The FeatherS3 offers amazing features plus a crazy 7x7 RGB LED matrix, all in the super popular Feather format which offers a huge ecosystem of add-on boards, modules and FeatherWings!
Yup! The first one is for the general operation of the board and the ESP32-S3, PSRAM and Flash.
The second LDO powers the RGB LED Matrix and RGB Status LED as well as the AMB light sensor, and it has programmable EN control tied to IO39 + it’s connected to the deep sleep capabilities of the ESP32-S3, so if the ESP32-S3 goes into deep sleep, the 2nd LDO is automatically shut down for you!.
Both regulators are ultra-low noise and have ultra-low quiescent current, and both support a maximum of 700mA output.
