It's logical to just connect PHY to Ethernet switch using RJ45 Cat cable, but for real schematic you will want to use optimized solution without additional isolation transformer.
Tiny ESP32-C3 development board has USB support for serial communication, but it's not work in Platformio without by default. Here is simple solution to fix ESP32-C3 with Platformio.
DC-DC Converters, Buck-Boost, Low Power Consumption
Severity:
🟥 High
Resolution:
📟 Hardware
Description:
When you have battery powered device with low power consumption the device current during standby should be as small as possible, so in this article you will see how important to have low quiescent current of DC-DC converter.
Voltage Monitoring, Battery Charge Measurement, Low Power Consumption
Severity:
🟨 Low
Resolution:
📟 Hardware
Description:
When you have battery powered device with low power consumption during standby the device current should be as small as possible, so voltage divider from battery should be controlled and be enabled only during ADC measurement.
Fixing incorrect predefined XTAL (onboard crystal) frequency, that cause incorrect frequency of output PWM signal and rubbish charactersin debug terminal.
