Show numeric information with this blue four-digit serial display. An ATmega328 manages individual segments and accepts serial TTL, SPI or I2C control, reducing direct segment wiring. The installed Arduino bootloader and FTDI header also provide a programming route for experiments that run suitable code on the display’s own microcontroller.
