ขาย stm 32 core board stm32 f 103zet 6 บอร์ดสําหรับการเรียนรู้ ราคาที่ดีที่สุด

Features are as follows: 1. The supporting chip is a brand new original STM32F103ZET6, 72M main frequency, LQFP144 package, on-chip FLASH capacity: 512K, on-chip SRAM capacity: 64K, all pins have been led out for easy expansion. 2. A power indicator. 3. Two user indicator lights. 4. Standard 20-pin JTAG socket, you can connect to STLINK, JLINK, ULINK and other emulators. 5.8M working crystal oscillator, official parameters, PLL frequency multiplication inside the chip, the chip maximum frequency is 72M. 6.1 reset buttons provide hardware external reset function. 7.2 user buttons to facilitate beginners to do the most basic learning and programming. 8. An ASM1117-3.3 voltage regulator tube provides 3.3V power supply for main board operation, and uses capacitor filtering to ensure stable operation of the system. 9. The usb interface and com-TTL interface both use the miniusb interface. The shop also has a usb-to-TTL download line with a miniusb interface, which can be used for power supply, download, and serial communication at the same time! 10. Two double-row 30P * 2-2.0mm pitch interfaces, all the stm32F103zet6 external expansion pins are led out. Two 2.0-2.54mm adapter boards are presented separately, which is convenient for expansion to 2.54mm pitch. The pin headers on both sides can be up or down. The delivery is not soldered by default. The pin headers are distributed to facilitate users to weld according to their needs. 11. Provide schematic diagram in pdf format and pcb diagram in pdf format, PCB size positioning diagram in protel format for easy baseboard design! The size 42 * 72mm is small enough to fully extend all the pins that are needed. Direct USB port to get power without other power supply. The low-cost sales of the core board do not provide technical support. The development board defaults to the flashing program of the LED light. After receiving the goods, you can power on to verify whether the core board works! ! Provide serial port program and running light program, provide pdf format schematic diagram pcb diagram. (The above information is sent by mail or online transmission, CD-ROM is not distributed) This product cannot be called a learning board, but can be called a development board or a core board. It is only used by developers to increase development speed. Our store is small but profitable, only for appearance inspection, programming inspection, and simulation connection inspection before sending. Please test in time after the goods arrive, test and solder the pins first! ! Communicate in a timely manner if there is a problem. The customer can solve the problem, try to ask the customer to solve it by themselves. Note: Due to manual measurement, please allow 1-3mm different. Due to different displays and different lighting, the image may not reflect the actual colors of the project. Thank you for your understanding.
