However, read carefully. This amplifier expects an analog input (eg: the headphone jack from a Raspberry Pi). So you can expect a background hiss if you turn the volume up much below the lowest setting. I plan to experiment with adding a small capacitor between the Vin and Gnd to see if it helps, but a bit of hiss is nice in my application (vintage radio). A couple of tips in case they help someone in the future, as this board did not come with a manual: To run in "Mono" mode, you're going to need to blend your inputs. To do this, you attach a 1k resistor to the right and left channels (the red and black wires of the headphone jack). Then you connect both of the opposite ends of the resistors together, and then wire them to both the L-IN and R-IN terminals (eg: they will receive the exact same signal). If you search online, you will find similar instructions which call for 475 ohm resistors and a 20k resistor bridging the end to GND. This is unnecessarily complicated for a weak input signal such as this one and I can confirm that the simpler solution I presented above works wonderfully. Next, if you have a single (mono) speaker, you can connect it in one of two ways. If it's low power (say under 50W or so), then connect it to either R+/R- or L+/L- (doesn't matter which if you blended the signals per above). But if you have a larger speaker (mine is 150W), then you can bridge it by connecting it to L- and R+. This gives you double the power, which is nice, although the hiss might prevent you from taking advantage of it. It is safe to experiment if you have a higher wattage speaker (less power is ok, too much power is not). The amp has a really warm tone, very similar to a record player. Quite a nice sound. Review: Great!! Check solder joints!! - There were a few components that hadnt taken up much solder in the manufacturing process. So just double check all joints before I stalling this. Other than that, this chip puts out a lot of power!! Make sure you use the highest voltage power supply it allows for. Your sound quality will improve alot! ## Features - The power amplifier board is made of high performance Original chip TDA3116D2, 2 channel stereo amplifier, 2x50W output power; - This digital amplifier is made of Use high-performance inductors and high-performance capacitors. - The digital amplifier board is operated by wide working voltage DC4.5-26V(24V recommended)with reverse connection protection,and it is highly recommended for 4-8 ohm speakers; - The TPA3116D2 device features short-circuit and thermal protection as well as over-voltage, under-voltage and DC protection to prevent complete failure. - TDA3116D2 is widely used in store solicitation, home theater, square speakers, etc.due to its excellent performance and comprehensive cost performance. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08GYQTTXF | | Best Sellers Rank | #31,192 in Electronics ( See Top 100 in Electronics ) #163 in Audio Component Amplifiers | | Brand | Beffkkip | | Brand Name | Beffkkip | | Customer Reviews | 4.3 out of 5 stars 162 Reviews | | Included Components | Quick Start Guide | | Item Highlight | Dual-channel digital amp modules for 5-24V DIY speakers, home audio and compact electronic amplification projects. | | Manufacturer | Deegoo-FPV | | Material Type | Printed Circuit Board (PCB) | | Maximum Output Power | 50 watts | | Maximum Supply Voltage | 26 volts_of_direct_current | | Minimum Supply Voltage | 4.5 volts_of_direct_current | | Model | TPA3116D2 | | Mounting Type | Surface Mount | | Number of Channels | 2 | | Number of Items | 2 | | Output Power | 50 watts | | Package Type Name | antistatic bag | | Part Number | Digital Amplifier Board TPA3116D2 | | Specification Met | FCC | | UPC | 789615751414 | | Unit Count | 2 Count | | Voltage | 4.5 volts_of_direct_current | | Warranty Description | 12 months | ## Product Details - **Manufacturer:** Deegoo-FPV - **Maximum Supply Voltage:** 26 volts_of_direct_current - **Minimum Supply Voltage:** 4.5 volts_of_direct_current - **Mounting Type:** Surface Mount - **Voltage:** 4.5 volts_of_direct_current ## Images ![TPA3116D2 Stereo Amplifier Boards, 2-Pack, 2 x 50W - Image 1](https://m.media-amazon.com/images/I/71hvknc-t1L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little board but read carefully! *by I***D on March 18, 2025* Super fast delivery and a nice board (with a spare).

I mounted some speakers, got a dollar store plastic case and mounted this little amplifier inside, plugged it in. The amp takes a standard mini plug. I use a small portable speaker mp3 FM radio as my input. Output sound is perfect for my space. Loud enough for neighbors to hear. ## Frequently Bought Together - 2Pcs Digital Amplifier Board,TPA3116D2 Dual Channel Audio Stereo AMP High Power Digital Subwoofer Power Amplifier Board 2x50W 5V 12V 24V for Store Solicitation Home Theater Square DIY Speakers - Gikfun 2" 4Ohm 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1725 - HiLetgo 2pcs mp3 Player Mini MP3 Player Audio Voice Module TF Card U Disk Board for DFPlayer Audio Voice Music Module --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/226242364-tpa3116d2-stereo-amplifier-boards-2-pack-2-x-50w](https://www.desertcart.sc/products/226242364-tpa3116d2-stereo-amplifier-boards-2-pack-2-x-50w) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-10-25*
