Also there is another version of the board called BlackPill - link. I bought both items on, search for «STM32F103C8T6 Minimum System Development Board» and «ST-Link v2 mini», for example this and this. But its not expensive also, total price for mini board + programmer is still comparable with Arduino clones. One big drawback is that you need additional external programmer. Here is the comparision of Arduino Leonardo (which is a most likely candidate for our goal) and STM32F103C8T6 (which I used)Ģ x 12-bit, 1 μs A/D converters (7 channels)Īs you can see, specs for stm32f103c8 are not so bad. Already having some experience with Arduino boards, I know their capabilities and decided to route a STM32 way this time (mostly to learn something new though).
#PCB PEDAL UPDATE#
UPDATE 04.2021: Updated download links by request, all files should be available now.During building my pedals, I decided to make my own pedal controller using cheep and affordable components. Wiring Diagram Note: potentiometer shafts on the wiring diagram are positioned away from the viewer.ĭownload Below I have included all needed files to build this project. It is easy to connect all off-board components and position them how you want to in a case. Wiring Diagram I have made a wiring diagram to make building this pedal as simple as possible for you.

I will have the picture right down below, but if you want, you can download Sprint Layout files in the end of the post. The PCB turned out to be almost the same as the Matsumin version, but I was sure that it was right with all the measurements. I can say, that I had genuine fun while trying to route the PCB. PCB As for the PCB, I could have used the one on the Matsumin website, but I wanted it to be done by me just to be sure and have better quality for a print. Schematic For principle schematic, I found a good one on a Japanese website:
#PCB PEDAL TRIAL#
After some trial and error, I finally got the schematic working. Considering I was only starting out in the DIY projects, this pedal build was rather hard. We will not go into any details right now, maybe in another post. These opamps are two JFET transistors in one package, but with different characteristics, which gives them difference in sound. Compared to Tube Screamer, which uses JFET transistors, Maxon OD808 uses operational amplifiers, or opamps for short. Inside there is a modified schematic of the very first Tube Screamer. This pedal has a lot of history and is as popular as a Tube Screamer TS9 by Ibanez. Introduction Original Maxon Pedal Today I want to present you my second project – DIY Maxon 808 Overdrive pedal.
