Port107V

Overview

Port107V is an STM32 development board that features an STM32F107VCT6 device as the microcontroller, supports further expansion with various optional accessory boards for your specific application. It is ideal for starting application development with STM32F family.

Note: Optional accessory boards are NOT included in the price.

Note:
Accessory board and programmer/debugger in the photos are NOT included in the price.
Port107V supports programming through UART port without programmer.
Port107V provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
