I used 3.3V to power the board. George did a good job in the photo section above and it is spot on. My use case was a little different as what I needed was to tap into a RS232 working line and probe it with a logic analyzer. So, it was two RS232 > TTL lines; one on each side of the board. This let me probe both the TX and RX at the same time. I used AI to help me write a program to read the MODBUS output of a MPPT controller. This little board worked great and I learned a lot. Worth the $. Review: works as discribed. - a little fiderly to conect up, work well have used several. ## Features - HiLetgo Level Converter Board Mini TTL Rs232 - Voltage Range: 3V ~ 5V - Chip: MAX3232CSE ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00LUDCAXQ | | Best Sellers Rank | #46,399 in Computers ( See Top 100 in Computers ) #114 in Serial Adapters | | Brand | HiLetgo | | Color | blue | | Colour | blue | | Compatible Devices | Microcontroller, Single-Board Computer, Electronic Circuit | | Compatible devices | Microcontroller, Single-Board Computer, Electronic Circuit | | Connector Type | Serial Adapter | | Connector type | Serial Adapter | | Customer Reviews | 3.6 out of 5 stars 107 Reviews | | Input Voltage | 5 Volts | | Item Weight | 0.02 Kilograms | | Item weight | 0.02 Kilograms | | Manufacturer | HiLetgo | | Mfr Part Number | 3-01-0290 | | Model Number | 3-01-0290 | | Nominal Power | 0.5 Watts | | Number of Items | 10 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | personal | | Specific uses for product | personal | | UPC | 702082655627 | | Unit Count | 10.0 Count | ## Product Details - **Brand:** HiLetgo - **Color:** blue - **Compatible Devices:** Computer, Microcontroller, Devices with Serial Communication or TTL Signals - **Connector Type:** Serial Adapter - **Specific Uses For Product:** personal ## Images ![HiLetgo 10pcs Mini RS232 to TTL MAX3232 to TTL Level Converter Board Serial Converter Board RS232 to TTL Serial - Image 1](https://m.media-amazon.com/images/I/61s-Lgo0BKL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great for my application. *by K***R on 2 January 2026* No issues with heat.

Even the bare minimum solder temperature causes failure.
