Description

The device RS-232 Transceiver breakout by Soldered uses the MAX232E IC for bidirectional conversion between TTL/CMOS logic levels and RS-232 voltage levels. It allows a microcontroller to communicate with devices using RS-232, including industrial equipment, modems, barcode scanners, and legacy communication devices.

The MAX232E provides two transmit channels and two receive channels, allowing simultaneous data transmission and reception in full-duplex mode. The DIN1 and DIN2 lines accept logic-level signals for transmission, while DOUT1 and DOUT2 provide the corresponding RS-232 signals. In the receive direction, RIN1 and RIN2 accept RS-232 signals, while ROUT1 and ROUT2 provide the converted logic-level signals.

RS-232 uses bipolar voltage levels, with the manufacturer documentation specifying a range of ±3V to ±15V for the RS-232 side. The charge pump integrated into the MAX232E generates the voltages required for RS-232 communication from a single supply. The IC also incorporates ESD protection to increase resistance to electrostatic discharge.

The manufacturer documentation specifies a board supply voltage range of 3,3–5.5V, with a nominal supply of 5V. A basic microcontroller connection can use one channel, with TX connected to DIN1 and RX connected to ROUT1. The second channel provides an additional independent communication path.
