About the Environment monitor-1.4 PCB

Environment monitor-1.4 is an open source ESP8266 PCB design by theopensourcerer, published on GitHub. It is a 2-layer board measuring 31.1 × 43.2 mm, with 14 components from 11 distinct parts.

Its main chip is the ESP-12F, from the ESP8266 family. Other key parts include the MCP1700T. By type, the board carries 4 resistors, 3 connectors, 3 switches, 2 ICs and 2 capacitors.

It belongs with the sensors and iot & wireless designs in this gallery.

From the project

ESP8266/BME280 Environment Monitor Project

The project consists of three parts: the case to hold the monitor, the hardware (PCB and Sensor(s) etc.) and the software.

The case is designed in OpenSCAD and is suitable for printing on a 3D Printer. I am very pleased with the results of the design. Please feel free to use and improve - within the terms of the license of course.

The Schematic and PCB are designed in KiCAD. The board has not yet been fully tested. In fact the board has several flaws, some of which do not seem to be problematic, but one that caused me a long headache. The pin called CHPD on my board needed to be pulled…

Environment monitor-1.4: common questions

What microcontroller does the Environment monitor-1.4 use?

The Environment monitor-1.4 is built around the ESP-12F, from the ESP8266 family.

How big is the Environment monitor-1.4 PCB?

The Environment monitor-1.4 measures 31.1 × 43.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Environment monitor-1.4?

14 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Environment monitor-1.4 design files?

From the theopensourcerer/esp8266_envmonitor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Environment monitor-1.4 design in my own project?

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

Can I test firmware for the Environment monitor-1.4 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.
