About the Esp8266-temp sensor PCB

Esp8266-temp sensor is an open source ESP8266 PCB design by halicek, published on GitHub. It is a 2-layer board measuring 18.4 × 39 mm, with 16 components from 11 distinct parts.

Its main chip is the ESP-12E, from the ESP8266 family. Other key parts include the STM1061, MCP1603T-330I_OS and SHT31-DIS-B. By type, the board carries 7 resistors, 4 ICs, 3 capacitors, 1 fuse and 1 inductor.

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

From the project

Wireless IoT temp/hum sensor - ESP8266, SHT30, low voltage cut-off

Why so high voltage cut-off? It seems that around 3.0 V input regulator will not supply enough power for ESP8266 to perform well so this regulator meant for 3.3V power level seems appropriate. Please prove how wrong I am! :)

Esp8266-temp sensor: common questions

What microcontroller does the Esp8266-temp sensor use?

The Esp8266-temp sensor is built around the ESP-12E, from the ESP8266 family.

How big is the Esp8266-temp sensor PCB?

The Esp8266-temp sensor measures 18.4 × 39 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp8266-temp sensor?

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

Where can I download the Esp8266-temp sensor design files?

From the halicek/esp8266-temp-sensor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Esp8266-temp sensor design in my own project?

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

Can I test firmware for the Esp8266-temp sensor 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.
