ESP-Sensors: common questions
What microcontroller does the ESP-Sensors use?
The ESP-Sensors is built around the ESP-12E, from the ESP8266 family.
How big is the ESP-Sensors PCB?
The ESP-Sensors measures 58.4 × 54 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ESP-Sensors?
17 components, from 13 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESP-Sensors 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 ESP-Sensors 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 ESP-Sensors 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.
