Compute Module 4S

Based on the Raspberry Pi 4 Model B architecture, Compute Module 4S is intended for specific industrial customers migrating from Compute Module 3 or Compute Module 3+ and is not for general sale. For new customers who are designing products, we recommend using Raspberry Pi Compute Module 4.
