NumWorks

<h2 id="development">Development</h2>
<p>Romain Goyet, the CEO of NumWorks, started the company in 2016. Before starting NumWorks, he was a software engineer at <a href="/facts/Apple_Inc./oTJYta3k">Apple</a> who also contributed to open-source projects such as <a href="/facts/Linux/9FvCKSTq">Linux</a>.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a>

<p>The NumWorks <a href="/facts/Graphing_calculator/GHxINXgk">graphing calculator</a> was the first graphing calculator to be <a href="/facts/Programmable_calculator/5UHx9nIg">programmable</a> using the <a href="/facts/Python_(programming_language)/YbuGqofa">Python</a> language. It features a 320x240 IPS display with a 2.8″ diagonal. Internally, it is powered by a 216 MHz <a href="/facts/ARM_Cortex-M/prW99nkV">Cortex-M7</a> processor and 8 MB of <a href="/facts/Serial_Peripheral_Interface/uSCU56eG">Quad-SPI</a> <a href="/facts/Flash_memory/Cn8JsStx">Flash memory</a>. The calculator has a 1450 mAh <a href="/facts/Lithium_polymer_battery/0I2uusoW">lithium polymer battery</a>. The calculator weights 5.9 oz (0.37 lb) and measures 8.2 cm × 16 cm × 1 cm (3.23 in × 6.30 in × 0.39 in).
</p><p>Four versions of the calculator were produced by NumWorks: the N0100 model, the N0110 model, the N0120 model, and the N0115 model. Technical limitations of the N0100 model's memory prevent any upgrade to an OS version higher than 19.5.17

<p>The calculator was specifically designed to be modded using 3D printing. 3D models, schematics, and board layout details are available to the public under a Creative Commons license.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> The software on the calculator is updated on a monthly cycle. Updates can be downloaded to the calculator from its website using <a href="/facts/WebUSB/4KT2LxG1">WebUSB</a> or by building the operating system from its direct source.
</p><p>The NumWorks calculator also includes an "exam mode" which removes all Python programs, resets all apps, and disables certain features. It can be disabled by plugging the calculator into a power source and selecting disable on the popup that appears.
</p><p>On March 22, 2019, NumWorks released an app for iOS and Android.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> It features the same functionality as the physical calculator except it does not have <a href="/facts/Persistent_data_structure/K7IpHlkR">data persistence</a>.
