Hi, just been looking at the Daisy Seed schematics. Am I right in thinking the Seed can be completely powered by the USB, or is it advisable to use a separate Vin? Is there any problem having both plugged in, or will the regulators take care of this?
I can see there that onboard the Seed there is a TPS6217 step down converter generating +3.3V_D which powers the RAM, flash memory and is used for the Reset/Boot Flash switches, and a LP2985 linear regulator for +3.3V_A used for the codec and ADC reference. What is supplying the +3.3V for the STM32 VDD?
Thanks in advance!
