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 WebJan 29, 2024 · This would not have been a problem but both the shikra and bus pirate are rated for 3.3v chips. I considered creating a voltage divider to step the voltage down but after a little Googling, I came across the CH341a with the 1.8v adapter. I decided to order it with one-day shipping.

WebFeb 14, 2024 · The SX1278 is a 3.3V MAX device and needs SPI to set it up, plus other connections. The 18LF2520 will work on 3.3V or 5.V. The PICKIT3 uses 5V (5V suggested in the set-up) to program the PIC. From tests, I've found that a 5V LCD will power from 5V and work with 3.3V DATA. When wiring the circuit (using fuse wire) I connected the … 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. phone is blank
