The L298N driver board is a commonly used motor drive module.
Here are some of its main features and introduction: Features: 1. High power drive capability: Capable of driving DC motors and other devices, with a certain power output capability. 2. Four-way control: Can independently control the operation of four motors simultaneously. 3. Multiple control modes: Supports speed adjustment, forward and reverse rotation, and other operations of the motor by inputting different signals.
4. PWM speed control: Motor speed can be adjusted by inputting control signals. Working principle: By receiving external control signals, such as signals from a microcontroller or other controllers, it converts them into the drive current and voltage required by the motor, thereby achieving precise control of the motor. Application scenarios: Widely used in projects requiring motor drive, such as robots, cars, and smart homes. When using the L298N driver board, it is necessary to pay attention to the proper connection of the power supply, motor, and control signals, and to perform corresponding programming or circuit design according to specific needs to achieve effective control and good operation of the motor.

An adapter board made using FPC to drive MIPI screens.
This is an adapter board made using FPC to drive MIPI screens. Currently, it's compatible with the 5.0-inch XH8379A MIPI screen
and also supports the NT35516 screen, as the definitions and interfaces are completely identical. For touch: the FT5436
D133 supports RGB, LVDS, and MIPI. Therefore, an adapter board was made to extract the MIPI signal from the original development board's RGB interface
and connect it to the phone screen interface. The backlight uses the original RGB screen's backlight.
Note that the backlight driver current must be checked, otherwise the backlight will burn out, and the backlight driver may also be damaged.
Using FPC for the connection eliminates the hassle of external ribbon cables and connectors, allowing for reinforcement where needed.

Touch fan
The small fan, based on a touch chip, supports three speed settings from 3 to 9V.
Finished Touch Fan Image
and Shell Display
; Fan Introduction:
This fan uses the RH6015C as the touch switch. The motor driver chip employs multi-level LED display technology to indicate the battery level. The touch sensitivity is adjustable by the user, ranging from 0-50Pf; the lower the value, the faster the response. This fan has been verified and its production cost is approximately 30 per month.

7.5-inch desktop e-ink screen development board
Desktop 7.5-inch e-ink screen development board & 7.5-inch e-ink screen weather station high-resolution version
The original project address is reproduced, and the PCB has been redesigned to fit this shell: https://gitee.com/corogoo/epaper-7.5-weather-station-plus. This
7.5-inch e-paper weather station high-resolution version
can be used as a development board and can utilize other people's projects.
When used as a development board, this screen (HINK-E075A41-A0) can use the Waveshare 7.5-inch e-Paper electronic ink screen module (red 800×480 pixels) with SPI communication (waveshare.net) or the Good-Display driver example: 7.5-inch three-color e-paper supports 1.3s black and white partial refresh 800x480 resolution GDEY075Z08_Electronic Paper - Dalian Good-Display Electronics Co., Ltd. (good-display.cn) program to drive this screen.
This desktop 7.5-inch e-paper development board has been verified to drive Good-Display 7.5-inch three-color and two-color e-paper screens. It has a built-in battery and charger, and four reserved touch buttons. It has been verified to be usable.
Note: (The custom version is a template drawn based on the original price tag PCB, not a PCB. The adapted version is an enlarged version of the original PCB. If it is a price tag, the outer shell needs to be modified.)
