Hermes-Lite2 Releases

The Hermes-Lite 2 is an entirely open source and open hardware project. This includes not only the source files, but the tools used to design the Hermes-Lite as well as all production files. Full releases are found on github. Because this project is entirely open source and open hardware, there are several ways to realize a Hermes-Lite 2. A goal of this project is to explore and pursue new and inexpensive ways to have open hardware manufactured in small batches.

Do not be concerned if a release name includes the word beta. The Hermes-Lite 2.0 has been released starting with beta2 at the end of 2016. All beta versions will be supported in the future. The term beta is used for a functioning unit, similar to what is described here. Recent releases have switched to append buildN where N is the group buy build number.

Group Buys

From time to time, group buys are organized. To express interest in a future group buy and add your name to the list, please send mail to hermeslite at gmail.coim. Also, check or post to the Hermes-Lite Google Group.

Group buys are typically for at least 25 units. Recent group buys have had most of the Hermes-Lite 2.0 assembled and include an option to add on the N2ADR companion filter board. This is not a boxed unit and you are still expected to do a little through hole soldering and final assembly with a separate enclosure.

About 20% is added to the price to cover a few bad or lost units. So far this has been enough to cover any accidents or field failures within 90 days of purchase, but group buys do not include a full guarantee.

Printed Circuit Boards Only

The release directories include a gerber files ready to be submitted to a PCB fabrication house. Budget PCB fabrication services may be found at PCB shopper.

The release directories also contain the files bom.standard.pdf and hermeslite.pdf. These are the BOM and schematic files used to assemble a Hermes-Lite 2. Although it is a challenging build with many surface mount components, others have built the Hermes-Lite 2 by hand. As seen from the BOM, parts cost will range from $160 to $190 dollars. Please refer to the getting started, test and build notes on the wiki for guidance with your build. You may have to refer to notes from past releases to find all the required information.

See the interactive BOM for help with hand assembly.
