I2C24IO PMOD Demo
This project is a 24-bit digital IO expander module, using the Texas Instruments TCA6424A circuit utilizing I2C. The design is available with a Type-6 or Type-6A compatible I2C PMOD compatible connector interface per open PMOD interface standard v1.3.1 by Digilent Inc. PMOD (peripheral module interface) standardizes connectivity with FPGA or microcontroller development boards.
