Chip's 3v
WebNov 6, 2024 · There is a good possibility the 3V battery will make the chip come alive. If all else is working this might just get the thing going. Consider using a milliamp meter between the battery and the chip. If you hit say 10 to 20mA there might be a problem that could damage the bios chip and drain the battery. WebMay 6, 2024 · talking to 3.3V logic from 5V logic (pull up resistor to 3.3V), or 74LVC series gates (3.3V powered) with their 5V tolerant inputs. 74LVC gates go down to 1.8V I think should you even need to talk to a 1.8V chip. Going the other way there are some "high voltage open-collector" gates in the 7400

A significantly higher voltage on the 5volt pin will eventually fry the tiny 3.3volt voltage regulator. Powering the board with 5volt on the 3.3volt pin is a sure way of frying the ESP WiFi module. You should power the module with a 5volt cellphone charger on the USB socket.
WebBut that USB chip is probably connected to the 5V rail. So it likely won't power up. That said, maybe you you don't need the USB in the context where you need to power from 3.3V. Make sure you have good regulation on the 3V line. It needs to be spot on 3.3V with ~500mA in-rush capability. Don't hook it up to a bare LiPo battery, for example. WebFeb 9, 2015 · The regulator should be marked K850 (5.0V) or K833 (3.3V). A 5 volt part has a 16MHz resonator may be marked with "A1" or "A'N". A 3.3 volt part has a 8MHz resonator may be marked with "80'0". As others have indicated, you can apply up to 12V at the RAW pin, and measure the output of the regulator. Share.

WebMar 9, 2015 · If the chip Vcc is 3 volts, and you apply 5 volts to an input pin, the protection diode on that pin will try to pull the 3 volt Vcc towards 5 volts. This may destroy that diode, and/or may cause higher than expected Vcc voltages on other parts of the circuit. – Peter Bennett Mar 8, 2015 at 21:38 Add a comment -1 list of sexual sins according to the bibleWebESD Suppressors / TVS Diodes Ultra Small MicroClamp 3.3V ESD & EOS Protection Semtech UCLAMP3341ZATFT.
