The OMAP-L138 SOM-M1 included in the EVM has additional power measurement circuitry added to the PCB to assist in development efforts; this SOM is identified as model number SOMXOMAPL138-11-1602AHCR and is only available as part of the EVM.

The OMAP-L138 SOM-M1 with the same memory configuration that is available in production quantities from Logic Distributors does not contain this power measurement circuitry; this SOM is identified as model number SOMXOMAPL138-10-1602AHCR.
