About the Board withoutEncoder prev

Board withoutEncoder prev is an open source ESP8266 PCB design by DaniMzT, published on GitHub. It is a 2-layer board measuring 90 × 88.5 mm, with 37 components from 21 distinct parts.

Its main chip is the NodeMCU_1.0_(ESP-12E), from the ESP8266 family. Other key parts include the LM3940IT-3.3, LM2575-5.0BT, LP324N and ADS1115_ADC_Module. By type, the board carries 12 resistors, 8 connectors, 4 ICs, 4 diodes, 4 capacitors and 3 transistors.

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

From the project

Monitoring sensors of an automated door (it can be extended to generic systems). University project

A NodeMCU is the main controller, acquiring the sensors data and sending the processed data via WiFi to a database (with a PHP file as a bridge). There is an Arduino UNO for the acquisition of position, speed (both acquired with a home-made encoder: 2 micro photosensors,emitting to and receiving from a zebra band on the door) and limit switch activations (for door cycles). The communication between NodeMCU and Arduino UNO is via SoftwareSerial --> not very reliable, it is the main issue to be fixed. Database and website: based on Bitnami WAMP (package for Windows, Apache, MySQL and PHP)

Board withoutEncoder prev: common questions

What microcontroller does the Board withoutEncoder prev use?

The Board withoutEncoder prev is built around the NodeMCU_1.0_(ESP-12E), from the ESP8266 family.

How big is the Board withoutEncoder prev?

The Board withoutEncoder prev measures 90 × 88.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Board withoutEncoder prev?

37 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the Board withoutEncoder prev design files?

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

Can I use the Board withoutEncoder prev design in my own project?

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

Can I test firmware for the Board withoutEncoder prev 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.
