Description
ProCiv sleeping mask has no amplifier and 180mAh battery. It's not enough. This is 10X louder and will last for 48 hours when used with a 2500mAh battery.
This is only a schematic, no module available as it's for a personal project and uses the existing ProCiv module plus Adafruit modules.
1. Component List:
- Adafruit 2000mAh Li-ion battery
- Adafruit 259 Charger
- Adafruit TS2012 Amplifier
- Adafruit 40mm 3W 4Ohm speakers
- ProCiv bluetooth sleeping mask & module
