KAmodRPi-Pmod-HAT

Description

KAmodRPi-Pmod-HAT is a HAT for Raspberry Pi 4B/3B+/3B/2B/B+ minicomputers that allows use of the communication interfaces available on the 40-pin minicomputer connector. The overlay provides connectors in the Pmod standard and in the KAMAMI standard for I2C, SPI and UART interfaces.

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.
