Overview
MultiClockDiv is an open-source printed circuit board by ijnekenamay, from the ijnekenamay/HAGIWOs_Module repository on GitHub. It is a 2-layer board of 30 × 105 mm with 36 parts on 21 nets, routed with 169 tracks and 0 vias.
It is built around the BAT43. Its parts include 11 diodes, 10 resistors, 5 connectors, 2 capacitors and 1 switch. It belongs with the audio and music boards and the AVR (ATmega, ATtiny) boards of this library.

The purpose of this is to PCB the project that HAGIWO is working on. The Kicad project files, including the circuit and panel designs, are now available. I'm just starting to learn more about circuit design, so if there are any issues with the design or the circuit itself, please let me know immediately!
！！ Note ！！
- Most projects are designed to fit 6HP, but may be larger to accommodate PCB widths.
- Please note that there is no guarantee for the PCB production itself, as there are few actual PCBs that have been produced and verified.
- Please note that there is no guarantee for the PCB production itself.
- I won't go into the code here, you can find it on the HAGIWO website.
V2044 VCF
This is a PCB version of the V2044 VCF designed by HAGIWO. This VCF uses the same 2044 IC used in KORG PLYSIX.A simple but effective filter. The circuit diagram is based on HAGIWO's original. I actually manufactured it with JLCPCB and assembled it, and it works.
！！ Note ！！
-
For the v2044 IC chip itself, I used the Coolaudio reissue version.
-
The v2044 package is SOP16, and only this part requires surface mount technology. (Might be easier than you think!)
-
See HAGIWO's original schematic for details.
-
I will get feedback and improve it.
CHORD VCO
-
This is a PCB version of the CHORD VCO designed by HAGIWO. I actually manufactured it with JLCPCB and assembled it, and it works.
-
The output is designed with Vp-p=4V, so you may feel that the volume is lower than other modules on the market. This is as designed by HAGIWO.
-
There is no control board in this project. The hardware should be mounted and wired to the panel. See HAGIWO's original schematic for details.
-
See the HAGIWO website for the Arduino code.
4chSampler
-
It was manufactured with jlcPCB and actually worked fine. However, there are a few problems such as unconnected GND and misplaced pcb's mounting holes.
-
The output is designed with Vp-p=4V, so you may feel that the volume is lower than other modules on the market. This is as designed by HAGIWO.
-
Since I used a momentary switch (tact switch) for the switch, I modified the HAGIWO code slightly. Please check the .ino file in my repository.

Questions
How big is the MultiClockDiv PCB?
It measures 30 × 105 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MultiClockDiv use?
36 parts, built around the BAT43. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MultiClockDiv KiCad files?
From the ijnekenamay/HAGIWOs_Module repository on GitHub, at the commit this page was made from: the board is MultiClockDiv/MultiClockDiv_main/MultiClockDiv.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MultiClockDiv design in my own project?
Its repository states no licence, so its author keeps all rights: ask ijnekenamay before reusing the design.
