- On-board micro-SD memory card adaptor for storing of audio, voice and music files (up to 512 files).
- Supports 64Mb to 2Gig micro-SD memory cards (FAT format).
- Low-cost module for all embedded Audio-Sound applications.
- Supports 4-bit ADPCM (.ad4) file formats with sampling rates from 6Khz to 36Khz.
- Two operation modes:
- Serial Mode: Supports a 2-Wire (Data, Clock) interface to any micro-controller.
- Key Mode: Supports a simple stand alone operation without a host micro.
- Differential 2 line PWM output for direct speaker connection (8 Ohm/0.5W).
- Dedicated 16-bit DAC/PWM audio output to use with an external amplifier.
- Low power
- Low Power Idle current: 8.0uA
- Operating Voltage: 3.3V (Through an SMD jumper * Note-1),
- Min: 2.7V
- Max: 3.5V
- Dimensions: 20 mm (L) x 18mm (W) x12mm (H)
[!] Note: An SMD jumper (on top side of the pcb between pins 1 and 16) must be bridged by soldering prior to use this module. The jumper selects operating voltage between 3.3V or 5V. The 5V to 3.3V regulator is not installed on these modules. Therefore the only option you can select is 3.3V. Please see image 2/2
