# Elixir
The Elixir is part of Golioth's "Aludel" platform, a family of devices that makes it easier to connect hardware to the internet using [Golioth's Firmware SDK](https://github.com/golioth/golioth-firmware-sdk) and [cloud platform](https://console.golioth.io). The Aludel family of devices are widely used in [Golioth's Reference Designs](https://projects.golioth.io), which are end-to-end demonstrations of IoT devices targeted at different vertical applications. There is a custom hardware component--often made up of Aludel boards--as well as a Follow-Along Hardware component, which makes it easier for

Prominently featured on Aludel boards, including this one, are Click Bus headers. This is a pinout/standard from Mikroelectronika and supported by their wide range of plug-in sensor boards. We chose this standard for maximum hardware swappability, enabling our users to change to a different targeted sensor or industry vertical by replacing one or two click boards.
This board primarily targets cellular connectivity but also has the ability to connect to/interact with WiFi networks; it can also be used for supplemental features such as [Wi-Fi locationing](https://blog.golioth.io/a-2-geofence-wi-fi-location-here-com-esp32-c3-golioth-pipelines-and-n8n/). An on-board power management unit facilitates a large array of power options, including LiPo via the onaboard connector and charging capabilities, but also up to 48V input for industrial applications. There are are array of sensors and other other commonly used support ICs. Prominently featured on Aludel boards, including this one, are [headers that conform to the MikroBus standard](https://www.mikroe.com/mikrobus).

We chose this standard for maximum hardware swappability, enabling our users to change to a different targeted sensor or industry vertical by replacing one or two click boards.

## The Aludel form factor
The Aludel form factor (Originally the "Aludel Mini" form factor) is based around the [Bud Boxes CU-1937-MB](https://www.budind.com/product/general-use-boxes/utilibox-style-l-series-utility-boxes-2/cu-1937-mb). This was further customized with a milled alternative ordered custom from Digikey, [described in more detail in this blog post](https://blog.golioth.io/low-volume-high-mix-mechanical-enclosures-for-iot-projects/). There are inserts that are 3D printed to target specific applications/Click boards, and a custom PCB front panel called [the Aludel Ostentus](https://github.com/golioth/ostentus-hw), which also is OSHW.
