EnergyMeter: common questions
What microcontroller does the EnergyMeter use?
The EnergyMeter is built around the ESP-12F, from the ESP8266 family.
How big is the EnergyMeter PCB?
The EnergyMeter measures 94 × 82 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the EnergyMeter?
66 components, from 43 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 EnergyMeter design files?
From the jkordek1/EnergyMeter 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 EnergyMeter design in my own project?
The repository has no license, so all rights stay with jkordek1. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the EnergyMeter 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.
