Grove - MP3 v2.0
Grove-compatible MP3 audio playback module controlled via UART, for embedded sound effect and music playback projects.
Pinout
- 5VGrove connector red wire
Grove UART connector power input. Seeed wiki direct wiring table maps Seeeduino 5V to the Grove-MP3 v2.0 red wire.
Type · PowerVoltage · 5V - GNDGrove connector black wire
Ground reference. Seeed wiki direct wiring table maps Seeeduino GND to the Grove-MP3 v2.0 black wire.
Type · GroundVoltage · 0V - RXGrove connector white wire
UART receive line for the Grove-MP3 module serial command interface. Seeed wiki describes the module as using a Grove UART interface and maps the white wire to host D3 in the direct wiring table.
Type · UART - TXGrove connector yellow wire
UART transmit line for the Grove-MP3 module serial command interface. Seeed wiki describes the module as using a Grove UART interface and maps the yellow wire to host D2 in the direct wiring table.
