This directory holds several Kicad5 pcbs:

- pcbv4.pro --> main neOSensor board (esp8266 version) - pcbv4-temp.pro --> addon board featuring a temperature sensor - neOSensorV4_panel --> neOSensors panelized ;)

Note: we get inspiration from Arduino MKR1300 schematic for power supply

Pcbv4: common questions

What microcontroller does the Pcbv4 use?

The Pcbv4 is built around the ESP-12F-nospi, from the ESP8266 family.

How big is the Pcbv4 PCB?

The Pcbv4 measures 49 × 35.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcbv4?

46 components, from 33 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 Pcbv4 design files?

From the fthiebolt/neOCampus-arduino repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Pcbv4 design in my own project?

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

Can I test firmware for the Pcbv4 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.
