DIY Bluetooth Audio Receiver (case for VHM-314)

thingiverse

DIY Bluetooth Audio Receiver Case This is a cheap and convenient way to connect your phone with older audio systems which have only a wired connection (especially in cars). It also provides quite good music quality without interferences unlike many cheap devices available in shops. To make it, you'll need: 1. VHM-314 Bluetooth Audio Receiver module (to buy on eBay or Aliexpress for few bucks) 2. 5V source of energy (standard USB charger) 3. AUX and microUSB cables to connect with audio system and source of energy Assembly is very easy, just put the module to lower part of case and close it with upper case. Remember to put some double-sided tape (1mm layer) between upper case's inner edges and module just to make sure it will stay tight (I leave a small gap there because of possible differences in module thickness and 3d printers accuracy). You can also stick a small piece of transparent tape on LED hole from internal side of upper case just to protect module from dirt.
