Need help building a cheap DIY Bluetooth module.
Hey guys, I'm reposting this as the previous for some reason the photos got mixed. I built this Bluetooth module from a Vaorlo 5.4 bt module, it has SBC and AAC codecs, and this pack of 2 "30pin to aux" adapters. One adapter I just shortened the cable and soldered an L shaped plug just in case the 30 pin mod didn't worked, but it worked beautifully. The 30 pin fits inside the Vaorlo shell and you just need to cut the hole of the 30pin and solder the 3 wires to the jack inside the module. But I'm still using the module battery it is a small 140 mah 3.7 V battery. I can see that the 30 pin adapter has extra pins and even the adapter have some pads that probably work, but I don't know which pads I can use to feed the module, also, I think the ipod delivers 5V and the module battery is 3.7 V. Also I think I can use the usb C to charge the ipod too. But that's way ahead of my knowledge. If someone can help me figure out we can create an open source BT/USB-C charging module. By the way this whole contraption cost me around 15 bucks. 7 for the BT module and 8 for the 2 adapters pack.
