MSPBMP
About the MSPBMP PCB
MSPBMP 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 62 components from 39 distinct parts.
Its main chip is the AD8531ARTZ, from the STM32 family. Other key parts include the AMS1117-3.3, 74LVC2T45DC and TXS0108EPWR. By type, the board carries 29 capacitors, 18 resistors, 5 connectors, 4 ICs, 2 diodes and 2 inductors.
It belongs with the usb & debug tools designs in this gallery.

The first build option, is a design based on the ST-Link V2 form factor. So, one can buy some cheap ST-Link V2 clone, discard the main-board of the clone and install a new hardware on it, to reuse the housing, which is very pretty and has an additional connector that can be used as a serial port. Besides, recent clones are coming without branding, which is perfect in our case:

MSPBMP: common questions
What microcontroller does the MSPBMP use?
The MSPBMP is built around the AD8531ARTZ, from the STM32 family.
How big is the MSPBMP PCB?
The MSPBMP measures 73.7 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the MSPBMP?
62 components, from 39 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 MSPBMP design files?
From the grumat/glossy-msp430 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the MSPBMP 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 MSPBMP 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.
