  • NOTE: SPI not supported. The datasheet T5400.pdf says: “I2C and SPI interface”, but the comment of the code in the Github (Design Files) says: “NOTE: SPI is currently unsupported in the hardware.” I would find it helpful if the product description page were annotated when you are aware that the datasheet is wrong.

    NOTE: Only one T5403 per I2C bus, since the slave address is fixed at 0x77.

No public wish lists :(
