Tipa

Module with integrated microphone for sound recording and reproduction with the possibility of control by buttons or TTL logic levels, eg using Arduino. The total recording capacity is 10 seconds and can be set in the range of 8–20sec by replacing the R4 resistor. Integrated amplifier for speaker connection (8 ohm).


Technical parameters:

- power supply: 3 - 5.5VDC
- control by buttons or TTL levels. eg with Arduino
- recording length 8–20sec, factory set to 10sec
- bandwidth: 1.3kHz / 20sec - 3.4kHz / 8sec
- dimensions: 55 × 38 × 16mm

Control:

- REC button or pin- if the REC button is pressed or the REC pin is high (log.1), the circuit records a sound until the button or log.0 level is released or the memory is full. The red LED lights up in this mode.
- PLAYE button or P-E pin- Press the PLAYE button or short high level on the P-E pin to play the whole message
- PLAYL button or P-L pin- The message will be played only as long as this button is pressed or at a high level on the P-L pin
- switch or pin F-T (Feed-thru) - If a high level is connected or in the ON position, listening via the connected speaker is also connected during recording
- repeat- If the switch is in the ON position, the message will be played repeatedly

The product is not a stand-alone unit, it requires professional installation.
