About the DonCon2040 PCB

DonCon2040 is an open source PCB design by ravinrabbid, published on GitHub under the MIT license. It is a 2-layer board measuring 130.8 × 58.4 mm, with 99 components from 34 distinct parts.

Other key parts include the TL072, MCP3204, MCP1541-TT and TXB0104D. By type, the board carries 33 resistors, 26 capacitors, 24 diodes, 8 connectors and 7 ICs.

It belongs with the audio designs in this gallery.

From the project

RP2040 based firmware and hardware for DIY Taiko no Tatsujin Drum Controllers

While this board will still work fine, I recommend using the DonConIOmini. It hosts the same circuit using mainly SMD parts, resulting in a smaller footprint and better noise characteristics.

This board hosts a Seeed Studio XIAO RP2040 microcontroller unit and provides signal conditioning for the piezo drum triggers. The conditioning circuit is reverse engineered from the V260 SIF PCB found in the original arcades. This is also the main reason why this board uses mainly through hole parts ... for authenticity.
