I2C bus lines
The KAmodRPi-Pmod-HAT module is equipped with jumpers that allow the connection of pull-up resistors to the VCC to the I2C bus line. Jumpers allow the independent activation of chin up for SDA and SCL lines.
Write protection of the ID EEPROM memory
The KAmodRPi-Pmod-HAT module is equipped with a jumper that allows write block to EEPROM memory. Write Protect protects against unwanted attempts to write data to memory.
