Electronic, 3D printing and embedded programming
Here is a tutorial on library of new Ebyte LoRa (Long Range) devices. E220 device based on LLCC68 very cheap and long-range (from 4Km to 10Km) with less power than sx1268.
Start with specs and basic use.
In this tutorial I try to explain how IoT core can be used to connect our devices to AWS services.
Now we look at the esp32 connection steps.
In this tutorial I explain how the IoT core, through AWS services, can communicate with our devices. In particular, let’s see the use of the MQTT protocol.
Now let’s go through the esp8266 connection steps.
Arduino NANO 33 IoT high resolution pinout and specs
To help with fast prototyping, I’m going to create a set of shields for the WeMos D1 mini. The shield of this article manages the EBYTE LoRa device (E22, E32 and E220) with HardwareSerial, already exists a variant with SoftwareSerial.
In this article, we’ll understand the security system used by Amazon, with a certificate, to connect our device via MQTT.
To help fast prototyping I’m going to create a set of shield for WeMos D1 mini, the shield manage a 3.3v relay with configurable pins
NodeMCU v3 high resolution pinout and specs
For fast prototyping, I will create a set of shields for the WeMos D1 mini; the first is a service board with integrated pcf8574 IC, an encoder, and five other pins to use as input or output.
After carrying out all the calibrations, all that remains is milling our piece. If the whole process is successful, I expect an excellent final product.
