Nbsp; & nbsp; & nbsp; & nbsp; QR-300 STC MCU programmer, communicates with the computer through USB interface, only needs a USB cable to connect with the computer. It is equipped with a high-quality USB cable, and the lock seat of the programmer uses high-quality copper pins, which is twice as expensive as the ordinary one and is durable. This site programmer, quality assurance!
QR-300 STC programmer has the following characteristics:
1: The protection resistor is designed in the circuit, even if the chip is inserted backward, it will not burn the chip. (Everyone knows that if the chip is inserted backward in STC, the chip will burn out.)
2: The large capacitor (16V470uF) is used for power filter and energy storage, which alleviates the impact of MCU on the USB interface when power is on, and makes the USB serial chip work more stable.
3: High frequency crystal oscillator (22.1184 MHZ) is used to ensure that all chips can download at the fastest speed (115200) when writing programs, thus saving your time.
4: There is a one-button switch to switch different packages. In the DIP8, 16, 18, 20, 28 to DIP40, only one switch is needed.
The STC10 1112 series DIP14 161820 is aligned according to the figure 1 feet.
STC8 STC15 series DIP8 1618202840 is aligned on the right side of this diagram.
The STC10 1112 series DIP14 161820 is aligned according to the figure 1 feet.
STC all DIP28 singlechips are burned according to this location.
STC all DIP40 singlechips are burned according to this location.
