Featuring a MAX3232 IC with built-in ESD protection and support for up to 120kbps baud rate, these breakout boards ensure reliable, high-speed data transfer between RS232 and TTL/CMOS logic levels. Each pack includes two mini boards with necessary charge pump capacitors and terminal blocks, making them ideal for microcontroller, modem, and serial printer interfacing in professional and hobbyist electronics projects. ## Description Specification: Dimensions：18.4*27.9mm（0.73*1.1） MAX3232 voltage range: 3V-5V Maximum baud rate: no more than 120kbps Package Includes: 2*mini RS232 to TTL MAX3232 breakout board 2*Terminal bloock Review: good for my 3.3v circuit - These work. They are clearly labeled. The connector is no soldered, which is what I wanted. There are no LEDs on the board, also what I wanted Review: Quality Product and Compact Size - Bought this for a project needing RS232 control with an RPi. The Treedix board is tiny and with soldered-on leads it is small enough to easily tuck inside a regular RPi case, just add a tiny strip of electrical tape to cover the back-end of the leads. I added a 3 pin terminal block to the case for the external plug and ran the RS232 leads to that and mapped the Logic leads to GPIO. Much better than the giant DB9 interface most adapter boards come with. I am buying an extra set just to keep in the project parts drawer. ## Features - This is an RS232 converter IC capaable of operating at 3V and communicating with 5V logic for TTL/CMOS projects. - We use the SOIC package MAX3232 and disconnected all the pins needed to set the RS232 to TTL connection. And it includes the necessary five 0.1uF charge pump capacitors. - Even when operating at a high data rate, MAX3232 can still maintain the minimum transmitter output voltage of ±5.0V required by the RS-232 standard - The chip has ESD protection function, supports flow control, and zero-delay automatic transmission and reception conversion. It worked like a charm and converts the signals to the proper levels. - MAX3232 transceiver breakout board，which can replace MAX232 to complete the matching of 5V system and RS232 high-voltage interface, and also realize the interconnection of 3V low-voltage system and RS232 interface. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09BCKWL8V | | Best Sellers Rank | #389 in Serial Adapters | | Brand | Treedix | | Compatible Devices | Computer, Microcontroller, Modem, Serial Printer | | Connector Type | rs232 | | Customer Reviews | 4.0 out of 5 stars 37 Reviews | | Input Voltage | 5 volts | | Item Package Quantity | 1 | | Manufacturer | Treedix | | Model Number | Treedix-2xMini-RS232-TTL-MAX3232-3V-5V | | Number of Items | 2 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | Electronic | | UPC | 764784797791 741754915270 | | Unit Count | 2 Count | ## Product Details - **Brand:** Treedix - **Compatible Devices:** Computer, Microcontroller, Modem, Serial Printer - **Connector Type:** rs232 - **Number of Ports:** 1 - **Specific Uses For Product:** Electronic ## Images ![Treedix 2pcs Mini RS232 to TTL MAX3232 Convert Adapter Board Transceiver Breakout Board 3v-5v - Image 1](https://m.media-amazon.com/images/I/51XOMsbaZiL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ good for my 3.3v circuit *by B***D on November 21, 2025* These work.
