Core107V STM32F107VET6

Overview

Core107V is a small STM32 development board that features an STM32F107VET6 device as the microcontroller, supports further expansion. It is ideal for starting application development with STM32F family.

As a minimal ready-to-run system, the Core107V integrates USB communication interface, JTAG/SWD programming/debugging interface, clock circuit, USB power management, boot mode selection, and so on.

Furthermore, pin headers on the backside allow the Core107V to be plugged-in your application board and act as the MCU core circuit in your system. All the I/O ports are accessible on the pin headers, and the header pitch is designed as 2.54mm.

3.  MIC2075 (on bottom side): onboard USB power management device
4.  Power supply switch, powered from 5Vin or USB connection
5.  Boot mode switch, for configuring BOOT0 pin
6.  Power indicator
7.  Reset button
8.  8M crystal oscillator
9.  32.768K crystal (on bottom side), for internal RTC with calibration
10. JTAG/SWD interface: for debugging/programming
11. USB connector, used for establishing USB communication between PC and the STM32 development board
12. IO expander (including VCC/GND), all the MCU pins are accessible on expansion connectors for further expansion
13. 5Vin pinheader, 5V power supply is required when using USB HOST/OTG
14. USB jumper

• short the jumper to when using USB
• open the jumper to disconnect from I/O ports

15. VBAT selection jumper

• short the jumper to use system power supply
• open the jumper to connect the VBAT to external power, such as battery

16. VREF selection jumper

• short the jumper to connect VREF+/VREF- to VCC/GND
• open the jumper to connect VREF+/VREF- to other custom pin via jumper wire

Photos

Note:
Core107V provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
Mother board and programmer/debugger in the photos are NOT included in the price.
