USB must not be plugged in and the board has to be power supplied via external power supply (PWR_JACK or BATTERY). MOD-MP3-X ships in two variants – with and without battery. The battery variant employs a Li-ion 3.7 V, 1200 mAh rechargeable battery and an on-board bat- tery charger.
Dimensions: 60 x 60 mm ( 2.36 x 2.36") ELECTROSTATIC WARNING: The MOD-MP3-X board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

− Internal 32 kHz RC − PLL for CPU clock − Dedicated 32 kHz oscillator for RTC with calibration − Low power − Sleep, Stop and Standby modes − VBAT supply for RTC and backup registers − 2 x 12-bit, 1 μs A/D converters (16-channel) −...
The programmed board power consumption is about 70 mA with all peripherals enabled. RESET CIRCUIT: MOD-MP3-X reset circuit for VS1053 includes RC group - R7 (100kΩ) pull- up and C12 (100nF), jumper MP3_RST, jumper VLS_RST, STM32F103RBT6 pin 43 (PA10/USART1_RX/TIM1_CH3) and VS1053 pin 3 (XRESET).
CLOCK CIRCUIT: Quartz crystal Q1 (12.288 MHz) is connected to VS1053 pin 17 (XTALO) and pin 18 (XTALI). Quartz crystal Q2 (8 MHz) is connected to STM32F103RBT6 pin 5 (PD0/OSC_IN) and pin 6 (PD1/OSC_OUT). JUMPER DESCRIPTION: UEXT/BAT When this jumper is shorted in position UEXT – the board is power suppied via UEXT.

In this mode you can use RXD and TXD signals of UEXT connector to communicate between MOD-MP3-X and your computer. For this purpose, for example, you can use our module MOD-USB-RS232, which creates a virtual COM Port. The COM Port setting are 9600bps 8N1.

3 (PC14/OSC32_IN). Battery level status LED (STAT2) activity: - When powered by the battery the MOD-MP3-X indicated low battery level. If voltage of the battery falls below 3.3V then the STAT2 LED starts to blink. - If an external power source is connected, then battery starts charging. In this case STAT2 LED is constantly lit while battery is charging and turns off when battery is fully charged.
Important note: If you apply power to a host device and then connect the host to the UEXT of MOD- MP3-X it might restart your host. The workaround is to connect the host to the UEXT of MOD-MP3-X and then apply power to the host!
