diustou SP3232 Isolated RS232 to TTL Converter Module with Metal Enclosure Industrial Serial Port Adapter Board with Electrical Isolation Protection 3.3V/5V DB9 Male

[Chip Program] Adopt industrial-grade chip SP3232 chipset, good compatibility, to meet the TTL 232 interface direct inter-conversion communication, baud
rate support range: 150K bps ^^ [Pin protection] TTL terminal RXD, TXD, RTS, CTS pin with overcurrent protection, RS232 terminal RXD, TXD, RTS, CTS pin with overcurrent protection, electrostatic protection circuit. ^^ [Isolation Circuit] DB9 male interface and 3.5 mm screw type terminal, large package components, more stable and reliable, with independent power isolation and magnetic coupling isolation circuit. ^^ [Signal Compatibility] When using the TTL terminal need to be connected to the 5V power supply, TTL signal terminal output signal level of 5V (the same as the power supply voltage), the input signal level of 5V (compatible with 3.3V signal input) ^^ [Optimized for use] Aluminum alloy case, oxidized and frosted, with positioning holes, and a three-color LED indicator on board, which is used to indicate the power status of the circuit and the sending and receiving status of the signal.
