Product Introduction:
This product is a multi-mode serial port module. By setting the module according to the setting table through the dial switch on the board, different modes can be converted and selected.
There are a total of 6 modes, namely USB to TTL mode, USB to 232 mode, USB to 485 mode, TTL to 232 mode, TTL to 485 mode, and 232 to 485 mode.

Specification:
Input voltage: DC3.3V-5.5V
Support: for Win10, Win8, Win7, WinXp, Win2K, WinCE, Linux, Mac
Adopting CP2102 as the core chip
Power output: This module can provide power to the microcontroller system for easy debugging. 5V-500A
Or 3.3W-100mA.
Overcurrent protection: board mounted self recovery fuse, even if the positive and negative poles are short circuited, it will not damage the circuit board
Or a computer. If a short circuit occurs or the current exceeds 500A, the fuse will automatically break
On, when the circuit returns to a non short circuit state, the fuse returns to normal.
Transceiver indicator light: When there is data on the sending or receiving line of the serial port, the transceiver indicator light on the board will light up for easy debugging.
TL level interface: It can directly connect to microcontrollers or other embedded devices, such as 51, STC, AVR, AFM, FPGA, etc., without conversion.
RS232 level interface: Connect to a computer or S232 level serial port device.
RS485 level interface: automatic transmission control, no need for transmission control line, default receiving status, change to sending status when there is data on the sending line.
Four levels of free mutual conversion: circuit design, USB, TTL, RS232, RS485 free mutual conversion, physical switching achieved through switches, convenient and reliable, without interference.
High speed communication: The baud rate can reach 2Mbps.
Product size: 55.00×19.00×7.00mm
Product size: 2.17×0.75×0.28inch
Origin (country or region): Chinese Mainland (Origin)
Type: Module
New and old: new
