Mini RS232 to TTL Level Converter Board
The MAX3232 module is an RS-232 Transceivers Module with DB9 Female Connector, compliant with TIA/EIA-232-F standards and gives the designers an electrical interface between an asynchronous communication controller and the serial-port connector. It can work up to 250 signal rates with a maximum of 30-V/μs driver output slew rate.

The Mini RS232 MAX3232 Level Turn to TTL Level Converter Board / Serial Port Converter Board has one purpose in daily life – to convert RS232 to TTL and vice versa (TX RX RTS and CTS). It will allow a microcontroller to communicate with a computer. This board is powered by the target application and can run from 3V to 5V! That s right – power the board at 5V, and the unit will convert RS232 to 5V TTL. Power the board at 3V, which will convert RS232 to 3V CMOS TTL. It includes two indicator LEDs for TX and RX. Moreover, it runs from 300bps up to 120Kbps.
Features:
- High speed, replaceable MAX232 based. The device fitted supports up to 120kbps.
- Works with PCs or Laptops
- Supports microcontroller UARTs 5V TTL signal levels.
- Single DC supply: wide input range for 4201 or 5V for 4202 and 4203
- Small PCB footprint of 5040mm
- Low current status LED(s)
- Very low power consumption
- Optional onboard PSU for internal/external use for a quick start out of the box.
- Power can be routed to pin 9 (if required) on the RS232 connector useful for specific applications.
