About the BluePill-G431 PCB
BluePill-G431 is an open source PCB design by grumat, published on GitHub under the GPL-2.0 license. It is a 2-layer board measuring 74.9 × 59.7 mm, with 27 components from 12 distinct parts.
Other key parts include the AD8531ARTZ, 74LVC2T45DC and SRV05-4. By type, the board carries 12 capacitors, 11 resistors and 4 ICs.
It belongs with the usb & debug tools designs in this gallery.
From the project
Glossy MSP430 - Embedded GDB Debugger for MSP430
This prototype board replaces the STM32 Bluepill/BlackPill proto-board since this design had issues related to SBW protocol.
This is a non-scale prototype of the expected hardware design, which provides generous access to signal pins, enabling a better debug experience.
Meanwhile STM32G431 in BluePill-like packaging is now available, making the STM32F411 an obsolete platform.
