1. 40-PIN

The 40-pin header design of ArmSoM products maintains consistency for commonly used interfaces such as I2C, SPI, UART, and PWM. However, due to differences in chip resource allocation, some pins may be vacant or undefined. Developers can refer to the specific 40-pin definitions of each product when using them.

The 5V pin on the ArmSoM 40-pin header does not support input.
