With micro USB port, support micro USB 5V power supply. Input reverse connection protection. Dual audio output terminal. Full Surface Mounted Technology. Support antenna external connection (suitable for mounting inside a metal box). Terminals: Power Supply Input Terminal: 5V Micro USB port & 5-12V external power supply wiring terminal; Audio Input Terminal: 3.5mm AUX input terminal & 2.54mm 3P AUX input terminal; Audio Output Terminal: 3.5mm jack socket & 2.54mm 3P audio output terminal. LED Indicator Instruction: Quick flashing: waiting for a connection Keeps on: connected Slow flashing: audio playing Usage: This module is a blue~tooth receiver module which outputs standard analog audio signals. At the same time, the addition of AUX input terminals facilitates the connection of other audio sources. When there is no blue~tooth connected, the AUX terminal and the OUT terminal are directly connected. When there is blue~tooth connected, the blue~tooth audio signal is output from the OUT terminal, and the AUX terminal and the OUT terminal are disconnected. Note: This item is a blue~tooth receiver board, if used for speakers, please connect an amplifier. Otherwise, there will be distortion at high volume. Package Included: 1x Blue~tooth Board Review: 5-stars, no complaints - I am a purchasing consumer reviewing a product I purchased. I am not receiving anything for posting this. 5-stars easy. No complaints, I bought two Some of the reviews below state this board is a 24-35V device. It uses a GH27G / AZ1117E power input chip, that's only designed for 13V max. I STRONGLY DOUBT this device can withstand over-voltage by a factor of 2x-3x. The desertcart product description seems correct at 12V. Disclaimer: I only power mine with a standard 5V micro USB cable. I haven't actually tried it at higher voltages. [5/8/25] 2 Month review. I stand by everything posted below. After 2 months this BT board has been absolutely bomb-proof reliable. I use it every night, all night to listen to relaxing music and fall asleep. The BT radio has never dropped out or dis-connected from my old iPad. The analog side of the circuit has been just as reliable. Outstanding. [3/21/25] After several more days/nights of critical listening I stand by all my initial impressions below. I don't know if its component burn-in or what but something slightly "bloomed". The sound image is more layered now compared to a Y-RCA cable straight out of the ipad headphone jack. The harmonic content surrounding notes, room acoustics and ambience in recordings seems slightly more distinct now. The sonic differences between L/R Multi-tracked instrumentation are a little bit clearer and easier to hear. There also seems to be more energy at the extremes of the sonic spectrum. Below ~45Hz is bloomier and more resonant. Above ~6K seems more delicate, articulate and refined. The difference is very slight mind you, maybe an ~8% perceptional difference (if that). It's (honestly) probably just my hearing perception adjusting and picking it up for the first time. This is my finding with all my headphones, none of which are commonly known to be high-detail revealing. I am going to dust off my old AKG K701 and Koss A250 today and give a listen with those. Those are my most analytical / accurate headphones. FWIW I am not a 100% believer in electronic component "burn-in". I know for me personally my hearing perception sensitivity can vary greatly. I am a STRONG believer in blind A/B listening tests, and that's really the only way to validate my impressions. The eyes can strongly influence what the brain / ears hear. I attached a pic of my electrical tape mod to help dim the blue flashing LED. The instructions have an illustration with headphones plugged directly into the TRS output jack. I tried that and it was awful. Probably a gross impedance miss-match with lower Z cans and IEMs, and a severe power deficiency with my 300 ohm HD650. I would only use this as a line-level device. [3/13/25] I power with a micro-USB plug. Plug into my Larocco PPA headphone amp with a cheap RCA "Y" cable. I use an ipad as BT source for ALAC and 320k mp3 files. Absolutely no issues what so ever after 3 nights of critical listening. The circuit is "black background" silent. No hiss, no hum, no clicks/pops or digital artifact