LED display 4 digits + TM1637 controller - Arduino
Functional description of the leads
DIO Serial data input/output, pin 17, serial data input/output, input data is written to SCLK high level, each byte received during transmission, generates ACK signal at the ninth clock bar.
CLK Clock input, pin 18, data is rewritten on the rising edge of the clock signal
K1 ~ K2 Key-scan data input, pin 19-20, data entered on the pins will be read (latched) at the end of the display period
SG1 ~ SG8 output (segment), pin 2-9, segment output (also used for keyboard scanning) type N, open drain output
GRID6 ~ GRID1 Output(grid), pin 10-15, display anode control output, P-type, open drain output
VDD Logic power, pin 16, 5V ± 10%
GND Logic ground, pin 1, connected systematically
