Four-way speed digital tube display

Overview

1 Detect 4-channel switching signals, or detect 4-channel ADC, 0.56-inch digital tube display with alarm indicator light 2 This module is not designed well, because it can be drawn at any time during testing, the packaging design is unreasonable, and the voltage reduction is also unreasonable. Get LDO buck. 3. If the wiring is thin, it can be used alone, but the resistor selection is not reasonable. Please modify it if used.
