What boards using the ACS712 are built for
ACS712: common questions
Where can I find a ACS712 reference design?
Each of the 4 boards on this page is a real design using the ACS712. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the ACS712 use?
Most are built on STM32 (2) and AVR/Arduino (1).
How big is a typical board using the ACS712?
The median is 78.4 × 64.8 mm, and 25% are two-layer designs.
What is the most popular open source board using the ACS712?
By GitHub stars, To220 powerstage by rene-dev, with 979 stars.
Can I simulate one of these boards using the ACS712 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
