# LimeSDR Mini 2.0 (Lime Microsystems)

> A transmit-capable software-defined radio pairing an FPGA with the LMS7002M transceiver, in a USB stick.

- **Category:** Radio & mesh
- **Availability:** Listed by maker
- **Price:** US$600, checked 2026-09-18
- **Good for:** Experiments that need to transmit as well as receive.
- **You'll need:** A licence for any band you transmit on, and a host computer.
- **Trade-off:** Much more expensive than a receive-only dongle.
