Front display
About the Front display PCB
Front display is an open source ESP8266 PCB design by slomkowski, published on GitHub under the MIT license. It is a 2-layer board measuring 201.9 × 54.6 mm, with 57 components from 27 distinct parts.
Its main chip is the ESP-12E, from the ESP8266 family. Other key parts include the ATMEGA88A-A, TD62C950RF, LM2596 and LM1117-3.3. By type, the board carries 18 capacitors, 14 resistors, 8 connectors, 7 diodes, 6 ICs and 1 transistor.
It belongs with the displays & leds designs in this gallery.

Front display: common questions
What microcontroller does the Front display use?
The Front display is built around the ESP-12E, from the ESP8266 family.
How big is the Front display PCB?
The Front display measures 201.9 × 54.6 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Front display?
57 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Front display design files?
From the slomkowski/octoglow repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Front display design in my own project?
Yes, under the terms of its MIT license, which slomkowski chose for the repository.
Can I test firmware for the Front display 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.
