ISD4004 voice module voice recording module development kit
NewWay voice recording module Rec-1000 benefits:
1 onboard a 51, which has been burning the voice recording process , to achieve a key recording function, of course , more complex functions can be for you to realize the full set of data sent to the microcontroller , microcontroller programming and no ordinary 51 any distinction , developers can use it to simply be done directly .
2 leads to two control foot -board microcontroller , you can then external control signal is applied directly to the onboard microcontroller, while both the microcontroller interface or RS232 interface (TTL level ) , you can also send commands to control the onboard serial port on the external SCM , we provide a full range drivers in the data , for your convenience .
3 If you do not want to use the on-board microcontroller friends, we have all the control interface ISD4004/4003 lead voice chip , and made a clear and accurate labeling , allowing you to use other external MCU directly controls the ISD4004/4003.
4 onboard microphone, direct recording .
5 onboard LM386 amplifier system, sufficient to meet the ordinary demands.
6 We designed two speaker interface , allowing you to cascade with different speakers on different occasions .
7 onboard audio input interface, send your recordings with our line , can be achieved from a computer or other audio playback devices direct access , to achieve high -quality recordings.
8 onboard audio output interface, and an external amplifier can be connected directly to the system or headphones , to achieve high -quality playback
9 -board 3V power conversion modules, system cascade convenient and 5V .
10. Onboard MINI-USB interface for take power , so you do not have the power to find that , in front of the computer can be developed .
11 on-board power socket , allowing you to take power in the practical application of convenient , safe and reliable.
12. Onboard two buttons, all connected to the microcontroller, facilitate the development and application .
13 on-board switch, and power indicator , status indicator , facilitate the development and application .
14 onboard volume control knob can be adjusted according to the output volume .
15 and we will send you the module schematics , MSP430 program, 51 program that allows you to quickly grasp of programming and development ISD series chips.
