 =============================
 
 This example sketch can be used to measure 10BASE-T1S network performance using this software stack. The required hardware is a Arduino [Nano 33 IoT](https://store.arduino.cc/products/arduino-nano-33-iot) and a Mikroe [2-Wire ETH](https://www.mikroe.com/two-wire-eth-click) click board.
