CC Table - CW32

Overview

This document describes
the use of an LDO to power a microcontroller
, an INA226 as the voltage and current acquisition chip,
and an OLED screen for display.

Issues and subsequent optimizations
: 1. Using an LDO for power supply can easily cause system restarts when the USB-B voltage changes; a DC-DC converter is planned for the next version.
2. There was a bug in the OLED screen circuitry (now fixed).
3. A resistor divider network using the CW32's built-in ADC has been added for functional verification.
4. The overall current flowing through the board is relatively low; the power supply issue for the Type-C port still needs to be addressed.
5. Reserved buttons have been removed.

How to Improve Efficiency of Flyback Power Supply
I recently made a flyback power supply, I made a flyback transformer by myself, and used PWM to adjust the duty cycle to control the output. But I found that the efficiency is very low. I hope experie
