SparkFun 7-Segment Serial Display - Kelly Green
Discontinued
The SparkFun 7-Segment Serial Display combines a 4-digit 7-segment display with an ATmega328 microcontroller, letting you control every segment using just a few serial lines. Choose from three communication interfaces: serial TTL, SPI, or I²C — and even program the on-board ATmega328 directly via the Arduino IDE using the included bootloader and FTDI header.
Power and I²C pins are positioned on the sides of the board so multiple displays can be chained together for longer digit strings. Mounting holes allow secure installation on standoffs.
