IP5306 module

A minimalist, budget-friendly power bank solution based on IP5306

This is
a small gadget built using the IP5306_CK. It can directly charge a single 3.7V~4.2V lithium battery using 5V USB power, or output 5V 2A. Both input and output use USB-C ports (I recently got a bunch of USB-C ports from LCSC, which is ridiculously abundant).
Parameters
: Input: 5V 1.8A;
Charging current: 2.1A;
Charging cutoff voltage: 4.2V;
Output: 5V 2.4A.
Other functions: Lighting, power display (4-LED solution). A few notes : The output USB-C port
works fine when plugged into an external 5V USB power source; at least it didn't burn out. Connecting the output USB-C port to the input USB-C port via a C2C cable didn't burn out either, but it doesn't work properly (it's possible the lithium battery I'm using has too high internal resistance, acting as a protection mechanism). I used the DW03D solution instead of the DW01+ dual MMOS solution simply because I was lazy and didn't want too many chips.

Infrared tracking

Four-way infrared tracking module

Version Description
Version Name: Four-Way Tracking Module V1.1, V1.2
Release Date: 2023/11/15
I. Function Introduction
Project Introduction Video

This module has four outputs, each equipped with an indicator light to indicate its status.
There are two versions: V1.1 with a 74HC14D chip, and V1.2 without this chip.
Elegant design. The design style is based on several excellent products found online. II. Renderings


III. Functional Modules
1. Power Indicator
This is a power indicator light; the brightness can be controlled by adjusting the resistance of R1.
2. Four-Way Infrared Tracking Module
The circuit logic of these four tracking modules is the same. The essence of infrared tracking is that different colors reflect infrared light to different degrees. This module uses the TCRT5000, which consists of an infrared emitter and an infrared receiver.
Its working principle is as follows, for example: When the infrared emitter encounters a black line, the reflected light is weak and cannot turn on the infrared receiver, so IN1 is high and the indicator light is off. When it encounters a white line, the reflected light is strong and can turn on the receiver, so IN1 is low and the indicator light is on. We can determine the color of the detected line based on the voltage level of the INx pin, thus achieving line tracking.

Note: Version V1.2 seems to be able to output analog signals, which can be analyzed in the description of the module's circuit diagram on Taobao. It's similar to the voltage divider form of a series photoresistor. This needs further testing and will be explained in the version description after testing.
3. Four Tracking Indicator Lights
These four lights are indicator lights for the four-way tracking module, used to indicate the working status for easy observation and debugging.
4. Screw Holes
Four screw holes are reserved for easy installation.
IV. Remarks

This project will be continuously improved and updated.
