It supports a versatile power supply range of 3-5.5V and features 15KV ESD protection for enhanced durability. The module comes with six DuPont wires and is marked for easy pin identification, ensuring a user-friendly experience. ## Description Uses： The TTL serial port communicates with the RS232 level device. Serial expansion of the device. RS232 port communication with computer PC. Can be used for GPS, electronic compass, car detection, hard disk maintenance etc .(Need the user staff with a certain degree of professional knowledge and operational capabilities) Description: Supports 3-5.5V power supply. RS232 can choose male or female. The package contains six DuPont wires. Use high-quality chips. In order to facilitate the use of the product, each pin is marked, and a schematic diagram of the product is printed on the back of the product. Instructions for use: (Taking the access MCU as an example, how to connect each row of pins) TTL (UART) side: VCC: DC 3V-5.5V GND: Connect to GND TXD: Connect to MCU.RX (Signal Flow: MCU.RX ← SP3232 ← RS232.TX ) RXD: Connect to MCU.TX (Signal Flow: MCU.TX β†’ SP3232 β†’ RS232.RX) CTS, RTS is not used by default. RS232 side: RXD: Connect RS232.TX (Signal Flow: RS232.TX β†’SP3232 β†’ MCU.RX) TXD: Connect to RS232.RX (Signal Flow: RS232.RX ← SP3232 ← MCU.TX) GND: Connect to RS232.GND CTS, RTS is not used by default. Package Included: 1 pcs TTL to RS232 Module Review: Quality Module - Works with 3.3 VDC - This seems to be a quality TTL to RS232 module. It works well with Raspberry Pi. The 3232 chip appears to be a Sipex SP3232EEN, which based my understanding, is now being produced by MaxLinear. I did not verify functionality for use with hardware flow control, but the CTS and RTS pins are available on the TTL side and every pin on the DB9 connector is soldered to the board. Even the jumpers that came with the module are good quality! Very straightforward to use.

Not a knock off chip. Great for giving a Raspberry Pi, or ESP32 a DB9 serial port. The signal voltage conversion is very reliable. ## Frequently Bought Together - NOYITO TTL to RS232 Module TTL RS232 Male Female Mutual Conversion Module Serial Level Conversion to SP232 TTL Serial Port Communicates with RS232 Level Device 15KV ESD Protect (Female) - EDGELEC 120pcs 10cm Breadboard Jumper Wires Assorted Kit, 15cm 20cm 30cm 40cm 50cm 100cm Optional Dupont Wire 3.9 inch Male to Female Male to Male Female to Female Multicolored Ribbon Cable - HiLetgo 5pcs RS232 to TTL Converter Module COM Serial Port Board MAX3232 MAX232CSE --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/135412332-noyito-ttl-to-rs232-module-male-female-mutual-conversion-module](https://www.desertcart.vn/products/135412332-noyito-ttl-to-rs232-module-male-female-mutual-conversion-module) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-04-26*
