EmbeddedCreations posted an update on his controller board for the 16×32 and 32×32 RGB LED Matrix displays:
The board looks significantly better with the Teensy soldered directly, instead of with the female headers, but I want to keep the option for people who want to remove their $20 Teensy board to use with another project. I plan to ship the kit with connectors for all the above options.
I made some revisions to the board, significant ones are listed below:
- Replaced 3.5mm terminal block with 5.0mm terminal block that can accept larger gauge wire that may be required depending on the display power cable
- Adjusted shrouded header to fit properly on the board
- Added 3.0mm mounting hole to corner of board
- Removed capacitor – testing showed it wasn’t necessary to provide a clean power supply to the Teensy
