FlatCAM is a program for preparing CNC jobs for making PCBs on a CNC router. Among other things, it can take a Gerber file generated by your favorite PCB CAD program, and create G-Code for Isolation routing.
Here we are going to create gcode and show the milling process.

Here we are going to remove copper islands.
Library to use i2c pcf8574 IC with arduino, esp8266 and esp32.
This IC can control (until 8) digital devices like button or led with 2 only pins.
Here I explain the manage of multiple rotary encoder.

Here tha isolation of traces.

Here an introduction, how to install and import files.
For static information (Web pages for examples), that not change frequently, esp8266 or esp32 have internal SPIFFS (SPI Flash File System) and you can upload data via Arduino IDE as explained in the article “WeMos D1 mini (esp8266), integrated SPIFFS Filesystem” but for fast operation and future support It’s usefully use FTP.
When you create a datalogging It’s important to structure your data, sometime a good solution can be JSON format.
Here a tutorial on E32 LoRa (Long Range) device very cheap and very long range (from 3Km to 8Km).
In this chapter we are going to wake on radio the LoRa E32 and microcontroller and we show the WeMos D1 mini shield created for this device.
