Addressing Case Incompatibility with Lime SDR Mini 2.0

by vileer d

Many of you should have received your LimeSDR Mini 2.0 by now, as some time has passed since shipping started. Unfortunately, you may have noticed that due to hardware changes, the current Lime AC Case is not compatible with the Mini 2.0. However, with a little modification, you can make the Lime AC Case v1.1 work with the LimeSDR Mini 2.0, which we will discuss in a moment.

First, we have received numerous questions about whether we have any plans for a case for the LimeSDR Mini 2.0. The good news is we do plan to design a new enclosure for the Mini 2.0. We are working on the Lime AC Case 2.0, which will be compatible with both the LimeSDR Mini 1.x and 2.0 versions.

The bad news is that we may not start working on the Lime AC Case 2.0 before June. Some of you might have noticed that we’ve pre-launched a project called "Pi-Cast" on Crowd Supply. "Pi-Cast" is a portable IPKVM (short for Keyboard, Video, Mouse over IP) device, that allows remote control of computers over a network without software installation and provides deep access like BIOS modification and OS installation. For more information, visit

Currently, "Pi-Cast" is our top priority. We hope to launch it before June and, after that, we will begin designing the Lime AC Case 2.0. If plans change, the design work for the Lime AC Case 2.0 will be postponed accordingly.

In the meantime, if you want to use the Lime AC Case 1.x with the Mini 2.0, here’s a solution from the community. The method comes from Christopher KB3CS. Follow these detailed steps:

  1. Install the LimeSDR Mini 2.0 in the top case as usual. Then, place the thermal pad on the bottom PCB as shown below.
  1. Flip the bottom case over.
  1. Use some tape to secure the top and bottom covers together. It's worth noting that you can find appropriately sized M1.6 screws to secure the top and bottom shells together for a sturdier mount.

A huge thanks to Christopher KB3CS for providing this solution and the accompanying images.

That’s all for this update. We hope to pre-launch the new enclosure as planned.
