Schnittstellenmodule
Schnittstellenmodule verbinden, was nicht zueinander passt: einen Mikrocontroller mit einem USB-Anschluss, eine RS-232-Leitung mit einer UART, einen PC mit einem RS-485-Bus. Es sind fertig aufgebaute Baugruppen; auf der USB-Seite wird der Treiber des jeweiligen Wandlerbausteins benötigt.

Welches Modul?
| Modul | Verbindet | Besonderheit | Artikelnummer |
|---|---|---|---|
 USB-A UART Bridge CP2104 | USB-A ↔ UART | Versorgt den Mikrocontroller mit bis zu 100 mA aus dem USB, GPIOs 0–3 nutzbar | 901.077 |
 USB-A UART Bridge CP2102 | USB-A ↔ UART | Der schlanke Klassiker, steckt unmittelbar in der Buchse | 901.023 |
 USB-B UART Bridge CP2102 | USB-B ↔ UART | Feste Buchse statt Stecker — für den Einbau ins Gerät | 901.190 |
 USB UART Bridge ISO | USB-B ↔ UART | Galvanisch getrennt — wenn Masseschleifen oder Potentialunterschiede drohen | |
 USB-RS485-Bridge | USB ↔ RS-485 | Für den Feldbus; auch im Gehäuse lieferbar | 901.274 |
 USB-B-RS232 Bridge | USB-B ↔ RS-232 | Ersetzt die fehlende serielle Schnittstelle am Rechner | |
 RS232(DTE)-UART-Bridge | RS-232 ↔ UART | Pegelwandler, Bauart DTE — das Gerät gibt sich als Endgerät | 901.191 |
 RS232(DCE)-UART-Bridge | RS-232 ↔ UART | Pegelwandler, Bauart DCE — das Gegenstück dazu | 901.193 |
DTE oder DCE? Die beiden RS-232-Brücken unterscheiden sich in der Belegung von Sende- und Empfangsleitung. Ein Nullmodemkabel vertauscht diese Leitungen und macht die eine Variante an der Stelle der anderen verwendbar.
Funkstrecke statt Leitung: Die ICT RS485-Funkbridge überträgt dieselben seriellen Daten über 868 MHz und ersetzt damit die Leitung zwischen zwei Teilnehmern.
Die Module im Einzelnen
USB-A UART Bridge CP2104
USB-A UART Bridge CP2104
The USB-UART-Bridge connects UART components with a USB-Host. The Bridge generates a 3.45V Voltage from USB. This can be used to supply the microcontroller over a jumper (maximum 100mA@3.45V).
Features:
- Baud rate: 300Bit/sec up to 2MBit/sec
- GPIOs 0-3 are set to push/pull at delivery state! (so LEDs, TxEN and GPIO are working)
- Voltage-regulator: up to 100mA@3.45V
- LEDs: Power, RX and TX
- IO: RX ( to connect with RX on the µC),TX (to connect with TX on the µC), GND, VCC
- Size: (LxWxH)(mm): 52.0 x 17.0 x 5.2
