To use this tool:

• You need an ESL Blaster (get one at furrtek.org) or build your own. ESL BLASTER Github page
• Connect to the USB device first by pressing "Connect ESL Blaster"
• Dithering is recommended. Try using dithermark.com for best results. Make sure to use exact HEX color codes mentioned below.
• Black(#000000), white(#FFFFFF), and red(#FF0000) hex color codes depending on your ESL.
• If image uploaded isn't exactly black/white or black/white/red, the ESL may not display the image properly.
• Enter a valid 17-character ESL barcode. You can use this to confirm the exact resolution of the ESL panel for the image you plan to use. There is NO auto scaling for images too big to transmit.
• Click Send Image to transmit.
