RS232 Module 13.2 with DB9 Female Connector Brand_Troika There is only one I2C

There is only one I2C address so it's not a good option when you need multiple humidity sensors

096 volt precision voltage reference

which provides UWB communication capabilities

3V-6V but the luminance will be different

Supports network protocols such as TCP/IP/IPV4/IPV6/Multi-PDP/FTP/FTPS/HTTP/HTTPS/DNS

RS232 Module 13.2 with DB9 Female Connector Brand_Troika There is only one I2CThe RS232F Module 13. 2 is an expansion module of the RS232 serial communication with isolation, using the scheme of the TD301D232H serial port conversion chip and the female DB9 interface to give the interface conversion between RS232 and TTL CMOS logic level signals, and uses the F0505S 2WR3 DC DC power module to enable electrical and noise isolation function. With a toggle and coding switch, it can enable the pass through or cross switching of DB9
