Electric Load and Logger

This is an Electric Load and Logger. It can consume the power of the device and send the data to the server. The maximum power is 100W, maximum voltage is 30V, and maximum current is 10A. But, it must be used under 100W. And it can measure the voltage, current, and power consumption of the device and send the data to the InfluxDB server. You can see the data on the Dashboard.

Electricload: common questions

What microcontroller does the Electricload use?

The Electricload is built around the ESP32-S3-WROOM-1-N16R8, from the ESP32 family.

How big is the Electricload PCB?

The Electricload measures 185 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Electricload?

71 components, from 35 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Electricload design files?

From the hnz1102/electricload repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Electricload design in my own project?

The repository has no license, so all rights stay with hnz1102. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Electricload without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
