USB to TTL Serial Modules Multi Level Serial Converter Supports 5V/3.3V/2.5V/1.8V Quad Level Switching Optional Serial Master Chip FT232 CH340 CP2102 High Speed Stable USB to uart Module (TA,FT232RL)
USB TO TTL, support 5V/3.3V/2.5V/1.8V four level switching, adapting to different voltage system, using a dip switch to select the voltage, without power failure operation.
USB port with electrostatic protection and current protection. Signal interface RX, TX, CTS, RTS port with current protection and ESD protection.
Pin out CTS, RTS signal pins, FT232, CP2102 version additional pin out DTR, DSR, DCT pins, can be convenient for hardware flow control.
Adopt chip conversion program, non-transistor program, the low level is 0V (transistor program due to the conduction voltage drop, the low level can not reach 0V)
