I’ve got another wiring diagram for yet another spin on this project. This version uses a different Bluetooth received with a volume control switch so you don’t have to rely on your Bluetooth device to set your volume. Since that Bluetooth receiver doesn’t have a built in amplifier you can then add one like this after the receiver to get the nicer controls with amplification needed to drive the speakers.
Bill of Materials
- [ CE08483 ] Enclosed Speaker - 8 Ohm, 5 Watt
- [ DFR0719 ] Bluetooth - 5.0 Audio Receiver Board-Controllable Volume
- [ CE09453 ] Adjustable Dual Channel Audio Amplifier
- [ DFR1026 ] DC-DC Charge Discharge Integrated Module (5V/2A)
- [ CE09094 ] 18650 Battery Holder (Through Hole tabs)
- [ CE04624 ] Polymer Lithium Ion Battery (LiPo) 18650 Cell (3.7V 2600mAh)
Update
If DFR0719 is out of stock, there is a new version that has an integrated amp and screw terminals which should simplify the overall project!
