[CNX-Software] - LimeSDR Mini 2.0 USB SDR board gets an upgrade to Lattice Semi ECP5 FPGA (Crowdfunding)

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. Since it has been used in various projects including digital TV transmitters. 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. LimeSDR Mini 2 specifications: FPGA –  Lattice Semi ECP5 (LFE5U-45F) with 44K logic gates, 108 sysMEM blocks (18kb), 1,944 Kb embedded memory, 351 Kb distributed RAM bits Storage –  4 MB flash memory for data; 2x128KB EEPROM for RF transceiver MCU firmware and data RF Lime Microsystems LMS7002M RF transceiver Tx & Rx SMA connectors Frequency range – 10 [...]
