Hello, I recently bought this GSM module
maybe that was a mistake but how can I connect a speaker and a microphone to it? Any ideas?
Thank you!
Hello, I recently bought this GSM module
Look for the spk+ and spk- pin for speaker connectivity and mic+ and mic- for mic connection.
take that metallic shield off, to expose the module's pin out, go for sim800L's datasheet to trace for spk+/spk- and mic+/mic-
you better be good at soldering to tap the wires out of those pins, don't forget the caps
