What is KidsBlock Link?
KidsBlock Link is a small background service running on your computer. It acts as a 'bridge' that allows the web-based KidsBlock IDE to communicate with your hardware board via USB serial.
Traditional desktop software requires downloading hundreds of MB. KidsBlock Link is tiny, runs silently in the background, and lets you enjoy the full graphical programming experience right in your browser.
Whether you're controlling an Arduino LED in real time or uploading a program to ESP32, KidsBlock Link makes it all happen in the browser.

USB Serial Communication
Link monitors local serial ports and relays hardware data to the browser in real time
Real-time Two-way Communication
Supports both real-time control mode and program upload mode for different scenarios

Important Notes
- 1
Before first use, make sure the USB driver for your hardware (e.g. CH340 driver) is installed, otherwise your computer may not recognize the board.
- 2
KidsBlock Link must remain running while using the online IDE. If you close Link, the browser cannot connect to hardware.
- 3
We recommend using Chrome or Edge for the best compatibility and performance.
- 4
If you encounter connection issues, try restarting KidsBlock Link, or check that your USB cable supports data transfer (some charging-only cables don't work).
