Arduino board with 3.3v GPIOs but chip to flash is 1.8v
What's the easiest way to do it without spending much money? I have jumper cables that fit both ends, but not sure what I can put in-between. It's 8 pins on each side.
This has to be done without the computer being powered on.
I saw a 3.3v to 1.8v adaptor that people use with CH341A but it looks like junk. On the other hand, I am not willing to spend a lot of money for something that I should be able to do with my little arduino or an esp32.
Help please! Thank you 😄
