Therefore, each kit should contain some kind of gateway to allow an easy pre-installation of the <a href="https://github.com/iotempire/iotempower">IoTempower</a> framework. If available for a decent cost this should be a Raspberry Pi 4 with at least 2 GB RAM, a good 3A USB-C power supply, and a fast (at least Class 10) 8GB SD-card. This can also be replaced with another single board computer, an old laptop or even Desktop. Old HPs or Lenovo Thinkpads with at least a dual core Intel i3, i5, or i7 have proven a very good reliable replacement. A Raspberry Pi (starting from Version 3) and some old laptops support running in Access-Point mode and can supply a local wireless network for a student team working with it. If the gateway does not support WiFi in accesspoint mode, a (small) WiFi router (best one that supports <a href="https://openwrt.org/">OpenWRT</a> - this one is often available for a good price: <a href="https://www.gl-inet.com/products/gl-mt300n-v2/">https://www.gl-inet.com/products/gl-mt300n-v2/</a>) should be also supplied.</p>https://ulno.net/iot/hardware/Mon, 24 Apr 2017 00:00:00 +0200https://ulno.net/iot/hardware/<figure class="fig fig-right" style="width:50%"><a href="https://ulno.net/pics/iot/doorbell.jpg"><img src="https://ulno.net/pics/iot/doorbell.jpg" alt="Smart doorbell." loading="lazy" decoding="async"></a> <figcaption>A (very) smart doorbell (vector image <a href="https://ulno.net/pics/iot/doorbell.pdf">here</a>).</figcaption> </figure> <p>For the current kits I use for teaching, check out this steadily updated docoment on google drive: <a href="https://docs.google.com/document/d/11emNLk06Op-Al7k74xBO8sQfSMf_15743DfmCw1Fc4k/edit">hardware document on google drive</a></p> <p><strong>Navigation</strong></p>
