![]() The comparison table above shows how the LimeSDR Mini 2.0 fares against the earlier LimeSDR and LimeSDR Mini boards, as well as competing solutions such as HackRF One, Ettus B200/B210, BladeRF x40, or even the entry-level RTL-SDR USB dongle. The company will make the LimeSDR Mini 2.0 open-source hardware, and release the schematics and PCN layout, manufacturing files (e.g., Gerbers, drill, and part placement files), FPGA gateware, host software, documentation, and toolchain configuration before going to production.īeyond the higher number of logic gates, Lime Microsystems lists two other advantages of ECP5 against the MAX10 FPGA: first, it is more readily available (the main reason why LimeSDR Mini 2.0 was designed), and second, it is supported by plenty of open source tools and has a great community of developers that are gathered around ECP5 boards such as OrangeCrab, Radiona ULX3S, or LUNA. USB – 1x USB 3.0 port via FTDI FT60x controller chip.Power Output (CW): up to 10 dBm depending on the frequency.Sample Rate – 30.72 MSp/s with 12-bit sample depth.Lime Microsystems LMS7002M RF transceiver. ![]() Storage – 4 MB flash memory for data 2x128KB EEPROM for RF transceiver MCU firmware and data.FPGA – Lattice Semi ECP5 (LFE5U-45F) with 44K logic gates, 108 sysMEM blocks (18kb), 1,944 Kb embedded memory, 351 Kb distributed RAM bits.Lime Microsystems is now back on Crowd Supply with the similar-looking LimeSDR Mini 2.0 replacing the MAX 10 FPGA with 16K logic gates with a more powerful and capable Lattice Semiconductor ECP5 FPGA with 44K logic gates while keeping the company’s LMS7002 RF transceiver. Since it has been used in various projects including digital TV transmitters. The LimeSDR Mini is an open-source hardware full-duplex USB SDR board based on Intel Altera Max 10 Altera FGPA that was introduced in 2017 on Crowd Supply and raised close to $2 million US dollars.
