It is used for service, configuration and maintenance. It is normally not required for a bike owner to have such an interface, but my curiosity was triggered to find out if I can hookup Bluetooth to my bike. -- [BOX](https://user-images.githubusercontent.com/1014001/43896685-f58adc2a-9bd9-11e8-9821-9a8bd3c760c1.jpg) -- [PCB TOP](https://user-images.githubusercontent.com/1014001/43896881-a103f028-9bda-11e8-8a23-826b529461cf.jpg) -- [PCB BOTTOM](https://user-images.githubusercontent.com/1014001/43896903-ae41b82e-9bda-11e8-99b4-9aa84fdd4943.jpg) -- [BOX INNER SIDE TOP](https://user-images.githubusercontent.com/1014001/43896922-be125c4a-9bda-11e8-8097-daa525b39b0f.jpg) -- [BOX INNER SIDE BOTTOM](https://user-images.githubusercontent.com/1014001/43896908-b4724cd6-9bda-11e8-948c-682df6467245.jpg) -- [BOX BACK SIDE](https://user-images.githubusercontent.com/1014001/43896913-b80eea16-9bda-11e8-8450-f36e1a5e1dfe.jpg) -- [BOX SIDE VIEW](https://user-images.githubusercontent.com/1014001/43897124-60b91e7a-9bdb-11e8-816b-77eb42061afe.jpg) +Refer to the [pictures](pictures/) directory and look for all pictures that start with the prefix `SM-PCE1`. #### Super Capacitor Strangely enough the PCB has two super-capacitors.
