  1. TTL UART to RS485 Converter Module 018-MAX485

    TTL UART to RS485 Converter Module

    SKU: 018-MAX485
    Going from TTL to RS485 is made simple by this prototyping friendly module. On one side of the board are the TTL IOs, and on the other are the RS485. At the core is a MAX485 which is powered by 5V. Learn More

  2. 4-channel I2C-safe Bi-directional Logic Level Converter - BSS138 (ADA757) Image 1 ADA757 Adafruit Australia

    4-channel I2C-safe Bi-directional Logic Level Converter - BSS138

    SKU: ADA757
    Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V. Learn More

  3. DB9 Female Breakout Board 018-DB9F-BREAKOUT-RA

    DB9 Female Breakout Board

    SKU: 018-DB9F-BREAKOUT-RA
    This handy breakout board provides 9 screw-down terminal block connectors for the whole DB9 connector pinout. Every terminal is clearly marked, and we've gone the extra mile by ensuring tall terminal boards are used on the rear set - this allows all your wire connections to flow from one side. Learn More

  4. Logic Level Shifter, 4-Channel, Bidirectional POLOLU-2595 Pololu Australia

    Logic Level Shifter, 4-Channel, Bidirectional

    SKU: POLOLU-2595
    This tiny logic level shifter features four bi-directional channels, allowing for safe and easy communication between devices operating at different logic levels. It can convert signals as low as 1.5 V to as high as 18 V and vice versa, and its four channels are enough to support most common bidirectional and unidirectional digital interfaces, including I²C, SPI, and asynchronous TTL serial.

  5. 8-channel Bi-directional Logic Level Converter - TXB0108 (ADA395) Image 1 ADA395 Adafruit Australia

    8-channel Bi-directional Logic Level Converter - TXB0108

    SKU: ADA395

    The TXB0108 bi-directional level converter performs bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction. Only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse auto-direction sensor). If you need to use pullups, you can but they should be at least 50K ohm - the ones internal to AVRs/Arduino are about 100K ohm so those are OK! Its a little more luxurious than a 74LVX245 but if you just don't want to worry about directional pins this is a life saver!
