The lab's boards are carriers for the C865 module: Thundercomm's (the EB5 on the bench [E1]) or our own headset carrier.

How the pieces nest: SoC inside SOM inside carrier

The lab's C865 SOM held beside the EB5 carrier, labelled
The big board is not the RB5 kit board, which is a credit-card-sized 96Boards card [T2].
| Name | What it is |
|---|---|
| QRB5165 | The chip: Snapdragon 865 silicon sold for robots [Q1] |
| C865, "TurboX C865", "RB5 SOM" | Thundercomm's module: the chip plus memory, storage, power and radio on one plug-in board [T1] |
| RB5, "Robotics RB5" | Qualcomm's robotics dev kit: the module on a small IO board, plus its Linux software [T2] |
"We are designing hardware for the RB5" means we are designing a carrier for the C865 module.
