We are using it in a bulldozer, and sometimes the operator forgets to turn off the device.
This morning, it was completely drained.
Update: next post Just the button…you might mount it somewhere more prominent or in-the-way of leaving for the day (loop keys to it or something). You could also grab a large portable battery bank and have it with usb-c cable to provide backup power in these situations
If you’re asking if it’ll charge twice as fast: no
Both ports are connected to V_USB https://cdn.sparkfun.com/assets/d/a/5/1/b/SparkFun_RTK_Express_-_Schematic.pdf and either will charge the battery.
If you connect both to a power source at once nothing terrible should happen as long as the power sources’ usb voltage is the same…I wouldn’t recommend using 2 different power sources, bc if there is any difference in their voltages, the difference will be turned into heat somewhere in the circuit
Additionally, there is a system setting to enable auto-shut off with no charging:
s for system menu
c for Shutdown if not charging
Sorry, our docs haven’t been updated with this feature but you can set a couple hour run time.
That looks perfect. What is the link with more information how I can access that menu?
I’m assuming it has something to do with some kind of console and USB connection to a PC?
Sorry, should have posted the link to System Menu the first time. Yes, much of the advanced config happens over a serial connection or over Bluetooth.
