Welcome to the KIJIMI Documentation
"As Synthtopia reports, the Kijimi is inspired by the sound of the RSF Polykobol, a rare French polysynth from the late ’70s that was only available in very limited quantities. According to Instagram posts from Black Corporation, the synth will be available both pre-built and as a DIY kit."

Product Info:
the KIJIMI Synthesizer is a product of the Black Corparation located in Tokio.
It´s available in 2 different Version:
- DIY Kit contains 12 PCBs (mostly THT) https://www.deckardsdream.com/product/kijimi-kit-preorder-run1 (total costs for the pcbs are: $999)
- Preassambled with Case ready to use https://www.deckardsdream.com/product/kijimi-built-preorder-run1 (total costs: $3749)
The DIY kit consists of 12 PCBs:
- frontpanel board
- motherboard
- 8x voice cards
- power supply board
- connectors board
The motherboard has the MCU and DACs (digital to analogue converters used to control the analogue circuitry) preinstalled, the remaining parts you have to buy yourself from a local supplier. Some DIY shops will provide full parts kits.
Most of the remaining parts are thruhole, except for power filtering ceramic capacitors, which are large (0805 size), all same value (0.1uF) and located on the opposite side of the thruhole parts on the PCB.
The frontpanel and rack case will be supplied by DIY HUB.

Don´t miss the frontpanel and case from DIYHUB http://siddarthianinnovations.bigcartel.com/
please respect your local requirements/laws for a powersupply (110V AC/ 230V AC) and
doublecheck the power input jack polarity (inside +) and
the diameter of 2.1mm or 2.5mm of the plug/jack or you learn it in the hard way 
Display OLED
make sure your OLED folow this pinout VCC-GND-SCL-SDA, very often shows the shop the correct pinout but deliver another type.
AND short the pins on the display side (where the Frontpanel is) to prevent shorts to the Frontpanel.
if you cant source the correct display (pin) use restore legs and bend they - use cable shrink tube to protect this for shorts
