2 pieces Mini RS232 TTL UART Modules with MAX3232 interface chip.
Power supply and TTL voltage level 3.3 or 5V.
RS232 voltage level of -5 to -15V and +5 to +15V.
• Operates with 3 to 5.5V supply voltage
• Operates up to 250 kbit/s
• Low supply current: 300 μA Typical
• Accepts 5V logic input with 3.3V supply voltage
• Dimension <16 x <10 mm
The MAX3232 device consists of a pair of line drivers and receivers, and a charge-pump circuit for the RS232 output level. The device meets the requirements of TIA/EIA-232-F and provides the electrical interface between an asynchronous communication controller and the serial-port connector.
