AlphaNum R Click is a simple solution for adding 14-segment alphanumeric display to your device. The board carries two TLC5926 16-bit Constant-Current LED sink Drivers as well as a dual character red LED 14-segment display (with two additional segments for commas). AlphaNum R Click communicates with the target board through mikroBUS RST, CS, SCK, MISO, MOSI, PWM and INT pins (marked here as LE2, LE1, CLK, DOUT, DIN, NUMSEL and NUMSEL# respectively). The board is designed to use either a 3.3V or 5V power supply.
