About the STLinkV2 PCB

STLinkV2 is an open source STM32 PCB design by grumat, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 73.7 × 38.1 mm, with 59 components from 40 distinct parts.

Its main chip is the STM32F103CBT6, from the STM32 family. Other key parts include the AD8531ARTZ, 74LVC2T45DC and SRV05-4. By type, the board carries 25 capacitors, 17 resistors, 7 ICs, 5 connectors, 2 diodes and 1 crystal.

It belongs with the usb & debug tools designs in this gallery.

This project is a redesign of the original STLinkV2 project, using the same components of the Glossy MSP430. The reasons for this redesign are: - The original STLinkV2 cannot be found anymore, as it was replaced by a Version 3 using a much faster controller - Clones have no support for variable target voltages. - Also no support for a UART connection, which in this version, borrows the SWIM connector for that purpose.

STLinkV2: common questions

What microcontroller does the STLinkV2 use?

The STLinkV2 is built around the STM32F103CBT6, from the STM32 family.

How big is the STLinkV2 PCB?

The STLinkV2 measures 73.7 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the STLinkV2?

59 components, from 40 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 STLinkV2 design files?

From the grumat/glossy-msp430 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 STLinkV2 design in my own project?

Yes, under the terms of its GPL-2.0 license, which grumat chose for the repository.

Can I test firmware for the STLinkV2 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.
