Zynthian Mini kit is a cost effective approach to build zynthian with intention to give opportunity:
* to zynthian developers to get functional zynthian similar to v5 where they can do most of the testing
* to zynthian developers to get functional zynthian similar to v5 where they can do most of the testing
* to musician to get to know zynthian and learn their features before deciding to but the professional kit
* to musician to get to know zynthian and learn their features before deciding to buy the professional kit

* all connectors are easy to reach (V1 does not have RPI connectors aligned to the edge of the PCB)
* all connectors are easy to reach (V1 does not have RPI connectors aligned to the edge of the PCB)
To save the cost of building the Zynthian MINI, we had to sacrifice certain features that some professional musicians would need on the stage such as:
* no audio-in
* no TRS audio connectors
* not best in the class DAC for audio out
* no rigid metal case
* no zynaptik analog inputs
Zynthian is currently at version 2. Previous version 1 was more similar to official V4 kit with only 4 buttons but it is not maintained anymore.

== Configure Zynthian MINI V2 for testing ==
Download the latest zynthian development branch from os.zynthian.org following this [https://os.zynthian.org/2024-05-04-zynthianos-bookworm-aarch64-oram-2405.zip link].
Flash this image to sd card with a size of at least 32GB.
Put the SD card into raspberry Pi and connect zynthian mini to power by connecting USB-C power adapter to Raspberry Pi board. Use correct power adapter.
Optionally you can also connect zynthian mini to network using network cable attached to Raspberry Pi.
Wait for zynthian to start. Zynthian screen will be wrongly oriented, encoders and their push button will not work. Also none of 20 additional push buttons will work. For all this to be configured we need first to get all latest software updates that will also include required options to configure zynthian mini v2.
=== Connect to zynthian web UI to update zynthian software ===
If you have not connected zynthian to your network using network cable you will need to configure zynthian wifi first. You can do this on the screen even though screen is wrongly oriented by
* touching the top corner of the screen
* selecting admin option
* selecting wifi enable option
* selecting your network
* entering your wifi password
You will need to find out zynthian IP address by long touching top left corner of the screen where it says "Mixer" which will open the admin page and then scroll down to Network info. Select network info where you will be able to see IP address if zynthian is properly connected to your network.
Open browser on another computer and type zynthian IP addrese into browser's address bar. You will be prompted to login to zynthian web configuration UI. Oram default password is "opensynth".
=== Update zynthian oram software ===
After loging to zynthian web configuration UI click on "Software" from top navigation bar and click on "Update".

Wait until the software is updated. You need to make sure that it says "Update Complete" at the end of the logs.
[[File:Config-step-02.png|400px]]
Once you have updated the software restart the zynthian by clicking "System" option from top navigation and then selecting "Reboot".

=== Configuring zynthian mini v2 as a kit ===
Once zynthian oram software is updated and zynthian restarted you can configure most of zynthian MINI hardware simple by selecting the Mini V2 Kit. To do that click on "Hardware" from top bar navigation and select Kit option. On this screen select "Mini V2" kit and Save.
[[File:Config-step-05.png|400px]]
Once it is saved you will need to click on restart at the bottom of the Save page.
[[File:Config-step-06.png|400px]]
Now all hardware is configured and should work properly. Screen orientation should be correct, proper sound card selected, all encoders and switches should work properly. What is left is just few screen UI adjustments.
=== Adjusting UI for Zynthian layout ===
Zynthian Mini V2 has all encoders on the right and therefore corresponding UI widgets need to be always on the right instead of left and right that is default configuration. Also by default cursor is visible which is not necessary when there is a touch screen. To set these two options click on "Interface" from top navigation bar and select "UI options". On this screen set the field called "Graphic layout" to "Knobs at right side (Z2, V5, MINI)" and also deselect "Enable cursor" option.

Restart the Zynthian mini after the all configuration is done.
Once everything is configured and working it is a time to put zynthian into the enclosure.
