The new design STM32F103zet6 core board, the entire layout is reasonable, simple and generous,

The characteristics are as follows:

1. The supporting chip is the new original STM32F103zet6, 72M main frequency, LQFP144 packaging, FLASH capacity in the film: 512K, SRAM capacity in the film: 64K, all pins have been led to expand.

2. A power indicator.

3. Two user indicators.

4. Standard 20 -needle JTAG sockets can connect to STLINK, Jlink, Ulink and other emulators.

5.8m working crystal, official parameters, PLL multiplier inside the chip, the maximum frequency of the chip is 72m.

6.1 reset buttons provide external reset function of hardware.

7.2 user keys to facilitate beginners to do the most basic learning programming.

8. A ASM1117-3.3 voltage stabilization tube, provides a 3.3V power supply for the motherboard work, uses capacitor filtering to ensure the stable operation of the system.

9. The MINIUSB interface is uniformly adopted by the MINIUSB interface. The store also has a USB to TTL download cable with a miniusb interface.

10.2 double -row 30p*2 —2.0mm spacing interface, all the expansion feet of STM32F103zet6.Give 2 2.0-2.54mm transfers separately, which is convenient for expansion to 2.54mm spacing.

The scooping on both sides can be up or down, and the delivery is not welded by default. The delivery of the needle is convenient for users to welded according to their own needs.

11. Provide PCB diagrams in PDF format and PDF format, PCB size positioning diagram in the Protel format, which is convenient for the bottom plate design!

The size of 42*72mm is small enough to fully expand all pins that need to be used.

The PCB board adopts the golden technology, which is more convenient to weld!

Direct USB port to get electricity, no other power supply is required

The core board does not provide technical support at low -cost sales. The development board defaults to write the LED light flashing procedure. After receiving the goods, you can power on the first time to verify whether the core board works!Intersection

Provide serial ports and assembly lamp programs, and provide PDF format schematic PCB diagram.In

This product cannot be called a learning board, it can be called a development board or a core board, and it is only for developers to improve development speed.

Our shop is profitable and sells. Before the post is issued, only the appearance detection, the writing test, and the simulation connection detection.Please test it in time after the goods, test first and then welded!Intersection

Communicate in time if there are problems.The problems that customers can solve should be solved as much as possible.
