// This sketch program ESP32 by flashing bin file from SD Card
// Hardware wiring:
// - Brain GPIO28 <-> ESP32 IO0
// - Brain Reset <-> ESP32 Enable
// - Brain TX/RX <-> ESP32 RX/TX
// This sketch program ESP32 by flashing bin file via Serial Host.
// Hardware wiring is a bit different between S2/S3 and ESP32 + USB-to-UART chip
// For S2/S3 with native USB
// - Brain GPIO28 <-> ESP32 IO0
// - Brain Reset <-> ESP32 Enable
// - Brain USB Host <-> ESP32 native usb
// For ESP32 with USB-to-UART chip
// - Brain USB Host <-> ESP32 native usb
// - There is no need to connect IO0/Reset since we will use DTR/RTS to reset ESP32
// required for Host MSC block device
