Dear
I’m a newbie.
I would like to know if it’s possible to use 3.6v (LS33600 http://www.saftbatteries.com/force_download/LS33600.pdf) by Barrel Jack with:
SparkFun XBee Shield : https://www.sparkfun.com/products/12847
Or better, use the JST to power the Teensy (by cutting the VIN/VUSB jumper on the bottom of the Teensy): in this case only 3.3v must be used, what is the tolerance ? 3.6 is to hight ? Must I use schottky diode ?
Best regards.
Philippe.
