The M5Stack Fan Module v1.1 is a cooling module designed for M5Stack stacked systems such as the Core S3, featuring a built-in STM32 microcontroller. The module uses the I2C protocol for control, supporting fan speed reading and control, as well as stall protection. This module is primarily used for cooling in stacked systems, effectively improving the thermal performance of the system. The air intake of Module Fan v1.1 is located at the bottom of the module. For optimal cooling performance, it is recommended to stack it on top of the module that requires cooling.
