Well!, It’s time to release some stuff 
This is the Z2 Main Board and it’s the core of next official zynthian kits. It features:
- A very decent power supply circuit, that can be fed with DC voltage from 9V to 48V using a good & reliable “barrel” connector. And we found a very nice power connector with switch!
- Balanced Audio Input + Output (2 channels) => Almost the same design than ZynADAC
- Headphones => We use a good headphones amplifier from Texas Instruments.
- DIN-5 MIDI-IN/THRU/OUT => Almost the same design than Zynaptik
- RTC with Battery (very accurate and ultra-low power)
- SD-Card extender, for easy accessing the SD-card
- USB-B connector for connecting Zynthian to your computer as a MIDI device
- Z2 Display Connector => Power + HDMI + Touch
- Z2 Control Connector => Power + WS32 LEDs + I2C + 6 GPIO
- Mechanized Aluminum Thermal Block => Acts as a massive heatsink that connects the RBPI’s hot surfaces to the aluminum chassis, allowing overclocking up to 2GHz without problems.
I will release the design files very soon.
Enjoy!
