NS-T is a plug-and-play precision timing and frequency generation GPS receiver, featuring 6nsec (1-sigma) 1PPS timing accuracy and a second precision programmable frequency time pulse phase-locked to 1PPS. NS-T is functionally equivalent to Venus838LPx-T but in NavSpark form factor. NS-T is not Arduino programmable.

The 2nd image shows what the shipped items include.
The programmable time pulse is derived from 81.84MHz clock, it suffers from jitter due to quantization or granularity of the clock. This time pulse is highly accurate in frequency pulse count, but does not have very low phase noise specification. To have low phase noise, customer must add external circuit such as PLL.
