<h1>Hardware<a class="headerlink" href="#hardware" title="Permalink to this heading"></a></h1>
<p>This section contains the documentation needed to build an OhmPi.
The OhmPi is composed of different modules:</p>
<ul class="simple">
<li><p>a measurements board (‘mb’): that measures the current and voltage and modulates modulate the injected current</p></li>
<li><p>0, 1, … or n multiplexer boards (‘mux’): that addresse different electrodes</p></li>
<li><p>a power supply (‘pwr’): either a 12V battery or a more advanced power supply where we can control the voltage/current</p></li>
<li><p>a general controller (‘ctrl’): to control the measurements board and power supply (=raspberrypi)</p></li>
</ul>
<p>These module exists in different versions and can be combined using a configuration file.
You can then upgrade your measurment board or power supply for specific applications.</p>
