FT232RL USB To Serial Port USB To TTL 1.8V 3.3V Arduino Android

Title： FT232RL USB to Serial Port USB to TTL 1.8V 3.3V Arduino Android Specification: The new batch of the 2021 version of the converter has been launched. The 2021 batch of imported chips is used, the IO protection circuit is strengthened, and the 5V, 3.3V, 1.8V level jumper selection is supported.The current delivery is the latest version!YS232RL-USB to serial adapter USB to UART USB to TTL FT232RL industrial-grade chip, imported from the UK. This converter is TTL level: no need to provide external voltage, directly support 3.3V, 1.8V and 5V (other desired level voltages can also be input externally, such as 2.5V 2.8V 3.0V, etc.) The 6-pin interface signal of the converter is defined as the commonly used CTS RTS RXD TXD GND VCCAll signal levels of the 6-pin interface are 3.3V, 1.8V and 5V, jumper caps are availableNote: Friends who need to support Arduino download can open the shell and configure it according to the mark (requires desoldering resistance)! ! The converter can be configured by adjusting the 0R resistance inside the converter as:1. Output DTR signal and share pin with CTS signal. At this time, CTS pin signal is DTR (mainly downloaded for Arduino).2. It can be directly connected to other types of voltage, such as 2.8V, and the output TTL level is 2.8V (need to remove the level selection jumper cap).In general, only three wires of RXD TXD GND are sufficient when used. VCC is not connected when the target board does not need converter power supply. Self-test method: first short-circuit RXD TXD, and then send data to the port through the serial port assistant, RXD will receive the data sent by TXD and display it in the data receiving area of ​​the serial port assistant. This process is usually called a loopback test, or spontaneous transmission and reception of a serial line. Package: 1*converter module
