Design and production based on lithium battery charger_with schematic diagram and PCB

Since my four-wheel drive robot is powered by a 16.5V lithium battery, and there is no charger for this battery on the market, I am very confused about charging it. In desperation, we designed a portable and simple lithium battery charger. Solve the trouble of charging. The charger can output an adjustable charging current of 100mA-1A. The input voltage is VIN>18V, and it can be charged with the 19V voltage on the laptop. Charging time is generally determined according to the size of the charging output current.

Evaluation Module (EM) Adapter

This BoosterPack package contains an "EM Adapter BoosterPack". The purpose of this EM adapter board is to provide an easy-to-use bridge between any TI MCU LaunchPad and various TI RF Evaluation Modules (EMs), such as the CCxxxx Low Power RF Evaluation Modules. No specific software is provided, so it is the user's responsibility to write the appropriate code to interface between the MCU and the RF device.

Source program based on 51 microcontroller multifunctional smart desk lamp (with clock, posture correction, display temperature and brightness)

Function description: 1. After power on, the LED light lights up, which means that the current light is in automatic control mode; 2. You can switch back and forth between automatic and manual modes through button K5; 3. In manual mode, buttons K2, K3, and K4 correspond to A light brightness; (unavailable when k1 is pressed) 4. In automatic mode, it must first detect someone before automatically controlling the brightness, otherwise the desk lamp will go out. You can block the light of the photoresistor, or use a flashlight to illuminate the photoresistor to simulate changes in lighting, so that you can see that the brightness of the desk lamp will change as the light intensity in the environment changes. The effect is that the weaker the light, the brighter the desk lamp. . If the human body sensor cannot detect anyone for 1 minute, the desk lamp will automatically turn off. (The photoresistor is behind the USB lamp); 5. Whether it is automatic mode or manual mode, the brightness is divided into 10 levels, and 0-9 is displayed on the LCD; 6. Set date and time: Press K1 (setting ) key, the cursor will flash at the displayed year position, indicating that the year can be adjusted at this time. If you need to adjust the year, press K3 (plus) and K4 (minus) to adjust the year. Then press the K2 (move) key, and the cursor will flash when the month position is displayed. The month can be adjusted in the same way. Press the K2 key again to set the day, hour, minute, and second respectively. 7. When approaching the ultrasonic wave, the buzzer will alarm.

WVGA Digital Video Serializer/Deserializer Reference Design with OpenLDI Interface for Automotive TFT LCD Displays

The TIDA-00136 reference design is a high-speed serial video interface that allows remote automotive WVGA TFT LCD displays using the OpenLDI (LVDS) interface to be connected to a video processing system. This design uses TI's FPD-Link II SerDes technology to transmit uncompressed video data over shielded twisted pair or coaxial cable. Examples of applications include rear-seat entertainment systems, automotive instrument clusters and head unit displays. This design combines the DS99R421Q1-EVK and DS90UR124-Q1 boards to form the solution.

22W MP-A11 single coil wireless charger

Provides +5V and +3.3V power to portable devices from USB port

A portable device using the circuit of Figure 1 derives power from the USB bus. The MAX1811 uses USB power charges a lithium-ion (Li+) battery at, USB compatible, 100mA or 500mA rates. Battery power is then stepped up with the MAX1797 to create the 5V supply rail. The 5V supply rail is then stepped down with the MAX1837 to create the 3.3V supply rail. The circuit includes a low battery shutdown to protect the Li+ battery and offers a convenient charging LED.
