Thread: VBAT Voltage Range for T3.5

    VBAT Voltage Range for T3.5

    I'm looking for the VBAT input voltage range for the T3.5. Is it 3V maximum as I'm going to connect it to a battery that may be as high as 4.2V fully charged? If it cannot handle more than 3V, I will have to add a regulator. Also what voltage range for Reset pin.

    page 31 of https://www.pjrc.com/teensy/K64P144M120SF5.pdf lists the voltage range as 1.71 to 3.6V, matching the 3.3-2.7 of a lithium coin cell. So yes some form of regulation is going to be needed there.
