About the Iskander PCB

Iskander is an open source STM32 PCB design by M-K-O-Hybrid-open-source, published on GitHub under the MIT license. It is a 2-layer board measuring 81.5 × 47 mm, with 62 components from 32 distinct parts.

Its main chip is the STM32F446RETx, from the STM32 family. Other key parts include the AMS1117-3.3, DRV8323H and LM2576HVS-12. By type, the board carries 26 capacitors, 17 resistors, 6 transistors, 5 connectors, 4 ICs and 2 diodes.

It belongs with the robotics & motion designs in this gallery.

From the project

Iskander is an open source driver for BLDC motors, the hardware support Six step commutation and FOC, still in the experimental phase but it will be ready as soon as possible

Iskander: common questions

What microcontroller does the Iskander use?

The Iskander is built around the STM32F446RETx, from the STM32 family.

How big is the Iskander PCB?

The Iskander measures 81.5 × 47 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iskander?

62 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Iskander design files?

From the M-K-O-Hybrid-open-source/Iskander repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Iskander design in my own project?

Yes, under the terms of its MIT license, which M-K-O-Hybrid-open-source chose for the repository.

Can I test firmware for the Iskander without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
