If you want smaller PCB footprint, better parameters, or more channels, there are level shifter chips, with many of them wonderfully suited for I2C (read the datasheet!). As we’ve featured ...

the Pi doesn’t have a built-in ADC to read the voltage off the light-dependent resistor that he (presumably) had in his junk box. You can, of course, buy I2C ADC chips and modules, but when you ...

The DB-I2C-S-APB-BRIDGE is an I2C Slave Controller IP Core focused on low VLSI footprint ASIC / ASSP designs not requiring internal configuration & control registers (and thus no local host CPU ...
