When I went to use esp12 and esp07, and the first problem was how to put it on the breadboard, luckily I found an adapter developed by tweeto, and that was what I needed, but I would like to make it easier to use, so I redesigned it smaller and added some labels to identify the pins, than I create a PCB to use It as programming board.
ESP8266, a little guide on how to use this low cost but powerful microcontroller with WIFI integrated.
Pinout, specifications and IDE configuration to start and programming your esp-12 and esp-07 variants.
esp-07 high resolution pinout and specs
esp-12 high resolution pinout and specs
WeMos D1 mini high resolution draw of pinout and specs
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 ESP32 DEV KIT v1 shield created for this device.
The ESP32 has enough resources to be able to use a FAT system which is certainly more expensive in terms of resources, but which offers large dimensions and few limitations, as well as compatibility with various devices.
LittleFS was recently added and focuses on higher performance and directory support, but has a higher resource consumption and occupancy per file, although not by default for esp32 it should be remembered that it takes up less resources than FatFS.
When you use a microcontroller an important features is store data, for logging or setting, for a web server or to show image. The better solution is an SD card, because It’s simple, small and low power device.
Now we are going to look how to connect and use with standard SD library with esp32.
ESP32 has the ability to take advantage of many power saving modes, there are also many wake up sources, some are specific for light sleep and in this article we will focus on UART and GPIO wake up.
