Climatedisplay
About the Climatedisplay PCB
Climatedisplay is an open source ESP8266 PCB design by Qeteshpony, published on GitHub under the BSD-2-Clause license. It is a 2-layer board measuring 100 × 100 mm, with 59 components from 18 distinct parts.
Its main chip is the ESP-12F, from the ESP8266 family. Other key parts include the 74AHCT1G08, AMS1117-3.3, 2281AS and MAX7219. By type, the board carries 25 ICs, 17 capacitors, 12 resistors, 2 connectors, 2 switches and 1 diode.
It belongs with the displays & leds, iot & wireless and sensors designs in this gallery.
From the project
7-Segment Display with 4 blocks of 2x4 digits
Complete overhaul of one of my earlier electronics projects! A display that is running here for years, back then made completely with THT components on a crude pcb. It shows the temperature and dew point for the room and outdoor sensors.
I learned a lot about pcb design since then and was not happy with the look of the old device so I remade the whole device in a way that keeps the general look but a lot more fancy, moving everything but the display elements to the back of the board, adding a 3d-printed frame, replacing the barrel connector with USB-C and many more little things.

Climatedisplay: common questions
What microcontroller does the Climatedisplay use?
The Climatedisplay is built around the ESP-12F, from the ESP8266 family.
How big is the Climatedisplay PCB?
The Climatedisplay measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Climatedisplay?
59 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the Climatedisplay design files?
From the Qeteshpony/climatedisplay repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Climatedisplay design in my own project?
Yes, under the terms of its BSD-2-Clause license, which Qeteshpony chose for the repository.
Can I test firmware for the Climatedisplay 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.
