Introduction
MMstm32F103Vx is universal minimodule for the STM32 Cortex-3 microcontrollers
from STMicroelectronics. This microcontroller is available in the TQFP100 case which
is difficult to apply to prototype and amateur circuits due to the compactness of pins.
We have undertaken an attempt at placing it on a board of 61x37,5mm with a layout of
leads which matches the commonly available prototype circuit boards. In addition, we
have included 3.3V voltage regulator, a Serial Flash memory with a capacity of up to
8MB, a circuit monitoring the supply voltage and clock generator for microcontroller. All
ports and signals of the microcontroller are lead out by means of two-row pin
connectors with 0.1’ pitch. This minimodule is not only an adapter but a complete main
board for STM32F103VB. It needs only a connection to the supply voltage and to the
JTAG programmer and we can start loading 128kBytes of Flash memory of the
microcontroller.
Through integration of the peripherals with the microcontrollers on one board, the
application of this module can lead to a shorter design period and facilitate the
construction of systems based on ARM microcontrollers, by eliminating the need to
design the printed board. The module is supplied with example software.
The MMstm32F103Vx minimodule can be also used in didactic laboratories of
informatics colleges and universities, and can be also used to build circuits realizing
thesis projects.
