Mini RS232 to TTL level converter

This module is suitable for projects requiring a RS232 to TTL logic interface. It’s bi-directional and ideal for use in pc interfacing, microcontroller based projects or for experimental and educational purposes.Because the design of this board is based on the MAX3232, it operates at a broader voltage range than the MAX232 (3 – 5.5V), which means you can use this on both your 3.3 and 5V projects!SpecificationsVoltage range: 3-5 VSize: 9.5*16 mm (VERY SMALL!)Baud rate: up to 120 kbpsVery low power consumptionSupports any micro-controller with UART communicationConnections:You can also use the SoftwareSerial library and set different pins instead of the digital pins 0 and 1 (TX/RX)in order to avoid troubles with the microcontroller serial communication.DocumentsDatasheet
