Breadboard adapter for BT audio modules BM83
I'm working on a project that includes bluetooth audio and I want to try various bluetooth audio modules. Bluetooth modules are always in the form of a board designed to be soldered on the main PCB so they are not compatible with a breadboard. This makes prototyping with them really difficult.
It's open source, and same as all of my creations, source files are on my GitHub page. The link can be found below in the documentation section. Board schematics are made in KiCad OSS SW. The board design is tested by me. If any bugs show up, I will ship it fixed or the fix will be documented here (in case it cannot be fixed in advance).
8 buttons (reset,MFB, select, VOL-/+ next/prev son, play/pause)
2x Mic input (3.5mm jack) with support circuits
AUX input (3.5mm jack) with support circuits
micro USB port for power and DFU upload of firmware
all pins of module are routed to 2.54mm(0.1") headers
solder jumpers for using single-ended microphones
option for ele. capacitors to be used on output line(not required if headphones are used)
optional smd components include(+3$):
4x 3.5mm stereo jack for outputs, aux and mics
passives (caps, resistors, 2xLED)
option for soldered components (not BM20) is + 5$
spin-off as part of the project:
None of the option includes the actual bluetooth module.
