| [title] Looking closely at the PCB | |
| [* black] On The front we can spot | |
| [* green] Bluetooth antenna (on the board) | |
| [* light_blue] Battery connectors | |
| - | [* orange] |
| + | [* orange] Murata 2x2mm RF switch connector, that can be used for RF testing |
| [* violet] U11, U13 - probably some chips behind the shield, which is (unfortunately) firmly soldered. My guess: one of them is ultra-low power microcontroller and the other one is taking care of power delivery to the board | |
| [* yellow] J1 - place for debug connector (empty in production) |
