Electronic, 3D printing and embedded programming
We have already addressed the topic of remote wireless programming via Bluetooth of an Arduino UNO in our previous article titled “Arduino Remote/wireless Programming” however, thanks to the feedback and questions from our readers, we have decided to delve even deeper into this subject, exploring the possibilities that WiFi connectivity offers.
This integration involves connecting the LAN8720 Ethernet module with the ESP32 microcontroller to enable wired network connectivity. The process includes configuring the ESP32 to recognize and communicate through the LAN8720 module, ensuring compatibility with both plain text (HTTP) and encrypted (HTTPS) SSL data transmissions.
To enhance the ease of use for complex modules in electronics, I’m going to show my 3D-printed adapter for the EByte RF E70 module. This design, following the footsteps of my previous projects for the ESP12 and ESP32, focuses on making the E70 module breadboard-friendly for straightforward initial configuration using a PC USB.
