Hi, The Boya BY-GM10 condenser microphone is fitted with a mini USB plug and designed to be an external microphone for a GoPro Hero 4. Am I right in assuming the mini USB connection is wired wrongly to work on the Olfi or should it work OK?
Also would an “off the shelf” mini USB Male To 3.5mm Female Jack Cable work on the Olfi and allow me to connect a 3.5mm wireless-type microphone, or would I have to make a custom 10 pin USB lead?
GoPro do not utilise the same mic setup as us, therefore no GoPro compatible mic will work as is. The USB connection would need to be re-wired to make it compatible. Pins 8 and 9 control the switch over to the external mic capability (see pic) – I believe GoPro Mic pins may attach to pins 3,4 and 5 (including GND)but don’t quote me on that!
If you wanted to attach an external mic using a 3.5mm jack connection so that you can use any microphone you like that has a 3.5mm jack, this is the only listing that i know will work as we utilise the same pin setup. Any mic advertised which says it will work with a GoPro will not work with the Olfi.
