StroomMeterACS712: common questions

What microcontroller does the StroomMeterACS712 use?

The StroomMeterACS712 is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the StroomMeterACS712 PCB?

The StroomMeterACS712 measures 101.9 × 38.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the StroomMeterACS712?

18 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the StroomMeterACS712 design files?

From the pappavis/StroomMeterACS712 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the StroomMeterACS712 design in my own project?

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

Can I test firmware for the StroomMeterACS712 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
