232 to 485 - 보드상의 DIP 스위치를 이용하여 원하는 변환 모드의 설정이 가능합니다.
특징
- 3.3V and 5 V Compatibility
- Power Output: 5V-500mA or 3.3V-100mA.
- Overcurrent protection : Onboard resettable fuse , even if the positive and negative short-circuit will not damage the circuit board or computer. If there is a short circuit or current exceeds 500mA , the fuse will automatically disconnect , to be short-circuited fuse circuit to restore non- normal .
- Transceiver indicator
- TTL level interface : can be directly connected microcontroller or other embedded devices, such as 51, STC, AVR, ARM, FPGA , etc., without conversion.
RS232 level interface : connect a computer or Rs232 level serial devices.
RS485 level interface : automatic send and receive control without transceiver control line , the default receiving state , to send status line when sending data .
Freedom Huzhuan four levels : a unique circuit design , USB, TTL, RS232, RS485 freedom of conversion, switched by the switch to achieve physical , convenient and reliable , without interference.
High-speed communications : baud rate up to 2Mbps.
DTR, RTS signals: serial module leads the DTR, RTS signal is versatile, supporting MSP430 microcontroller BSL downloads.
