I have a few questions regarding the power section.
Where can I find a detailed description for the Meadows Board pinout, in particular AREF, BATTERY, ENABLE, RST?
Is there any schematic detailing how the power section works?
Is there a power switch/mux between the USB and the lithium battery?
What is the max load on the 3.3V and 5V power out pins?
I going to take a shot at this and maybe someone else can chime in on this.
EN - Enable pin. This pin is responsible for turning off the device by pulling it to a logic low.
RST - Reset. Recycle the device power, similar to reboot you computer.
AREF - This pin is a voltage reference pin I believe. Meaning, it is close USB voltage if USB is plugged in or battery voltage if running on lipo. If both are connected, then the highest voltage is reflected.
BATT - the battery voltage, this is post charging. Typically, should be around 3.3v. Can also power the device from a 3.3v supply.
Hello,
In the page “Wilderness Labs Developer Portal”, in EN section,
“… as shown in the following schematic:”, i do not see the schematic.
Where can I see it ?
Thanks
