# RB3gen2

```{include} common-alert-enablement.md
```

The
[RB3gen2](https://www.qualcomm.com/developer/hardware/rb3-gen-2-development-kit)
DUT can be automated using the [RPi and 96 boards](/hardware/mibs/rpi-96b.md) MIB.

## Components

The following components are required to fully automate the board:

- [RPi and 96 boards MIB](/hardware/mibs/rpi-96b.md)
- Short RJ45 network cable
- USB-C male to USB-C male cable
- USB-A male to MicroUSB male cable
- For the OTG USB-C to MicroUSB connection:
  - [USB-A male to USB-C male cable](https://www.amazon.co.uk/dp/B09V2PNY74)
  - [Micro USB OTG to USB-A Adapter](https://www.amazon.co.uk/dp/B09BCWN3KT)

## Hardware modification

In order to automate recovery, the DUT hardware should be modified.

```{admonition} Hardware modification
:class: warning
The DUT will not be automatizable without this modification.
```

### DIP switches

Set the DIP switches as in the picture below.

```{figure-md}

```

### EDL button

A two-wires cable should be soldered around the [F_DL button](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-251/rb3_gen2_force_edl_mode.html).
This will be used to drive the value high or low to trigger recovery.

### Configuration

Set the voltage level switch on the top of the MIB to 1v8.

### Recovery

Connect the recovery wires cable to the RPi-96 MIB header labeled `VBTN_A`.

```

### Network

Connect the RB3gen2 network interface to the LAA private network interface.

### Power

The RB3gen2 gets power directly from the 96boards header interface.

### Serial

Connect a USB cable from the carrier board MicroUSB port to USB `Port 4` on the SIB as shown above.

### USB

Connect the LAA `USB OTG` port (front facing) to the RB3gen2 MicroUSB port shown in the picture above.

### Flashing

Connect a USB-C cable from LAA `Port 1` (facing upward) to the RB3gen2 USB-C port shown in the picture above.
