Manufacturing options

Enclosure

Auvidea can provide custom enclosures for its carrier boards. These enclosures provide a passively cooled solution. This solution is designed for the AGX models. With a max power draw of 35W (normal mode) the enclosure temperature reaches 55 °C while in 24 °C room temperature which is a safe temperature for Human contact. The MaxN mode (up to 90W) is not recommended as the enclosure temperature increases above acceptable levels for direct human contact. It is also possible to apply your branding on the front and backplate of the Enclosure. Auvidea has in-house capabilities of laser and milling engraving.

Branding and QR codes

Image	Note
	In the left image the label field is highlighted.

Besides the branding options for the enclosure, it is also possible to customize the label field on the carrier board. Auvidea uses the label field to engrave a small QR code and serial number to track production processes. It is possible to add your custom engravings like logos, text or QR codes to this field as a laser engraver is used.

Custom configurations

The standard carrier board configuration is designed to suit most use cases. Please see the Pinout description for customization examples like voltage configurations (3.3V or 1.8V).

We take pride in tailoring our products to your special need and are capable to adjust it in small production series. Please contact Auvidea with your special requests to work out a solution.
