Yahboom MCU RCT6 Development Board STM32 Experimental Board ARM System Core Board, Specification: 0.96 inch TFT Color Screen

STM32F103C8T6: It is a model with a high market share in the single-chip microcomputer market, and is widely used in electronic design competitions, smart cars, robots, flight control, industrial control and other fields
GD32F103C8T6: It is a domestic alternative to STM32F103C8T6. The peripheral pins are exactly the same as 3. STM32F103C8T6. It is equipped with a new generation of Cortex M3 core, with higher CPU frequency, lower power consumption and higher cost performance.
STM32F103RCT6: Contains all the pins of STM32F103C8T6 and some other peripheral pins, which can directly use the STM32 large-capacity standard library
APM32E103RET6 is a domestic alternative to STM32F103RCT6. It has a higher main frequency clock and lower operating power consumption. The built-in flash is 2 times that of RCT6, and the SRAM is 2.7 times that of RCT6. It is more cost-effective
The board is equipped with STM32 small system circuit, among which STM32F103RCT6 and APM32E103RET6 are also equipped with a 6-axis IMU on board, which can be used to obtain motion attitude
The core board leads to all 1/0 port resources
With SWD simulation debugging download interface, compared with traditional JTAG debugging, it is more reliable in high-speed mode, and the probability of download failure is smaller
Immersion gold technology, small size, reasonable and standardized layout and routing, high-quality SMD crystal oscillator, high quality

Original AMOLED Material LCD Screen and Digitizer Full Assembly for Xiaomi Mi 11 Ultra/Mi 11 Pro M2102K1G M2102K1C M2102K1AC

Before Installation Notes
Tips 1: Test before installation
When testing, do not remove any protective film or tags. Please pay attention to the problem of static electricity.
Before attempting any repair, be sure to ground yourself is an ESD (electro static discharge) strap. This will prevent static electricity from damaging the electronic components within the phone.
Ensure you wear eye protection and use caution not to cut your finger with the glass splinters.
Tips 2: Simulates testing
Screen replacement is very fragile product. We strongly suggest test before installation. Please simulates testing, which means mobile phone apart, (motherboard + LCD or screen) connected audio cable and new replacement, power on, test finished. If test OK, please install it. If it can not show, please contact us at the very first time. And please do not force it to be installed in mobile phone. We will not be responsible once the screen is installed.
Tips 3: Do not over-bend cable
