<p dir="auto">We are planning to connect five M0166 (AR0144, micro-coax) tracking cameras to a single VOXL 2 (not VOXL 2 Mini), and would like to confirm feasibility before ordering hardware.</p>
<ul>
<li>Use case: 360° coverage</li>
<li>Frame sync across all five cameras: required</li>
<li>Target: 1280x800 @ 30 fps</li>
</ul>
<p dir="auto">From the docs and forum threads (topics 5010, 4491, 5130), our understanding is:</p>
<ul>
<li>VOXL 2 has only 4 unique CCI buses, so with five AR0144s at least one must use the alternate slave address (0x20) via the resistor change plus an alt-address sensormodule.</li>
<li>The confirmed 4x AR0144 setup is C27 on M0173 plus one alt-address AR0144 on J8 via M0155.</li>
<li>Adding a fifth AR0144 on J8 lower (ID4) would put a third AR0144 on CCI1, so we are considering J8 upper (ID5, CCI3) via M0172 J2U instead.</li>
</ul>
<p dir="auto">Proposed layout (no ToF):</p>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>Sensor ID</th>
<th>Connection</th>
<th>CCI</th>
<th>Slave address</th>
</tr>
</thead>
<tbody>
<tr>
<td>0</td>
<td>M0173 J1 (J6 lower)</td>
<td>CCI0</td>
<td>default</td>
</tr>
<tr>
<td>1</td>
<td>M0173 J4 (J6 upper)</td>
<td>CCI1</td>
<td>alt (0x20)</td>
</tr>
<tr>
<td>6</td>
<td>M0173 J2</td>
<td>CCI1</td>
<td>default</td>
</tr>
<tr>
<td>2</td>
<td>M0173 J5 (J7 lower)</td>
<td>CCI2</td>
<td>default</td>
</tr>
<tr>
<td>5</td>
<td>M0172 J2U on VOXL 2 J8 (upper)</td>
<td>CCI3</td>
<td>default</td>
</tr>
</tbody>
</table>
<p dir="auto">Questions:</p>
<ol>
<li>Is this layout supported, or at least expected to work, with the M0173 kernel config (platform config 1)? In particular, is sensor ID 5 (J8 upper) enabled in that kernel and usable with an AR0144 through M0172 J2U?</li>
<li>Is an alt-address (0x20) sensormodule for slot 1 included in the current SDK, or only in the zip shared in topic 5010? Is there an alt-address + fsin variant?</li>
<li>Frame sync: can all five cameras be synchronized on GPIO 109? Is the sync line routed to M0172 J2U, and does M0173 J4 (ID1) need any resistor changes (similar to R10/R11 on M0188)? Is an ar0144_fsin_5 sensormodule available?</li>
<li>Can ModalAI supply an M0166 with the alternate slave address pre-configured, so we don't have to modify the module ourselves and void the warranty?</li>
<li>Are there known throughput limits (CSI / ISP / camera server CPU) for 5x AR0144 at 1280x800 @ 30 fps on VOXL 2?</li>
<li>If this layout is not recommended, what is the recommended way to run five AR0144s on VOXL 2 (e.g. M0226 or other adapters)?</li>
</ol>
<p dir="auto">Thanks!</p>
