While code that uses core features of an ESP-S3 module should work perfectly, other ESP32-S3 based boards may have components that connect to different pins or components that are not included on our boards. In most cases simply changing pin assignments in your code or adding the missing components via a breadboard will fix any compatibility issues. Please note that GPIO Pin 47 on the Neuron mPCIe module is assigned to the “blink” LED and it cannot be used for other purposes. Refer to the Neuron schematic in our downloads section to avoid using pins that are reserved or assigned differently between boards. The process of migrating code from other ESP32-S3 based board is generally very straightforward,  but there can be occasional exceptions.
