PCB WIRE LAYOUT SCHEMATIC
Transmitting tube output ground line
SC6121
The transmitting tube ground line and IC ground line should
layout separated or overstriking ground line.
The above IC only use to hint, not to specified.
Note:
* In wire layout, the power filter capacitor should near to IC.
* In wire layout, should avoid power line and ground line too long.
* Recommended infrared transmit unit and IC ground line should layout separated, or overstriking lines.
* The emitter of triode connect 1 resistor at least.
* Recommended triode use 9014.
