OpenSegment Serial Display

OpenSegment
OpenSegment Serial Display (Yellow) (COM-11645)

OpenSegment is a ATmega328 based backpack for larger 7-segment displays. The ATmega receives data over digital interfaces (such as TWI, UART, SPI and buttons) and does all the PWM and upkeep of the display.

Larger 7-segment displays pull more power than a microcontroller is able to drive directly. OpenSegment has 8 PNP and 4 NPN transistors in order to drive the segments at their maximum brightness.

Features:

  • Standard FTDI connection
  • Arduino Pro Mini @ 8MHz bootloader
  • 5V functionality

This part was created in Eagle 6.3
