Hi! To receive the .bin file, please consider making a small donation: it rewards me for the long days of hard programming work 😅. Thank you so much 🙏

CYD Flasher

This browser doesn't support Web Serial. Open this page with Chrome or Edge on a computer (not Safari/Firefox).

1. .bin files

Drag your .bin files here or click to choose them
Recommended: upload only the .merged.bin file (address 0x0): it contains the bootloader, the partition table (Huge APP) and the sketch.
If you upload only the sketch file (.ino.bin, address 0x10000), the board must already have the Huge APP partition scheme. Addresses are detected from the file name and can be edited.

2. Settings

Erase the entire flash before programming (this also wipes saved settings)
The partition scheme is decided when you compile/export the sketch: it is shown here only as a reminder. For Huge APP, use the .merged.bin file exported with that scheme.

3. Flash

Waiting

    
Connect the CYD via USB and choose the port (usually “USB-SERIAL CH340” or similar). If the connection fails, hold the BOOT button while clicking the button and release it when the upload starts.
