The ENC28J60 Module is a standalone Ethernet controller with an industry-standard Serial Peripheral Interface (SPI™). It is designed to serve as an Ethernet network interface for any microcontroller equipped with SPI Communication Module.
The ESP-01 Breakout Adapter for ESP8266 serial to Wi-Fi transceiver module. Since the ESP-01 pinout is not breadboard friendly and unlabeled, this makes it inconvenient for rapid prototyping.
The ESP32-S is a wireless module based on ESP32, supports Wi-Fi and Bluetooth 4.2, with built-in 32Mbit Flash, in the SMD38 package. There are also on board PCB antenna and metal shield.
This module could modulate your voice on the FM radio wave. And anyone who has a radio device could receive it. We build everything on this module, which makes it very easy to build a tiny radio station
