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:

• 80MHz Cortex M4 Core with 1 Mb of Flash and 128 Kb of SRAM
• Abilitiy to run on a 9v battery for around 150 HOURS¹
• 45 GPIO pins
  • 2 SPI Interfaces²
  • 1 I2C Interface
  • 1 CAN Interface
  • 1 UART Interface
  • 18 PWM Pins
  • 9 ADC's (Analog pins)
  • 2 DAC's
  • 1 OPAmp
• Arduino Uno Shield Compatible
• Same hole arrangement as Arduino UNO³
• Extended header pads for easy probing
• Micro SD card slot
• PWM Addressable MOSFET capable of powering up to 54W
• 3 addressable LED's
• Barrel jack supporting up to 32V at 54W
• USB C port for flashing and power

Assembly

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).

Jumpers

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.

Work with Arduino

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.
