Description
Description
Minimal simple I2C level shifter using BSS138TA mosfets.
GND connections aren't strictly necessary. It's enough to connect 3.3V, 5V, SDA and SCL pins.
Connect 3V3 to any 3V3 pin, 5V to any 5V pin, and the MCU 3.3V SDA and SCL pins to SDA3 and SCL3. Then there will be 5V SDA/SCL signals on SDA5 and SCL5
Not printed yet, but I know it works (using it in another design)
