The WAVE-21440 is a High Baud Rate adapter. it supports various IO Levels and comes equipped with a variety of protections (such as overvoltage, anti-surge, anti-static, etc.)

Features

  • Adopts new version CH343G chip. Compared with CH340G, it supports higher data rate (up to 6Mbps) and more serial port IO levels (5V / 3.3V / 2.5V / 1.8V)
  • Supports Mac, Linux, Android, Windows 7/8/8.1/10/11
  • Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock resistance, stable and safe communication performance
  • Onboard IO protection circuits, anti-surge, anti-static, stable and safe communication performance
  • Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level
  • Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly)
  • Adopts double-sided black immersion gold process, which is durable and has a good look
