This module can be used for serial port expansion, I2C interface EEPROM and SPI interface FLASH, as well as STC microcontroller programming, program debugging, data acquisition and other aspects. Parameter: Support parallel port: Support USB to printer parallel port and EPP or MEM parallel port. Support serial port: support USB to UART, I2C, SPI interface. Output voltage: The output voltage and level signal can be selected from 3.3V or 5V. On-board UART and SPI / I2C working status indicator. Size: 45x27x10mm (LWH) Pacakge Included: 1pcs NOYITO CH341A USB Serial Port Parallel Port Converter Module Review: Working as expected - Bought 4, got them working quickly just googling drivers, had to use a meter to confirm a few pin assignments but everything works as expected. Have read i2C sensors and drawn on SPI displays with no problems! Review: Works (but not ideal) for GPD Win 4 display fix - I was using this to flash firmware onto a GPD Win 4’s I2C chip. While this ultimately worked fine, there was no wiring diagram available. I had to do some internet sleuthing to figure out where to plug in my cables. Using a “black” CH341A chip, which is what the guide used in the first place, is probably a better bet to get things working correctly. ## Features - The NOYITO CH341A conversion module is equipped with a CH341A chip, which is a USB bus transfer chip that provides asynchronous serial ports, print ports, parallel ports, and commonly used 2-wire and 4-wire synchronous serial interfaces through the USB bus. - This module can be used for serial port expansion, I2C interface EEPROM and SPI interface FLASH, as well as STC microcontroller programming, program debugging, data acquisition and other aspects. - Support parallel port: Support USB to printer parallel port and EPP or MEM parallel port. - Support serial port: support USB to UART, I2C, SPI interface.（The second picture on the left is the setting operation diagram） ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B082KQ75QM | | Best Sellers Rank | #219 in Serial Adapters | | Brand | NOYITO | | Compatible Devices | USB to UART IIC SPI TTL ISP EPP MEM Parallel Port | | Customer Reviews | 3.5 out of 5 stars 23 Reviews | | Hardware Interface | Internal Solutions Port, USB | | Item Type Name | USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter | | Item Weight | 0.01 Kilograms | | Manufacturer | NOYITO | | Model Number | CH341A | | Operating System | Windows 10 | | Style | USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter | | Style Name | USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter | | UPC | 680613663818 | | Unit Count | 1 Count | | Warranty Description | Manufacturer's One-year After-sale Warranty | ## Product Details - **Brand:** NOYITO - **Hardware Interface:** Internal Solutions Port, USB - **Style:** USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter - **Item Weight:** 0.01 Kilograms - **Compatible Devices:** USB to UART IIC SPI TTL ISP EPP MEM Parallel Port ## Images ![NOYITO CH341A USB Serial Port Parallel Port Converter Module USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter Module - Image 1](https://m.media-amazon.com/images/I/81BnU8viO2L.jpg) ## Questions & Answers **Q: Where is the data sheet? does this look like a serial port on a pc? what is the data rate? 2m??? 2mbit or 2mbyte?** A: It is a USB bus transfer chip that provides asynchronous serial ports, print ports, parallel ports, and commonly used 2-wire and 4-wire synchronous serial interfaces through the USB bus.

Have read i2C sensors and drawn on SPI displays with no problems! ### ⭐⭐⭐⭐ Works (but not ideal) for GPD Win 4 display fix *by K***N on October 28, 2025* I was using this to flash firmware onto a GPD Win 4’s I2C chip. While this ultimately worked fine, there was no wiring diagram available. I had to do some internet sleuthing to figure out where to plug in my cables. Using a “black” CH341A chip, which is what the guide used in the first place, is probably a better bet to get things working correctly. ### ⭐ Driver Installation Does Not Work *by C***N on April 8, 2023* Documentation is sparse, and it does not include the driver installation. I downloaded everything but the documentation does not offer anything new that is already on the web page. After driver installation, Windows 11 still shows "Unknown Device" in the device manager. ## Frequently Bought Together - NOYITO CH341A USB Serial Port Parallel Port Converter Module USB to UART IIC SPI TTL ISP EPP MEM Parallel Converter Module - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - MCIGICM 10pcs Male Header Pin, 40 Pin Header Strip (2.54 mm) for Arduino Connector --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pe/products/178782027-noyito-ch341a-usb-serial-port-parallel-port-converter-module-usb](https://www.desertcart.pe/products/178782027-noyito-ch341a-usb-serial-port-parallel-port-converter-module-usb) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-07-05*
