BCD
When this jumper is shorted in position UEXT – the board is power suppied via
UEXT. When this jumper is shorted in position BAT – the board is power supplied via
BATTERY, USB or external power supply.
Default state is shorted in position BAT.
When this jumper is closed, codec is able to boot firmware from EEPROM. This is for
standalone mode.
Default state is closed.
This jumper connects SPI2_MOSI signal with SPI1_SCK signal.
Default state is closed.
This jumper connects SPI1_SCK signal with DREQ signal.
Default state is closed.
When these jumpers are shorted in position MP3_RST and DREQ, the codec is
controlled direct via UEXT, without involving STM32F103RBT6
are shorted in position TXD and RXD - via the UART interface of UEXT may be
submitted to STM32F103RBT6 commands to operate the codec.
Default states are shorted in positions MP3_RST and DREQ.
When this jumper is closed, STM32F103RBT6 must not control the VS1053 RESET,
because VLS_RST jumper connects VS1053 pin 3 (XRESET) to ground
Default state is opened.
When this jumper is closed, STM32F103RBT6 is in reset.
Default state is closed.
This jumper connects RST signal with TRST signal.
Default state is opened.
This jumper connects the battery charger input and output. When is closed the battery
charger is disabled.
Default state is opened.

(PD0/OSC_IN) and pin 6 (PD1/OSC_OUT).
Quartz crystal Q1 (12.288 MHz) is connected to VS1053 pin 17 (XTALO)
Quartz crystal Q2 (8 MHz) is connected to STM32F103RBT6 pin 5
