AdamTuraj/Hackboard7An extended Arduino Uno clone based on the STM32L476RG
Hackboard is an open-source printed circuit board by AdamTuraj, from the AdamTuraj/Hackboard repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 101 × 53.3 mm with 65 parts on 83 nets, routed with 565 tracks and 69 vias.
It is built around the STM32L476RGT6, MSD-1-A and AP7361C-33E, with the USBLC6-2SC6, CC0603KRX7R7BB105 and CRGCQ0603J220R among its other parts. Its parts include 20 capacitors, 14 resistors, 8 connectors, 6 diodes and 4 ICs. It belongs with the STM32 boards of this library.
Every hardware hacker needs a development board. So why not make your own overkill one?
The Hackboard is a "one board fits (almost) all" development board with many useful features to ensure it works with all projects! Whether you need to drive a motor, listen through a microphone, play music on a speaker or use various peripherals, the Hackboard has you covered.
Running on Arduino or STM32CubeIDE, you can take full advantage of Hackboard due to its low learning curve. On top of all these features, it is super efficient and can easily run off a 9v battery for many hours. Still not interested. Get a larger overview of the features below!
Here's a deeper dive into the features:
[!WARNING] This board CANNOT be assembled through JLCPCB due to many of the parts not being available at LCSC. Alternatives are using different PCB manufacturers or assembling it yourself
The BOM can be found in the production folder or the Digikey list here.
The extra MOSFET and related circuitry on pin 13 does not need to be soldered for the board to function (hence the DNP).
JP1 and JP2 are jumpers that can be soldered/desoldered to achieve certain functionality.
JP1 must be bridged to enable the addressable LED's. JP2 must be left unbridged if the MOSFET is soldered.
[!NOTE] You must have an STLink to continue. They can be bought standalone or with a Nucleo board
A more detailed guide will be written up shortly. For now you may use STM32Duino to make it work with Arduino.

It measures 101 × 53.3 mm and has 4 copper layers, 1.61 mm thick.
65 parts, built around the STM32L476RGT6, MSD-1-A, AP7361C-33E and USBLC6-2SC6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the AdamTuraj/Hackboard repository on GitHub, at the commit this page was made from: the board is Hackboard.kicad_pcb and its schematic Hackboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
