HC-06 Bluetooth Module Housing

thingiverse

I got a HC-06 Bluetooth module for wirelessly connecting to my PixHawk flight controller. Since using an unprotected board within my copter poses a danger, I designed a protective housing for it. The opening for the connector pins is asymmetrical with more space in one direction. This design feature is intended to ensure proper keying of the connector. To create a secure 4-pin connector, I used two BEC connectors glued together using CA. These connectors are also asymmetrical, which means they will only fit correctly when inserted in one specific direction. Looking at my photos, you can see that I've created a cable harness for connecting both Micro Minim OSD and HC-06 modules to my Pixhawk Mini Telem port in parallel. To prevent overloading the Pixhawk power supply, I added an extra 5V power cable that goes directly to the UBEC. You can find the design for the Micro Minim OSD housing on https://www.thingiverse.com/thing:3861556. Currently, I'm using two servo connectors in a similar setup, with the same CA glue attachment method. UPDATE: I discovered that there are actually two versions of the HC-06 module available. The first version has a board length of approximately 36mm, which my original housing was designed for. However, the second version measures about 39mm in length and is slightly wider, requiring a different housing design to accommodate it.
