3.3V Supply Requirements

The MitySOM-335x SoM is powered by an external 3.3 Volt to 5.0 Volt power supply. This power supply is used to derive additional voltages on the module. Actual power utilization of these modules is highly dependent on the application and factors such as:

  • CPU clock rates
  • Peripherals powered up or down
  • Utilization of CPU
  • Graphical Usage

The supply information provided is the maximum possible given the on-board power supply design on the module. This information is provided for designers sizing an external power supply. In the majority of applications the module will draw far less than the design maximums provided here.

Supply (V) Max Current (mA) Max Power (mW)
3.3 TBD TBD

Measured 3.3V power draw for various uses

This section attempts to give you a better feel for module power draw under various configurations. The power consumption here includes the entire module, not just the AM335x. It includes the on-board DC to DC converters, power good LED status, the AM335x, the NAND FLASH, SPI FLASH, and miscellaneous crystals, etc.

These numbers are preliminary.
