Overview
TIE2026 is an open-source printed circuit board by Tutu72byte, from the Tutu72byte/Guitar-effects-processor---Hardware repository on GitHub. It is a 4-layer board of 83 × 57 mm with 111 parts on 113 nets, routed with 667 tracks and 92 vias.
It is built around the TPS74501PQWDRBRQ1. Its parts include 40 capacitors, 40 resistors, 8 ICs, 7 crystals and 3 inductors. It belongs with the audio and music boards of this library.
Main components
1README
README.mdComplete hardware development of an embedded music signal processing module (Guitar Effect Pedal) from structural block diagram to circuit schematic, pcb design and generation of manufacturing files using KiCad. The projects consists of:
-
Library Creation: Created dedicated project libraries (TIE2026.kicad_sym and TIE2026.pretty) containing custom schematic symbols and footprints.
-
Schematic design: The circuit diagram contains a Microcontroller, SPI Flash Memory, ADC/DAC audio processing stages, an interactive touchscreen interface and a switching power supply (9V in, 5V and 3.3V converters and regulators and a 2.5V bias). Incorporated specific JTAG and power rail test pads for hardware debugging.
-
PCB Topology & Stack-up: Configured a 4-layer board stack-up (1.6mm total thickness) featuring controlled trace spacing (0.1mm) and a dedicated internal ground plane split between analog ground (GND_A) and digital ground (GND), thus managing a low-noise layout by segregating the analog circuitry onto the analog ground plane linked via the 10m-Ohms shunt R28.
-
Routing for High-Speed Signals & Impedance Control: Implemented single-ended 50 Ohms data lines for the Flash memory and 100 Ohms differential lines for the video interface.
-
Manufacturing Output: Generated industry-standard production packages, including extended Gerber files, Drill files, a Pick-and-Place component file and a Bill of Materials (BOM).
