Description
Combines Bluetooth 3.0 Audio Module with Class-D Amplifier and 4.2V Li-ion Battery Charger for wearable/portable audio projects.
Dimensions specifically designed for Dual 18650 Pack for use in bluetooth stereo headphones or portable speakers.
In theory, you should be able to customize it by directly plugging it into a PC with a USB data cable and customizing it with Silicon Labs iWrap software. If you use the APT-X version you should be able to connect to 2 bluetooth devices simultaneously. This should empower users to customize their bluetooth devices for their own specific needs.
Silicon Labs WT32I-A-AI61-APTX Bluetooth Module.
Customize the WT32i with BlueGiga iWrap terminal software by using an external USB to UART hardware device.
SPI headers are for firmware updates only, unlikely you will ever need to use the SPI headers.
