This module is a USB connector/software engineer for ESP8266 modules of sort ESP-01 or ESP-01S. It is helpfully fitted with a 2x4P 2.54mm female header to plug the ESP01. Additionally, it breaks out every one of the pins of the ESP-01 through a 2x4P 2.54mm male header, so it is exceptionally helpful for the client to troubleshoot the ESP8266.
For what reason did you make it?
The module depends on the USB-UART CP2104 which is perfect with all stages. Locally available with the ESP8266 programmed download circuit. It is exceptionally advantageous for clients to download ESP-01/01S program, redesign firmware, sequential troubleshooting, etc. It underpins loads of programming, for example, Arduino IDE, ESP8266 Flasher, and Lexin FLASH_DOWNLOAD_TOOLS. There is no compelling reason to press any catches, the WiFi module will consequently enter the download mode.
RJ45 interface adapter is a module to turn the DuPont cable interface into network cable interface (RJ45 connector). When using arduino to measure temperature and humidity, detect soil moisture and ambient light, the test location is often far away (over 2 meters) from the arduino board. In view of the general line of DuPont severe signal attenuation, you can use two RJ45 interface adapter module and a 5 m or 30 m of network cable to connect the sensor or other modules.
Note: This module is generally used in pairs.
1 x RJ45 Adapter Module
All Communication Protocol in just one module , This module will solve your problem in common communicating interface module.
USB to TTL/RS232/RS485,
TTL to RS232/RS485,
RS232 to RS485, automatic flow control, stable performance, extremely suitable for hardware engineers.
This product uses CH340T chip, which is truly compatible with USB2.0, and the baud rate is up to 256kbps
Driver download address: http://www.wch.cn/downfile/65
The DB9 header outputs the RS232 level, the second pin is the receive, the third pin is the transmit, and the fifth pin is the GND.
The blue terminal is the RS485 output interface
S1 is a USB to 232 and 485 selector switch. The left side is the USB to RS232 function, and the right side is the USB to RS485 function.
S2 to the left is USB to 232/485/TTL, and TTL to 232/485
S2 dials to the right is 232 to 485, when using the 232 to 485 function, the J1 and J2 connection jumpers should be removed
J1 is the TTL level and 5V power supply that USB turns out. From left to right, this is 3.3V,5V, TxD, RxD, GND.
J2 is the TTL end interface of TTL to RS 232/485. From left to right, this is TxD, RxD, GND. Note that when using TTL to RS232 function, you need to add 5V power to this board, or take power through computer USB
When using USB to RS232/485 function, plug in the RxD and TxD jumpers of J1 and J2; when using USB to TTL or TTL to RS232 function, remove the RxD and TxD jumpers of J1 and J2
Comes with 3 DuPont lines.
Support 98/98SE/ME/2000/XP/MAC OS8.6/ Win7-32/64 , Win8-32/64,Win10-3
The RS485 Board (3.3V) is an accessory board used for adding the RS485 transceiver to your application board.The RS485 Board (3.3V) features a SP3485 onboard, integrates pinheaders and connectors to support multiple communication interfaces. It is designed to use 3.3V power supply.
SP3485, control interface, communication interfaces
1, Onboard TLC5615 chip, TLC5615 is DAC with serial interface, Output is voltage, maximum output voltage is twice the value of the reference voltage, with a power-on reset function, The performance is better than the early current output DAC, only need three serial bus-line, can finish 10-data serial input, easy interface with industry standard microprocessor or microcontroller (MCU)
