UUGear’s VUÂ GPSDR is a low-cost GPS-disciplined SDR expansion board designed specifically for the Vivid Unit, a palm-sized Rockchip RK3399-based touchscreen SBC we covered back in 2024. The VU GPSDR is built around the RTL2832U ADC and Rafael Micro R860 tuner, but what makes it different from SDRs like the PhaseLatch Mini and DeepRad SDR Â is the integration of a u-blox NEO-M8N GPS module. This module provides a GPS-disciplined 24 MHz clock reference to the Si5351 local oscillator, which ensures high frequency stability and timing accuracy that is typically only found in much more expensive SDR hardware. VU GPSDR specifications: Supported Platform â UUGear Vivid Unit via Vivid Unit Extender Gen 1/2 (See details below) MCU â STM8S003F for board-level controls RF Tuner â Rafael Micro R860 ADC â Realtek RTL2832U Frequency Range â 500 kHz to 1.766 GHz Bandwidth â Up to 3.2 MHz (2.4 MHz recommended for stability) HF […]
