About the Endev v1.1 PCB

Endev v1.1 is an open source ESP8266 PCB design by sophiayduan, published on GitHub under the MIT license. It is a 2-layer board measuring 36 × 70 mm, with 59 components from 40 distinct parts.

Its main chip is the ESP-12F, from the ESP8266 family. Other key parts include the ATMEGA328P-A, CH340N, LIS3DH, TP4057 and XC6206P332MR. By type, the board carries 17 capacitors, 16 resistors, 8 ICs, 7 diodes, 4 connectors and 3 switches.

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

From the project

3d printer monitor pcb

Features: Form factor: Fits inside the spool holder bracket Mounting: Magnets that align with the spool holder bracket Peripherals: ESP-12F (notifications over wifi/bluetooth) Accelerometer (intense vibration detection) Temp/humidity sensor Configuration switches Status LEDs

Filament Funout detection LED strip attachment

I built it as my printer is not known for its reliability, so by tracking common points of failure, I can hopefully stop the print before wasting too much filament.

The KiCad project lives in the sophiayduan/Endev-board repository on GitHub; these links point at the commit this page was built from.

Endev v1.1: common questions

What microcontroller does the Endev v1.1 use?

The Endev v1.1 is built around the ESP-12F, from the ESP8266 family.

How big is the Endev v1.1 PCB?

The Endev v1.1 measures 36 × 70 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Endev v1.1?

59 components, from 40 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Endev v1.1 design files?

From the sophiayduan/Endev-board repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Endev v1.1 design in my own project?

Yes, under the terms of its MIT license, which sophiayduan chose for the repository.

Can I test firmware for the Endev v1.1 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.
