Description
Another tiny but powerful board that is perfect to get sound and movement to your prop. Will rotate through sounds files so you can multiple sounds for one prop. Pair it with a relay and it will activate the relay while the MP3 file is playing. Runs on only 5V so you can use any phone charging brick with at least 2A. This board packs a lot into a tiny space. It has a built in PIR (Motion) sensor to detect movement. It has 4MB of on-board memory to hold your sounds or use the SD Card slot to hold larger files. It has outputs pins to power a speaker up to 3 Watts and has an on-card button to control the volume or use the 3.5mm audio jack to take your sounds out to powered computers speakers to get some real loud scary sound. It has a pin hole for a busy indicator that can control a relay to get your prop moving. It has a Micro USB connector so you can use the included USB cable to transfer file directly to the board or power the board with an external 5V source through the power pins. Power and speaker out are JST connectors and will be shipped with the leads for the JST connectors.
We offer this with the 5V Busy/Trigger wire. This board should be paired with a Heavy Duty relay which successfully drive our LED lit eyes.
The board can also be ordered as a complete mega kit with a heavy duty relay pre-wired to the “busy” wire
Be sure to watch the video on The Makers Cave YouTube channel to see this board in use and how it’s wired up with a relay: All In One MP3 PIR Relay Prop Controller
Comes with JST connectors for both the external 5V power source and the external speaker that uses the board’s 3W audio amplifier.
Features
1. Adopts a PIR motion sensor that can detect max. 3.5 meters distance.
2. When it detects a moving human body, the device automatically plays back a sound message.
3. Built-in 4MBytes flash memory and supports max. 32GB micro SD card as well.
4. Supports to store multiple audio files on the memory, and if there are multiple audio files it plays next track in order after each activation from the PIR.
5. Load audio files onto the flash memory through the micro USB port, which is connected with a computer.
6. The on-board flash memory or micro SD card works as a USB flash drive on computer.
7. Built-in 3 watts class D mono audio amplifier, and able to directly drive a 1-3 watts (4-8 ohms) speaker.
8. Adjustable 6-level volume through pressing the volume button repeatedly.
9. Equipped with a 3.5mm audio jack that is able to be connected with an external amplifier or active speaker.
10. Busy signal output available that is able to work with a relay to control other external equipment like LED light,motor, etc.
11. Design with low power consumption and suitable to supply power using a 3.7V rechargeable lithium battery or 3 x AA / 3 x AAA alkaline batteries.
12. Supports to supply power directly through the micro USB port as well using an phone charger (5V 1A power adapter).
13. Equipped with charging circuits and it is possible to charge the attached lithium battery through the micro USB port.
