I purchased a few Seeeduino Stalker V3’s and have several question about voltages so I don’t damage anything. I have read the Wiki, but still not sure.
I am not using the LIPO battery and not using the solar cell. I am connecting it via the UartSBee V4.
I have the UartSBee V4 set for 5V.
QUESTION 1: does the Stalker automatically drop the voltage to 3.3V for the onboard Bee plug in?
QUESTION 2: are the analog and digital Arduino pins (D0-D13 and A0-A5) working at 3.3V or 5V?
QUESTION 3: are the I2C and ICSP connectors running at 3.3V or 5V?
QUESTION 4: Will the VCC connection on the board be 3.3V or 5V?
QUESTION 5: after I program the board and don’t need the UartSBee V4, what are the different ways that I can power the Stalker? Can I power it through the solar connector and if so, what voltage(s) are safe? Can I power it through the VCC connection, and if so, what voltage?
