  • This expansion board adds two RS485 ports and two RS232 ports for Raspberry Pi 5, which can meet your various needs to use Raspberry Pi 5, such as using the Raspberry Pi 5 to make robot to control robotic arm, industrial automation control system, data acquisition and monitoring systems, automotive electronics, etc.
  • PCIE to 4-way USB2.0 design, one USB2.0 for 4-way RS485 RS232 serial port expansion, the other three USB2.0 leads out through 1.25mm 4Pin connector, which can extend the CM4 4G Mini module.
  • Through the USB2.0 high-speed interface to transfer out four serial ports, adopt the design of two RS232 and two RS485 (with power isolation). The two RS232 can be converted to TTL/CMOS level UART and lead out via 2.54mm 3Pin pins. The 3Pin pins need to be soldered by yourself.
  • The baud rate of RS232 can be more than 230Kbps (U0 and U3 can be up to 1.2Mbps if carrying out actual measurement); The baud rate of RS485 can be up to 500Kbps (U1 and U2 can be up to 1.5Mbps if carrying out actual measurement).
  • RS232 is suitable for short-distance communication; while RS485 is suitable for long-distance, multi-point communication, supporting multiple devices to communicate over the network. RS485 is a wired transmission protocol, which is widely used in various communication systems due to its feature of long-distance, high-speed and multi-branch structure.

  • Hauptchip: MAX3232; Betriebsspannung: 3,3V-5V; Schnittstelle: TX, RX, GND, VCC; Bauds: 300 bis 115200.Unterstützt 3V bis 5,5V Spannungsversorgung und bietet bidirektionale Datenkommunikation mit Baudraten bis zu 115,2 Kbps.
  • Hinweis: Wenn die kleine Platine in Betrieb ist und VCC mit einer externen 3,3-V-Stromversorgung verbunden ist, leuchtet die Power-LED und das Modul funktioniert. Wenn die Stromversorgung nicht angeschlossen ist und die LED-Leuchte aus ist, funktioniert das Modul nicht.
  • Dieser Konverter kann an einen Arduino Serial Pin (0,1) angeschlossen werden, um Standard Arduino TTL in RS232 zu konvertieren. Damit kann Arduino mit Hunderten von RS232-Geräten kommunizieren.
  • Dieser Konverter verwendet einen MAX3232-basierten Pegelwandler für die Umwandlung von TTL (Transistor-Transistor-Logik) -Level seriell in Standard RS232 seriell.
  • Anwendung: RS232 ist weit verbreitet in Radio-Modifikationen, Telefon-Flash, XBOX360-Flash, GPS, Fahrzeug-Erkennung, DVD-Flash, Festplatten-Reparatur-Set-Top-Box-Upgrade verwendet. Es kann verwendet werden, um STC MCU, NXP MCU, Renesas MCU, STM32 MCU, N+-2EC MCU zu programmieren.
