Measurement Jumpers
To facilitate the measurement of run, charge, and quiescent currents, two measurement jumpers are included.
These are normally closed jumpers combined with a 2-pin 0.1” footprint. To take a measurement, cut the jumper
and install a 2-pin header and use banana to IC hook cables to a DMM.
LiPo and Charging
The RTK Surveyor houses a standard 1000mAh 3.7V LiPo. The charge circuit is set to 1A so with an appropriate
power source, charging an empty battery should take roughly one hour. USB C on the RTK Surveyor is configured
for 2A draw so if the user attaches to a USB 3.0 port, the charge circuit should operate near the 1A max. If a user
attaches to a USB 2.0 port, the charge circuit will operate at 500mA.
