EasyMx PRO
v7
The Default MCU card that comes with the EasyMx PRO
™
v7 for STM32® package is shown on Figure 1. It contains STM32F107VCT6 microcontroller with on-chip
peripherals and is a great choice for both beginners and professionals. After testing and building the nal program, this card can also be taken out of the board socket and
used in your nal device.

Card information
STM32F107VCT6 is the default chip of EasyMx PRO
™
v7 for STM32®. It has
72MHz frequency, 256K bytes of Flash memory, 64K bytes of general-
purpose SRAM, integrated Ethernet controller, USB 2.0 (OTG, Host, Device),
80 General purpose I/O pins (mappable on 16 external interrupt), 4x16-bit
timers, 2x12-bit A/D (16 channels), 2x12-bit D/A , 5xUARTs, internal Real
time clock (RTC), 2xI2C, 3xSPI and 2xCAN controllers.
25MHz crystal oscillator. We carefully chose the most convenient crystal
value that provides clock frequency which can be used directly, or with the PLL
multipliers to create higher MCU clock value. MCU card also contains 32.768 kHz
crystal oscillator which provides external clock for RTCC module.
USB communications lines. These two jumpers, when in USB position,
connect D+ and D- lines of the on-board USB connector with PA11 and PA12
microcontroller pins. Since STM32F107VCT6 supports USB, jumpers are in USB
position.
