Hi,
I have ordered the Carloop, Electron, and GPS. I need to add Bluetooth to the mix and I am looking for some advice.
I need one bit of clarification though: Obviously the pins of the Electron that are hanging off the end are available for my own use. However, am I correct in assuming that the unmentioned PINs that are plugged into the Carloop are also available for my own use?
Are any of the unused pins mentioned below connected to anything, can I connect a jumper to the empty female connection that is adjacent (I see that your diagram has *2 beside each, does that mean both female connectors are connected)?

I am looking to connect either an “HC-05 Bluetooth” chip or an “Adafruit Bluefruit LE UART Friend - Bluetooth Low Energy (BLE)” chip to the Electron. I was thinking of using C0-C1 or C2-C3 for my serial connection as described here:

Do you see any issue with this setup?
Thanks!
