I2c Level Shifter. Detailed technical information about the level shifter board can be found in the user manual. I successfully used one on a pi1541 drive emulator for a commodore 64.
It is not intended for hs mode systems which may have a bridge with a level shifting possibility. I successfully used one on a pi1541 drive emulator for a commodore 64. This breakout has 4 bss138 fets with 10k pullups.
This is called logic level shifting.
The level shifter board provides voltage level translation from 1 2v to 3 3v for the aardvark i2c spi host adapter the beagle i2c spi protocol analyzer and the cheetah spi host adapter. One consideration that must be taken into account if this level shifter is used for i2c which requires pullup resisters for the bus. Bi directional level shifter circuit connects two different voltage sections of an i2c bus system. This level shifter board combines the ease of use of the bi directional txb0108 with an i2c compatible fet design following nxp s app note.
