About the AFPI Device V1.1 PCB

AFPI Device V1.1 is an open source NXP PCB design by Wierdwizard2587, published on GitHub. It is a 2-layer board measuring 85 × 45 mm, with 28 components from 27 distinct parts.

Its main chip is the Teensy4.0_AudioShield_REVD, from the NXP family. Other key parts include the L7805 and LM386. By type, the board carries 9 connectors, 8 capacitors, 3 ICs, 3 resistors, 2 switches and 1 transistor.

It belongs with the audio, displays & leds and power & battery designs in this gallery, and the repository also holds 1 earlier revision of it.

From the project

This is the repository for the Research and Development, Production, and assembly of the Electric Guitar MK1.

- DIY portable electric guitar with integrated digital effects and modular power/audio system - Final version features Teensy 4.0, onboard FX, rotary encoder UI, OLED display, amp/speaker output, battery or DC power, and RGB lighting - Entire build: woodwork, PCBs, 3D prints, firmware, and more - Early prototype (Mk0) failed due to poor electrical design and overcomplex hardware, rebuilt from scratch over 12+ months with newly acquired engineering and fabrication skills

AFPI Device V1.1: common questions

What microcontroller does the AFPI Device V1.1 use?

The AFPI Device V1.1 is built around the Teensy4.0_AudioShield_REVD, from the NXP family.

How big is the AFPI Device V1.1 PCB?

The AFPI Device V1.1 measures 85 × 45 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the AFPI Device V1.1?

28 components, from 27 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the AFPI Device V1.1 design files?

From the Wierdwizard2587/ElectricGuitarMK1 repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the AFPI Device V1.1 design in my own project?

The repository has no license, so all rights stay with Wierdwizard2587. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the AFPI Device V1.1 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
