What is the > difference then between monako-evk and the -ac variant? > The major difference between monaco-evk and monaco-ac-evk boards is that of power grid. monaco-evk requires 4 PMICs (2x PM8650AU + Maxim MAX20018 + TI TPS6594) to support higher power requirements of monaco-AA variant of SoC which supports upto 40 TOPS of NPU - whereas this board "monaco-ac-evk" supports 20 TOPS of NPU and has lesser power requirements hence 2 PMICs suffice the power requirements (2x PM8650AU). > Also, from the naming point of view, it is monako-ac-evk, not the other > way. Ack, will change this to "monaco-ac-evk" in the next version.
