Raspberry Pi Compute Module 4 IO Board _RPI_Christmas Ensure you connect the ground

Ensure you connect the ground from the 5V power supply to your microcontroller ground

to provide some filtering on the power supply

Check out this project

Extremely fast and very low propagation delay Flip-Flops are added on I2s signals output from FPGA

txt The easiest way to do that is to insert the programmed Pi SD card into your computer and look for the config

Raspberry Pi Compute Module 4 IO Board _RPI_Christmas Ensure you connect the groundExposing every interface from Raspberry Pi Compute Module 4 (not included), the Compute Module 4 IO Board provides a development platform and reference base board design for the most powerful Compute Module yet! Compute Module 4 is not included. Specifications External power connector (+12V, +5V) As per the datasheet, power needs can vary but 9W it is recommended to budget for 9W, so a 2A 12V PSU will be fine for most users, or grab a 5A power supply
