This kit is the replacement for K146, our previous 40 second voice recorder module. This kit used the now obsolete ISD2540 chip. K188 uses the ISD1740 chip. It has much the same specifications as the previous chip but with some extra features that make it easier to use.
The ISD1700 series of chips offer a wide range of message durations, ranging from 30 seconds up to 240 seconds depending on the chip. The sampling frequency of each chip can also be adjusted from 4 kHz to 12 kHz with an external resistor, giving greater flexibility in duration versus recording quality.
Recordings are stored in on-chip Flash memory, providing non-volatile storage when power is removed. The audio data is stored directly without digital compression, which provides better quality voice and music reproduction.
These chips are designed for operation in either standalone or microcontroller (SPI) mode. This kit provides interfaces for both
