4-Mic Voice Development Kit
Evaluation and development of XVF3800 solutions can be done using the XMOS XK-VOICE-SQ66 4-mic Voice Development Kit. A set of pre-built firmware binaries for this kit are available which allow designers to quickly get started with the solution.
A standard 40pin connector compatible with a Raspberry Pi supports evaluation and integration with host applications.
Kit Features
- an xcore.ai processor
- QSPI flash memory
- a DAC for audio output
- a USB interface and 6 PDM microphones.
These microphones can be configured as either a 100 mm linear or a 66mm square 4 mic array to match target form factors. - An extension connector can be fitted that allows a user to connect their own custom microphone array to the device.
- Firmware loading and debug access is provided via an XMOS standard XSYS2 connector which supports the XTAG4 debug adapter.
- The board can operate stand alone and has a 40 pin HAT complaint connector and form factor which allows it to be mounted on top of a Raspberry Pi host.
- Kit comprises both the XK-VOICE-SQ66 processor board and a separate XTAG-4 debug adapter
