DC LOAD V01
About the DC LOAD V01 PCB
DC LOAD V01 is an open source AVR/Arduino PCB design by jmos1, published on GitHub. It is a 2-layer board measuring 134.1 × 95.3 mm, with 23 components from 18 distinct parts.
Its main chip is the Arduino_Nano_v3.x, from the AVR/Arduino family. Other key parts include the LM358, 74HC14 and ADS1115IDGS. By type, the board carries 7 resistors, 3 connectors, 3 capacitors, 2 ICs, 2 modules and 2 transistors.
From the project
The BOM, schematic PDF, and gerber files are all accessible in the 'Outputs/' folder. Other project files are not included because they add clutter and can be generated from the project itself in KiCad. Thanks.

DC LOAD V01: common questions
What microcontroller does the DC LOAD V01 use?
The DC LOAD V01 is built around the Arduino_Nano_v3.x, from the AVR/Arduino family.
How big is the DC LOAD V01 PCB?
The DC LOAD V01 measures 134.1 × 95.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the DC LOAD V01?
23 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the DC LOAD V01 design files?
From the jmos1/DC_LOAD_V01 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the DC LOAD V01 design in my own project?
The repository has no license, so all rights stay with jmos1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the DC LOAD V01 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
