Precautions for welding installation, follow the following steps: 1. When welding components on the front panel, follow the principle from low to high, that is, weld low components first, such as capacitors, resistors, diodes, etc. 2. Weld the IC socket and terminal blocks, and finally weld the power socket and adjustable potentiometer. 3. Use diagonal pliers on the back to cut the pins as short as possible Debugging steps: 1. After the XR2206 IC is soldered, pay attention to the direction of the IC. Insertion may damage the chip! 2. Check whether the IC is reversed. If so, please correct it in time. 3. Plug in the power supply. The power supply is 5.5*2.1 port, and the inside and outside are negative. Suitable for 9-12V power supply voltage. Waveforms may be unstable above 12V Usage steps 1. Plug in the J1 jumper cap, and the SIN/TRI blue terminal outputs a sine (note that only one of J1 and J2 can be plugged in) 2. Plug in the J2 jumper cap, and the SIN/TRI blue terminal outputs a triangle (note that only one of J1 and J2 can be plugged in) 3. SQU blue terminal output pulse 4. AMP: Sine and triangle amplitude adjustment 5. FINE: Frequency fine adjustment 6. Coarse adjustment: coarse adjustment frequency
