The board is equiped with a AMBE 3000 Vocoder and PCM3500 Codec. DVMEGA AMBE 3000 shield fits on top of an Arduino MEGA.
The PCM3500 converts the analog microphone signal into a digital stream (PCM). Then, the digital PCM stream is converted back into an analog audio signal. The digital PCM format is 8Khz with a depth of 16 bits.
The AMBE3000 Vocoder makes of 128000 bps a digital signal of 3600 bps.
DVMEGA AMBE 3000 can be used as AMBE Dongle (Digital Voice converter) but also as a digital transceiver in combination with the Dual band radio shield or GMSK shield.
- Fits on Arduino MEGA 2560
- Free LF Audio Board as a kit
