A portable miniature intelligent electric SMT solder paste dispensing pen supports quantitative extrusion and suction control of dispensing syringe container and displays various parameters through 0.91-inch OLED screen.

The intelligent tin point pen is based on the ESP32 C3 chip N20 deceleration motor to drive the push rod to realize automatic extrusion and suction functions. Through the MCU6050 to detect the motion posture and collect the rotation signal of the Hall encoder on the N20 motor to realize intelligent control and quantitative control of extrusion and suction, and pass 0.91 inches OLED screen displays various parameters, supports TYPE-C to directly download and burn programs and charge lithium batteries, etc.
