About the Bms test circuit PCB

Bms test circuit is an open source AVR/Arduino PCB design by Wierdwizard2587, published on GitHub. It is a 2-layer board measuring 94.5 × 58.4 mm, with 27 components from 23 distinct parts.

Its main chip is the ATTiny 85 Module, from the AVR/Arduino family. Other key parts include the AOD409, PC817 and MP1584. By type, the board carries 12 resistors, 4 ICs, 4 connectors, 3 transistors, 2 diodes and 1 switch.

It belongs with the audio, power & battery and displays & leds designs in this gallery.

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

Bms test circuit: common questions

What microcontroller does the Bms test circuit use?

The Bms test circuit is built around the ATTiny 85 Module, from the AVR/Arduino family.

How big is the Bms test circuit PCB?

The Bms test circuit measures 94.5 × 58.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bms test circuit?

27 components, from 23 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 Bms test circuit 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 Bms test circuit 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 Bms test circuit without the hardware?

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