So this is the first time I'm attempting to flash a BIOS chip using a Raspberry Pi 3B+.
I have the following items with me, a SOIC-8 clip, a Bi-Directional Logic Level Converter, and a Raspberry Pi 3B+ (plus).
This is the logic level converter I brought: KNACRO 8-Channel 5V/3.3V IIC UART SPI TTL Bi-Directional Logic Level Converter https://www.amazon.com/dp/B071RWFF7C
This is the BIOS chip I'm working with: Winbond 25Q64FW https://www.winbond.com/resource-files/da00-w25q64fwc1.pdf
Before I hook things up and fry the BIOS chip I want to get some questions answered and some things cleared up.
This level converter has a "A" side and a "B" side. What I think I understand at the moment is the "A" side gets the 3.3v pins and the "B" side gets the 1.8V. Does this mean I also have to connect up a 3.3v power supply to VCCA and a 1.8v power supply to the VCCB on this logic level converter board?
Also I see the BIOS chip has a tolerance of "1.65 to 1.95V", couldn't I use a couple of AA or AAA batteries to power this chip?
