Amp -Access to Serial Port Module Highlights Generic Brand Access to Serial Port Module Description: ADI ADUM3201 magnetic isolation chip, high speed, good waveform, power consumption much lower than photoelectric isolation , large-pitch isolated power supply, no external power supply, just plug in the USB interface. Increase insulation gap, board grooving, better avoid creepage, improve safety performance, integrate protection diodes, improve protection. USB-A male connector, no need to plug the cable, directly plug it into the USB port of the computer to use. The communication level can easily be switched to 5 V or 3.3 V via the jumper cap. VCC output voltage can be 5V/3.3V output. The communication level and the VCC voltage can be the same or different. The TX routes the TX-D independent output (open-drain output) through the reverse diode, which is convenient to connect and burn the STC microcontroller, on-board power supply, transmit and receive three LED indicators. Specification: Material: other Blue Color Size: 54x23x20mm/2.13x0.91x0.79inch Package includes: 1 x FT232 Serial Port Module Note: Color may be slightly different due to the color calibration of each monitor. Please allow slight measurement deviation due to manual measurement.
