SeriAlpha is a small backpack for alphanumeric LEDs (16 segment, specifically). It will accept I2C/SPI communications, and control the LED display attached to it.

Project Status

Schematic/board done, BOM on file at Digikey, board sent to BatchPCB for prototype manufacturing.

Design Overview/Ideas

  • Based around the ATtiny2313
  • Individual transistors for each segment, so it will support all segments on at once and nifty things like PWMing segments
  • Built in character generator, so you can just tell the board what letter/number to display.
  • Targeting the SparkFun-sold 16segment LED displays
