Introduction
The STM32100B-EVAL is an evaluation board for STMicroelectronics ARM
core-based STM32F100VBT6 microcontroller. It is designed as a complete development
environment with HDMI CEC, two I
8 KB internal SRAM and 128 KB internal Flash, and JTAG and SWD debugging support.
With a complete range of hardware evaluations features, the STM32100B-EVAL board is
designed to help developers evaluate all device peripherals (such as HDMI CEC, motor
control, LCD, MicroSD Card
own applications. Extension connectors make it possible to easily connect a daughterboard
or wrapping board for a specific application.
An ST-LINK is integrated on the board as an embedded in-circuit debugger and programmer
for the STM32F100VBT6 MCU.
