Lime Microsystems is preparing to launch the new LimeSDR Mini 2.0 which is a successor to the popular LimeSDR Mini board and retains the same LMS7002M at its heart but moves from the Intel MAX 10 FPGA to a Lattice Semiconductor ECP5, dramatically increasing the number of programmable logic gates on-board from 16k to 44k, more even than the LimeSDR USB.

This new board unlocks the potential for running a range of workloads directly on-device by customizing the open-source gateware made available to all users. Whether it’s adding signal detection capabilities, noise-reduction processing, or filtering, the extra capacity in the FPGA provides room for experimentation.

Moreover, the specifications of this board remain the same, matching feature-for-feature the radio functionality of the original LimeSDR Mini, including its support for operation between 10 MHz and 3.5 GHz, full-duplex reception and transmission, 40 MHz of radio-frequency bandwidth, and a USB 3.0 interface to a host device.
