Thông số kỹ thuật: - CP2102 core chip: CP2102 USB to serial chip is the best quality, the most stable, low-cost performance far exceeds similar chips, such as PL2303, FT232, CH341 and so on. High-speed, reliable and stable is capable of leading sales CP2102 USB-to-serial module important reasons.
- Ultra-small size: The circuit board is only 3.1cm X 1.8cm. Ultra-small size, lack of a U disk size, only with a USB port width, even on those two USB ports from the very tight laptops can easily be placed side by side two.
- 3.3V and + 5V Compatible: This product perfectly supports 3.3V. Now a lot of high-end microcontroller, such as ARM, STM32, DSP, adopted 3.3V. Other modules are only compatible 5V level, they do not have the 3.3V output.
- Power output: can be supplied by the module to the microcontroller system to facilitate debugging. 5V-500mA or 3.3V-100mA.
- Overcurrent protection: resettable fuse onboard, even if the positive and negative short-circuit will not damage the circuit board or a computer. If there is a short circuit or current exceeds 500mA, the fuse will automatically disconnect, to be a non-short-circuited fuse circuit recovery back to normal. Effectively protect the security of your computer.
- Transceivers LED: When the serial transmission line or receive online data, send and receive LED panel light, easy debugging.
- TTL level interface: can be directly connected microcontroller or other embedded devices, such as 51, STC, AVR, ARM, FPGA, etc., without conversion.
- RS232 level interface: Rs232 level connect a computer or serial device.
- RS485 level interface: automatic transceiver control without transceiver control line, default reception state, the transmission line to transmit state data.
- Four levels of freedom system conversion: a unique circuit design, USB, TTL, RS232, RS485 free conversion, switched through the switch to achieve physical, convenient and reliable, without interference.
- High-speed communications: Baud rate up to 2Mbps.
- DTR, RTS signal: serial module leads the DTR, RTS signal versatile, support MSP430 MCU BSL downloads.
- SMT machines, industrial-grade chips: This module uses the whole machine patch process technology, quality and cheap manual patch welded qualitative difference, stable and reliable performance guarantee.
Compare similar products on the market, you will find some others function, we have, others do not, we have. Features: 3.3V output, overcurrent protection, 232 to 485, automatic transceiver control, industrial grade components and so on.
Price decision quality, materials and workmanship determine prices, industrial grade components are genuine shop use, parents who do not, and the market price of common modules and shopkeepers bargain.
Do you often USB to serial stability of concerns? How often is two days and it broke it? Not good goods cheaper, I believe we all understand this truth, if you buy a product, difficult to use, or single function, instead of wasting your money and time. Our module uses the industry's easiest to use CP2102 chip, reliable quality. Therefore, the interface chip SMD components are imported in Maxim (Maxim) company industrial-grade chips: Max485ESA, pay attention to the suffix, civilian level is (CSA, CSE), 232 chip SIPEX company imported industrial chip SP232EEN (Note suffix ), Quality Assurance!
Our modules SMD components used in all machining, in order to ensure quality, in strict accordance with industry procedures, the first steel mesh, then using a large reflow machine welded. Weld eliminate caused due to hand soldering, desoldering, weld and other quality problems. I believe that sentence, a penny stock, we need to do is market the best quality multifunction USB to serial module.
