Module NEO-6M U-BLOX comes with a USB Micro interface, no longer need to use USB-TTL and other tools.6 module is ideal for battery-operated mobile devices with very strict cost and space constraints. The 51-channel u-blox 6 positioning engine boasts a Time-To-First-Fix (TTFF) of under 1 second. GPS. Set aside a TTL interface, easily use the USB-TTL or external MCU control to receive. The dedicated acquisition engine, with 2 million correlators, is capable of massive parallel time/frequency space searches, enabling it to find satellites instantly. Innovative design and technology suppresses jamming sources and mitigates multipath effects, giving NEO-6M GPS receivers excellent navigation performance even in the most challenging environments.
