- 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
