I need to have a first prototype of an wide band ultrasound recorder (1 - 200 Khz) based on an pdm microphone. The device must be able to record 1 channels in wav files on sdch or sdxc card. I hope a ultralow power consumption device, which can make schedulded records and triggered records. Please Contact me for further informations.
