SKU CH-PW94-YKP0F

A stereo amplifier board delivering up to 50W per channel into 4Ω speakers with Bluetooth, AUX and USB-C inputs and multiple protection circuits

  • Product typePro Audio - Audio Mixers
  • Wireless streaming up to 15 m range
  • Three input options: wireless, AUX and USB-C
  • 50 W per channel into 4 Ω speakers
  • LC-filtered output for clean, low-noise sound

Amplifier Board with Multiple Inputs

The eBags DROK TPA3116D2 board is a stereo amplifier that delivers 50W per channel into 4 ohm loads when supplied with 21V. It accepts power from 5V to 27V, with 8V to 24V recommended, and includes LC-filtered outputs for clean audio. Protection circuits cover short circuit, over-voltage, under-voltage, over-temperature and reverse polarity.

DIY Builders Needing Wireless and Wired Flexibility

This module suits hobbyists building custom speaker systems who want Bluetooth, AUX and USB-C inputs on a single compact board. The rotary encoder handles volume, play, pause and track control. Buyers who require balanced line inputs, multi-channel surround decoding or rack-mount hardware should look at other solutions.

50W-per-Channel Output at 21V into 4 Ohms

The key specification is the rated output of 50W per channel when powered at 21V driving 4 ohm speakers. Lower supply voltages reduce maximum power: 40W at 18V, 30W at 22V into 8 ohms, and 20W at 12V into 4 ohms. Match your power supply and speaker impedance to the desired output level.
