Specifics:

Produces 4 Sounds: Alarm Whistle, Fire Alarm, Ambulance & Machine Gun.
Highly Simple Operation – Schematic Shown.
Small Profile – Excellent for Small Projects.
Volume Control Compatible (through resistor adjustion).
Alternative Module Names: KD9561 CK9561

Description:

This small PCB module allows the user to generate four types of sound (Alarm Whistle, Fire Alarm, Ambulance & Machine Gun). It has a very small footprint making it perfect for projects where space is limited with two screw holes to allow easy and secure mounting. The sound can be adjusted by varying the resistor value (from between 100k and 390K).

Instructions:

Please view the module schematic for more details regarding the appropriate wiring of the module.

Pin Outputs:

Alarm Whistle: SEL1=NC SEL2=NC
Fire Alarm: SEL1=1 SEL2=NC
Ambulance Sound: SEL1=0 SEL2=NC
Machine Gun Sound: SEL1=x SEL2=1
NC:Dangling inputs
1:VCC
0:GND

RRP £2.45
[MA0203] MicroSD TF Card MP3 Player Decoder Board Amplifier Audio Player Module Controller Image

Specifics:

Superior Sound Quality – Onboard 2W mono amplifier (5V power up to 3W) directly connected to the speaker.
Recommended Speaker Specs: 4Ω 3W
Gold plated 3.5mm Audio Jack ports to ensure high quality clear signal output.
The module can be powered through the USB 5V port or MicroUSD port using either a 3.7V lithium battery or mobile phone for example.
Supports MicroSD/TF Card and U disk play mode.
No soldering required – speaker terminals for easy wiring.
Power supply: 3.7 ~ 5.5V
Product size: 45mm x 36mm

Description:

This module will immediately start reading and playing music when powered on. When playing the red LED flashes. This modules supports U disk (tested up to 32GB) and MicroSD Card (tested up to 1B6G) for reading MP3 files. When powered on the module will first read the MicroSD card by default and only switch to U disk reading mode if a card is not inserted. If both storage medias are inserted then you can manually set the play mode using the controls. Buttons on the module will turn the volume up and down, pause or play audio and switch the storage media if both MicroSD & UDisk are inserted at the same time.

Instructions:
Button Key/Operating Instructions:

“Repeat”: changes between either repeat/shuffle play mode.
“Prev / V–“: Press for switching to previous song & long press to turn down the volume.
“Next/v++”: Press for switching to next song & long pressto turn up the volume.
“P / P / Mode”: Press for simple Play & Pause or long press to change the storage source between U disk & TF card mode.

Please Note: In order to long press keep the pressure on the button for at least 2 seconds. Also if you use U disk mode it is recommended to use 5V power supply given some U disk drives do not support a 3.7V power supply.
