== Introduction ==
The ''pros'':
Zynthian MINI kit is a cost effective approach to build a zynthian box with similar functionality to v5 kit.
'''The ''pros'':'''
* Lower price
* Lower price
* Possibility of inserting a standard RPi-hat.
* Possibility of inserting a standard RPi-hat
* Smaller format. It's slighty higher than V5, but quite shorter.

The ''cons'':
'''The ''cons'':'''
* No audio input
* No audio input
* No amplified headphones output
* No amplified headphones output
* No separated TRS audio connectors. No balanced output/input
* No separated TRS audio connectors. No balanced output/input.
* No USB-B connector. Connecting to PC as USB device is more difficult, but still doable.
* No USB-B connector. Connecting to PC as USB device is more difficult, but still doable.
* Overclocking could cause over-heating. The plastic/fiber-glass case can't be used as a heat-sink
* Lower performance at medium-high ambient temperature. Overclocking could cause over-heating. The plastic/fiber-glass case can't be used as a heat-sink.
* No RGB LED feedback on push buttons

* More difficult to assemble. It requires more time and greater skills (i.e. soldering some electronic parts on the PCB)

* Not so robust. Not so cool, but ... heyyy!! MINI-V2 is also quite cool! ;-)

Zynthian ''Mini'' 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.

This will print around 3:30 hours on average commodity printers these days that can easily do 250mm/s such is Elegoo's Neptune 4 or Anycubic Kobra 2.

Then print bottom part. Lay bottom side of bottom part onto the printer bed. Use the same settings as for previous parts. Bottom part will be printed much quicker.
