|
||||
- RGB Matrix Bonnet / HAT
|
||||
- Adafruit RGB Matrix Bonnet/HAT that only supports one "chain" of horizontally connected displays : https://www.adafruit.com/product/3211

|
||||
- Seengreat Matrix adapter board for single chain LED Matrix: https://amzn.to/3KsnT3j (use "regular" as hardware mapping)
|
||||
- LED Matrix panels (2x in a chain is recommended)
|
||||

|
||||
## Optional but recommended mod for Adafruit RGB Matrix Bonnet
|
||||
- By soldering a jumper between pins 4 and 18, you can run a specialized command for polling the matrix display. This provides better brightness, less flicker, and better color.
