Do you want to drive each one with an individual GPIO ?

Or use a driver with a shift register, or an IO Expander?

Tips, Buy me a coffee, or three.. PayPal Venmo (See Profile) Up vote any posts that you find helpful, it shows what's working..

"My project involves developing a modular switching system. To accomplish this, I have created a LabVIEW interface to send commands to my first STM32 board via Ethernet. This STM32 board will then relay these commands to the second STM32 board, which will control the relay matrix. Initially, I plan to work with either an 8x8 or 4x4 relay matrix. I am seeking guidance on how to construct the relay matrix and how to control it using my STM32 board."
