- kragen 3y agohow low power have you been able to get the esp32 to sleep, if you don't mind sharing? and the stm32g? i'm sure the l4 is fantastic wrt xtensa, in theory risc-v ought to help them with lowering the power suck (it sure helped the gd32v) but i'm not sure it makes a difference in sleep and of course for milliamps per mips, going to subthreshold switching like ambiq will make a much bigger difference than anything architectural
