NUT4NT+
Four-Channel Multi-Band GNSS SDR with FPGA
With two NT1065 RF-to-Bits ICs the NUT4NT+ board is suitable for antenna diversity GNSS SDR applications. With Lattice ECP5 FPGA onboard the NUT4NT+ is in same time a low-cost and low-power device. All other features inherited from our legacy NUT4NT and new NUT2NT+ design. Two outstanding features are onboard IMU and 24-bits DAC for fine TCXO frequency control.
