I need to connect my MSP430 microcontroller (3.3V) to interact with a 5V TTL UART camera (http://www.cn-lcf.net/sdp/561974/4/pd-2909996/7575433-2127043/LCF-23M_OV528_Protocol_RS232_Camera_Module.html).
In order to do that I came up with the idea of dropping the camera’s TX port from 5V to 3.3V level by a voltage divider.
The MCU TX to camera RX does not need a voltage divider and since it’s a TTL camera the 3.3V from the MCU shall be enough to drive the camera’s input high (https://dlnmh9ip6v2uc.cloudfront.net/assets/6/d/7/7/4/515385fdce395f0905000000.png).
Will that work?
