Create a Wireless NTP Server with ESP32 and GNSS (Wi-Fi & Ethernet)
Did you ever wish your projects had access to precise time — without relying on the internet?
In video #503, we built a solid GPS-based time server using a Raspberry Pi. It worked, but let’s be honest — it was bulky.
Now imagine: The same functionality, but packed into a tiny ESP32 Super Mini board.
Today, we’ll build a precision NTP server that easily fits in your palm — and along the way, we’ll uncover why some “high quality” GPS modules on AliExpress are suspiciously cheap. Intrigued? Let’s dive in.
