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
