QuadClock PCB – An ESP32-S3 multi-display clock controller for DIY enthusiasts
The QuadClock PCB is an ESP32-S3-powered multi-display clock controller designed to serve as a foundation for creating a four-TFT-display clock. It supports up to four 1.69-inch rectangular TFT displays (240×280) or four 1.28” round displays (240×240). It manages essential functions such as driving the displays and maintaining precise time, allowing you to focus on crafting a unique enclosure or integrating additional features. It is open-source and is powered by the ESP32-WROOM-1 module with up to 16MB flash and 2MB PSRAM. It supports independent brightness control for each mounted display via four MOSFETs and includes an onboard real-time clock with a backup battery for accurate timekeeping. The QuadClock PCB is designed for enthusiasts and makers interested in creating multi-display clock projects. It can also be used for stock tickers, weather displays, and smart home dashboards.
