I wanted to make a programmed walkie talkie for a long time and I’ve finally made it, and if you want to also replicate this project, download my GERBER files from below for free as always. Go to PCBWAY.com and click the quote now button. Here we add the size of my PCB and also select a color. I’ve selected the black one. Save to cart and on the next page upload the GERBER files you’ve downloaded and make the order. For only 5 dollars you can get 10 great PCBs for your prototypes and cool projects. In a few days I received my PCBs and I was ready for my walkie talkie.

My PCB has a small vibrating motor and RGB LED for notifications, it could have single channel or broadcast mode, it has an OLED display to show any value you want and with an ESP32, you can always go further and involve IOT or any other internet related plugin. Imagine a walkie talkie with internet.
