I received the One board + base board yesterday and it works great! There seems to be one problem however with the power switch on the base board. Given the base board is connected to a battery and the One is not connected to USB, I would expect that I can turn the One on and off with the switch / interrupt it’s power. However, the One stays on whatever I do with the switch.
The On/Off switch works when you don’t use the ENABLE_PIN_IO. In the tracker software we keep the pin HIGH. When you want to turn off the tracker software you should turn the switch to off status and press and hold the reset button for 5 seconds.
