Kurodako
An eight-channel compact microphone array based on the Beaglebone Black and PDM microphones.
Bill of Materials
- 8x SPM1437HM4H-B PDM MEMS Microphones (Mouser 721-SPM1437HM4H-B)
- 8x 100nF capacitors, 0805 package
- 2x pin headers 2x40, 2.54mm spaced
Possibly also: * 4x 100 ohms resistors
If we want to use wires rather than only PCB microphones: * 8x Micromatch Male-On-Wire 4 pin connector * 8x Micromatch Female-One-Board 4 pin connector SMD * flat cable, 1.27mm, 4 wires
Dependencies
- The PRU code doing the low pass filtering repo [Work in progress]
