Brand: u-blox · SKU: UBX-M9140 · MPN: UBX-M9140 · Category: Components
The UBX-M9140 SoC is part of the u-blox M9 standard precision GNSS platform, succeeding the M8 range. It delivers meter-level accuracy and supports concurrent reception of up to four GNSS constellations (GPS, GLONASS, BeiDou, Galileo) with SBAS and QZSS augmentation. It offers high sensitivity (-167 dBm tracking & nav) and fast acquisition times (2s hot/aided start, 24s cold start). The chip provides a position update rate of up to 25 Hz, making it suitable for dynamic applications like UAVs. It includes advanced security features like RF interference, jamming detection, and spoofing detection, with active GNSS in-band filtering to mitigate interference. The SoC features an integrated TCXO oscillator, 8 MBit flash memory (external required for full support), and a DC-DC converter (external required). It interfaces via UART, USB (full speed 12 Mbit/s), DDC (I2C compliant), and SPI. Available in a 40-pin QFN package (5.00 x 5.00 x 0.55 mm), with Professional grade (UBX-M9140-KB) and Auto
