About this product
The MAX232CPE is a +5 V powered RS-232 transceiver with two drivers and two receivers. It converts the 0 to 5 V serial logic levels of a microcontroller into the RS-232 voltage levels used by legacy serial ports, modems and PC COM ports. It generates the required voltages internally from a single 5 V supply using charge pumps.

Why does MAX232 need external capacitors?
Its internal charge pump uses external capacitors to generate the positive and negative voltages needed for RS-232 levels from the 5 V supply. Connect them to the C1+, C1-, C2+, C2-, V+ and V- pins as shown in the datasheet; typical values are 1 µF.
Can MAX232 connect directly to an ESP32 or Arduino?
The RS-232 side connects to a DB9 port or a PC, but the TTL side connects to the microcontroller. Its TTL outputs swing to about 5 V, so use a level shifter or voltage divider before a 3.3 V board such as ESP32.
