDWORLD board expands a single USB port into eight independent TTL serial channels with hardware flow control. Each channel operates concurrently, making it suited for developers who need to debug or control multiple UART devices at once. The aluminium enclosure and CNC finish provide a rugged housing for bench or field use.

3.3 V and 5 V selectable logic levels

A built-in voltage translator lets you switch each serial port between 3.3 V and 5 V TTL levels to match target hardware. Self-recovery fuses, protection diodes and onboard TVS devices guard against over-current, over-voltage, surge and ESD events. Four status LEDs show power and transceiver activity for quick diagnostics.

USB interface limits concurrent bandwidth

The single USB connection shares total throughput across all eight channels, so very high simultaneous data rates on every port will hit the host bus ceiling. Very long cables or electrically noisy environments may still require additional isolation beyond the onboard suppression. Buyers needing galvanic isolation or more than eight ports should look elsewhere.

Questions about this item

Will the 8-channel UART converter work alongside my legacy 3.3 V serial devices?

Yes, each channel has an onboard voltage translator and a 3.3 V / 5 V level switch so you can match older 3.3 V logic without extra circuitry.

How can I confirm every channel is communicating after I plug it in?

Four front-panel LEDs show power and per-channel transmit/receive activity, letting you verify traffic on all eight UART lines at a glance.

Does the aluminium enclosure ship with cables or must I source DB9 / header leads separately?

The unit includes the protected converter in its CNC-machined aluminium case; DB9 cables or pin-header leads for the eight TTL ports are not supplied.
