Note:
1. filtering capacitor between VDD and GND should be arranged on PCB plate as close to TM1637 chip as possible to strengthen filtering effect. 2. 100pF capacitor connected to the DIO, CLK communication port pull-up and pull-down can reduce interference to radio communications port. 3. Since blue-ray nixie tube break over step-down voltage is 3V, TM1637 power supply should be 5V.
