Pressure measuring and control-Board: common questions
What microcontroller does the Pressure measuring and control-Board use?
The Pressure measuring and control-Board is built around the ESP-12E, from the ESP8266 family.
How big is the Pressure measuring and control-Board?
The Pressure measuring and control-Board measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pressure measuring and control-Board?
125 components, from 45 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pressure measuring and control-Board design files?
From the Mohamed-U3/Pressure-measuring-and-control-Board repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Pressure measuring and control-Board design in my own project?
Yes, under the terms of its MIT license, which Mohamed-U3 chose for the repository.
Can I test firmware for the Pressure measuring and control-Board 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.
