NodeMCU-Metriful: common questions
What microcontroller does the NodeMCU-Metriful use?
The NodeMCU-Metriful is built around the NodeMCU 1.0 (ESP-12E), from the ESP8266 family.
How big is the NodeMCU-Metriful PCB?
The NodeMCU-Metriful measures 81.7 × 57.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the NodeMCU-Metriful?
21 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the NodeMCU-Metriful design files?
From the axello/kicad repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the NodeMCU-Metriful design in my own project?
The repository has no license, so all rights stay with axello. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the NodeMCU-Metriful 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.
