Dayton Audio KAB-100Mv2 1x100W Class D Audio Amplifier Board with Bluetooth 5.0

Tip:  Take a look at the table in this blogpost to see which power supply to choose for this product.

The Dayton Audio KAB-100M Bluetooth Amplifier Board delivers high quality sound without drawing a lot power. This is due to the highly efficient Texas Instruments TPA3116 Class D amplifier chip. The TI TPA3116 operates at 90% efficiency. The added heat sink mitigates any issues that may arise from excess heat. 

Unlike other amplifier boards, the Dayton Audio KAB-100Mv2 includes a built-in Qualcomm Bluetooth 5.0 module with aptX HD. The advantage of Bluetooth 5.0 is its low power consumption which prolongs the playtime of battery powered builds. The streaming audio quality rivals that of CDs since the Bluetooth chip supports aptX, aptX HD, aptX LL, SBC & AAC. High receive sensitivity with RF power up to 9 dBm and -90 dBm, and on board antenna insure stable wireless connectivity up to 15m (50ft.) On board external antenna jack enables the KAB board to be mounted in a metal enclosure with an external antenna (sold separately). Designed and built for Bluetooth demonstration purposes, this fully functioning module provides a turn-key approach to Bluetooth certification for consumer goods. If the application of this board is for the hobbyist or industrial purposes then nothing is required to enjoy the full convenience of pairing and streaming high quality Bluetooth audio. The KAB-100Mv2 is also CE and FCC ready for certification purposes.

Included with the KAB-100Mv2 are two wire harnesses: one for DC power and the other for connecting to stereo speakers. For many users, these cables are all that is needed to complete a project. Since they have Molex Mini Fit Jr connectors to speed-up installation and create confident a connection, there is no need to solder or troubleshoot loose and unstable contacts.

The Dayton Audio KAB-100Mv2 will remain powered up to 7 days in standby mode even while Bluetooth is enabled. This standby time is approximately 4x longer than the competition due to the use of a high efficiency DC/DC converter which minimizes power consumption thanks to the employment of a micro controller as the PMU (Power Management Unit).

The Dayton Audio KAB100Mv2 features numerous power options for creative, wireless sound projects. This flexibility eliminates limitations often caused by most other amp boards. Therefore, your design can be cord restricted or truly portable.

For portable applications, there is an optional function cable kit (KAB-FC) which permits the connection of rechargeable batteries to power the board. NiMH, lead acid, or NiCad batteries will recharge straight from the board using a 15~24 VDC, 1A power supply. Use extreme caution because the Bluetooth amp board does not provide under/over charge protection and the connected power adapter cannot have an output greater than 30 watts.

Solar charging is also an option; this application requires solar batteries with float (open) voltage with 16.5 to 21.5 VDC, and 20 to 100 watt panel.

Eight AA alkaline batteries can also power this board, but do not connect the recharging feature for this type of use.

The best rechargeable battery option makes use a separate interconnect board from Dayton Audio (KAB-BE) which holds three 18650 Li-Ion batteries. This portable power source is highly recommended since this add-on battery holder board does provide under/over voltage protection. A 19 VDC, 1-5A power supply is your best choice for charging the expansion board. (15 VDC Min required and 24 VDC Max)
