Description

This is a DIY project aimed at providing a practical, useful and safe electronic load for people interested in electronics. While it is not be the most powerful electronic load available, it is designed to be easy to use and reliable, making it an excellent option for those looking for a DIY electronic load. We develop a HW and SW for complete integration, but you can pick up just one of them. Based in microcontroller ESP32-C3. You can find more info and firmware in my Github: https://github.com/CasamaMaker/eLoad

Features

The Electronic Load - 60W has several features that make it a practical and useful tool, including:

25Vdc maximum voltage
5A maximum current
60W power output (12V/5A, depending on cooling system)
Based in microcontroller ESP32-C3
Reverse polarity voltage protection
Thermal protection to prevent avalanche breakdown due to temperature
Overcurrent and overvoltage protection
Adjustable current, voltage and power settings by fisical selector
Switch to dis/enable load functions
Easy-to-read display for current, voltage and power monitoring
Easy-to-configure wifi ssid and psk
Live graphic on web for current, tension and power monitoring
Cooling fan output, 12Vdc/0.5A
It is powered by a typical 5V USB-C power source
