Function

Realize the recording function by  our WTR chip and external SPI FLASH. With good quality sound, long recording  duration and low cost. Currently, the longest recording duration is 2730 seconds  for this module.

WTR-S4 module with key mode, One key  one voice mode (record & play by this same key), and three line serial mode.  The mode can not be change after fixed at first time programming. But the  recording can be erased. You should tell us which mode you  need.
