I used to work with your LoRa V1 board. As the power consumption in sleep mode was to high I was unable to work with your devices.
However now I can see that you guys have developed the Wireless Stick Lite with a much better power consumption in the sleep mode.
I want to buy several of this if it really attends my expectation. I would like to know more about the Vbat control, and see the Schematic Diagram to understand how you guys are mesuring the level of the battery.
