It allows to extract a compatible TTL signal with that coming from a serial COM port.
To communicate with MCU, microcontroller and demoboard, which accept only TTL signals, you need to convert the voltage output from the port using a circuit capable of adapting such signals with logic levels 0 and 5V, while respecting the RS232 communication protocol.
The adapter is fully assembled in its SMD components, including the 9-pin serial connector.
The connector strip with standard pitch 2.54mm and the integrated technology, make this module fully compatible with breadboard, cards for rapid prototyping, breadboard, microcontrollers and demoboard.
Operating voltage: 3 ~ 5.5 V
Connector: DB9 female
Dimensions: 45 x 31 mm
Strip connection: 2.54mm