noises of any kind regardless of ipad volume setting. No radio frequency noise / interference either. Sound quality seems to be well balanced no offending boost or cuts to the sonic spectrum. It is a very "dry / uncolored" sounding circuit when used as a line level device. I A/B compared it with a plain "Y" cable out of my ipad... and I really could not hear any significant sonic differences. These impressions were made using sennheiser HD650, Koss KSC75, Grado HF-1, Truthear Zero Red, JBL T110. Frankly I am pleasantly surprised. BT connectivity / reliability has been solid... as reliable as the cheap RCA-Y cable it replaces. I bought two of these so I could use my headphone amps with BT. This will help reduce some of the wires and clutter on my desk and nightstand. I will probably mount one in a small project box and just use a micro-USB plug for power. The second one I think I can squeeze in the second amps enclosure, and tap into the 12V DC part of the circuit. The blue LED is CRAZY bright at night. I cover it with a small piece of black electrical tape and it helps. I wish it were the opposite, solid ON when connected to BT and flashing when waiting to be paired. But that's not nearly major enough to take away a star. Reliability of course remains to be seen. I will post dated updates to this review as my opinions change. Review: Excelente para proyectos/actualizaciones - Usé éste módulo para actualizar un amplificador Sony TA-A50 al hacer la interfase a una entrada que originalmente es destinada para un sintonizador de radio. Naturalmente la instalación requiere de soldadura y un vistazo al manual con los diagramas eléctricos para saber el lugar para instalar la conexión. Suena bien, cumple su función. Me agrada que el módulo tenga provisión para antena externa, pues instalar una ayudará a incrementar el rango de operación. Ampliamente recomendado. ## Features - PARAMETER --- input voltage range DC 5V-12V, support micro USB 5V power supply; blue~tooth version 4.2. - APPLICATION --- headphone, speaker, home stereo system DIY. - INPUT METHOD --- 3.5mm AUX input & 2.54mm 3P AUX input. - OUTPUT METHOD --- 3.5mm audio output & 2.54mm 3P audio output. - LED INDICATOR --- indicates status of waiting for a connection/connected/audio playing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07P94Z9XR | | Best Sellers Rank | #68,179 in Electronics ( See Top 100 in Electronics ) #51 in Home Audio Receivers | | Brand Name | DROK | | Customer Reviews | 4.4 out of 5 stars 508 Reviews | | Included Components | board | | Item Dimensions | 5.6 x 3.3 x 0.4 centimeters | | Item Weight | 0.03 Kilograms | | Item dimensions L x W x H | 5.6 x 3.3 x 0.4 centimeters | | Manufacturer | DROK | | Material Type | Printed Circuit Board (Pcb) | | Maximum Supply Voltage | 12 Volts (DC) | | Maximum supply voltage | 12 Volts (DC) | | Minimum Supply Voltage | 5 Volts | | Minimum supply voltage | 5 Volts | | Model | 200367AFA | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Number of Channels | 2 | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 200367AFA | | Specification Met | Unspecified Standards | | Unit Count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Item dimensions L x W x H:** 5.6 x 3.3 x 0.4 centimeters - **Manufacturer:** DROK - **Maximum supply voltage:** 12 Volts (DC) - **Minimum supply voltage:** 5 Volts - **Voltage:** 12 Volts ## Images ![DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY - Image 1](https://m.media-amazon.com/images/I/81YbxwcflCL.jpg) ![DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY - Image 2](https://m.media-amazon.com/images/I/719YIgHfWYL.jpg) ![DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY - Image 3](https://m.media-amazon.com/images/I/71bUhE67I4L.jpg) ![DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY - Image 4](https://m.media-amazon.com/images/I/71JtVI0GGfL.jpg) ![DROK Blue~Tooth Board, 12V Audio Receiver Blue~Tooth Module DC 5V-12V Portable Wire~Less Electronics Stereo Music Receive Circuit Chip with Micro USB Port for Headphone Speaker Home Sound System DIY - Image 5](https://m.media-amazon.com/images/I/71t8jXh84HL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5-stars, no complaints *by G***. on 10 March 2025* I am a purchasing consumer reviewing a product I purchased.
