==Peripheral ADC ==
A SPI bus is a synchronous serial communication interface used in embedded systems. It is typically used to perform short-distance communications between microcontrollers and peripheral devices.
The ADC module available on AURA is based on i.MX93 SoC. The SOC has one instance of the ADC module: it is an 8-channel 12-bit 1MS/s ADC with 4 channels connected to pins in the package. It has its own dedicated pads and is not muxed with GPIO.
