Hello guys, in this video we will use two-way ESP-NOW communication. I made these simple devices which can send short text messages to each other using the ESP-NOW protocol. The brain of the operation is the M5Stack Atom S3 development board. I needed a few additional push buttons for this task, so I designed a custom PCB. The PCB is made by PCBWay. They have been a long-time supporter in my YouTube journey. You can order these PCBs here. https://www.pcbway.com/project/shareproject/Mini_ESP32_Comunicactors_46e3a05a.html
