Product Introduction of 2/4/8-Channel Level Conversion Module
Some microcontroller development boards and devices operate at 3.3V, while others—including certain microcontroller development boards, devices, and sensors—use a 5.0V power supply. This creates a voltage mismatch when these components need to communicate, causing inconvenience for users. This product is specifically designed to address and solve this issue. It enables compatibility between 3.3V and 5.0V devices, acting as a bridging component for their communication. Additionally, it is available in 2-channel, 4-channel, and 8-channel versions, providing users with multiple options for different complexity requirements.
Except for the difference in the types of bits, the other functions and performance standards of the above-mentioned level converters are identical.

TTL to RS485 Level Conversion Module (Red Version)
It is well known that programming the direction control for 485 signals is quite challenging, especially in scenarios involving unknown communication data protocols. When you don’t know the data volume of each packet, you can’t determine when to switch between transmitting and receiving directions. In such cases, you can choose our store’s 485 automatic direction control module to solve these troubles.
This module comes with protection features that offer exceptional value for money – you can compare it with other 485 control modules.
This TTL to 485 automatic direction control module uses MAXIM’s 485 chips with integrated automatic transceiving functionality. We guarantee that every chip is brand-new and original, making it safer and more reliable than other automatic direction control methods (please refer to the detailed parameters below for specifics, which are absolutely unmatched by other 485 automatic direction control modules).
It is recommended to power the module with 5V (since the 485 signal level range is 2-6V, using 3.3V power supply will reduce reliability for long-distance transmission). However, the module can be controlled by both 3.3V and 5V signals (Note: 5V power supply with 3.3V signal control is fully supported, as we have implemented signal protection measures for your peace of mind).
If you have strict requirements for signals, this module is your ideal choice. It features automatic direction control with a maximum baud rate of 500Kbps, and can automatically recognize baud rates below 500Kbps without manual intervention.
Features of TTL to RS485 Level Conversion Module (Red Version)
1. We guarantee that all chips are brand-new, original imported imported industrial-grade chips, with ultra-long-distance transmission capability of up to thousands of meters.
2. Equipped with ±15KV ESD protection.
3. The chip features a slew rate limited driver, which minimizes EMI and reduces signal reflections caused by improperly terminated cables, enabling error-free signal transmission rates up to 500Kbps.
4. With a receiver input impedance of 1/4 unit load, it supports multi-machine communication and allows connection to a bus with up to 128 devices.
5. The industrial-grade chip can operate within a temperature range of -40°C to +85°C.
6. This module supports hot-swapping without the signal latching issue that occurs with other 485 chips during hot-swapping.
7. The power supply uses chip tantalum electrolytic capacitors, with dual capacitors for high and low frequency power filtering.
8. Utilizes dual transient voltage suppressor diodes for superior overvoltage protection performance.
9. Incorporates a 10Ω current protection resistor, with a chip design that improves 485 signal integrity.
10. Features terminals and welding lead holes for convenient debugging and final version wiring; welded leads can enhance signal reliability.
11. All RS485 and TTL signals are routed on a single layer to ensure signal quality and improve signal integrity.
12. Large-area copper cladding to prevent signal interference.
13. Equipped with 2.54mm pitch perfboard welding holes for easy secondary development.
14. Has the currently commonly used M3 screw holes for convenient and reliable installation.
15. Includes a 120Ω termination resistor; shorting R16 enables the termination resistor.
16. Equipped with power, RXD, and TXD signal indicators for clear visibility of transmission and reception status.
17. Right-angle pins are led out for easy testing.
18. Supports 3.3V and 5V signal control for stronger compatibility.

TXS0108E 8-Bit Bidirectional Voltage Translator
The TXS0108E is an advanced 8-bit bidirectional voltage-level translator designed to solve communication problems between devices operating in different voltage domains. Its core feature is automatic direction sensing; it requires no additional direction control pin, as the data lines can automatically determine and facilitate bidirectional data transmission based on the input signals on either side, greatly simplifying system design. It supports any voltage translation combination from 1.2V to 3.6V (e.g., 1.8V ↔ 3.3V) and features a unique built-in edge accelerator that effectively mitigates signal slowdown (slower rise/fall times) caused by level shifting. This ensures high-speed data transmission in both open-drain and push-pull output modes, making it ideally suited for bidirectional bus applications such as I²C, UART, and SPI.
Main applications:
– Communication compatibility between 5V microcontrollers and 3.3V modules
– Communication compatibility between 3.3V microcontrollers and 5V modules
– Level conversion for communication between microcontrollers and SD cards
– Level conversion for microcontrollers and I2C, SPI, UART devices

Mini MAX3232 RS232 to TTL Level Conversion Board Connection Tutorial
The following is the front access diagram of the module. The power supplies on both sides are connected together, so only one side needs to be connected, and the two independent channels on both sides can be used. The arrows indicate the signal flow direction. Inward indicates input, and outward indicates output. The end close to the RS232 characters is at RS232 level, and the end close to the TTL characters is at TTL level.
