Migrating to the LM811

How to migrate from the LM820/821/822/823 to the LM811?

The LM811 and LM820/821/822/823 have the same dimensions of 25mm x 12mm x 2mm and the USB interface (pin 2 to pin 5) are in exactly the same position.

When moving to the LM811, consider the following:

  • Pin 1 and Pin 6 have different pin assignments to LM820/821/822/823 .
  • The LM811 has extra pins for a PCM interface. If PCM is not required, this will not affect the design.

Please refer to the datasheets for further information.

LM809, LM006, LM820 & LM821: Linux driver installation

There are three different drivers available for these products. We recommend that you use the ‘in kernel tree’ driver where possible, which essentially makes these products plug & play in most Linux distributions which use a recent version of the Kernel. Read more

Linux WiFi Ad-hoc mode

Ad-hoc, or IBSS mode allows you to create a wireless network without a central access point. This guide demonstrates a simple Ad-hoc network using one of our adapters and some basic tools found in most modern Linux distributions.

  • At the present time, IBSS may suffer from high levels of packet loss due to an issue with the driver.
