TCA9548A I2C 1-to-8 Channel Multiplexer Module
Original price was: 120.00 EGP.99.00 EGPCurrent price is: 99.00 EGP.
TCA9548A I2C multiplexer that splits one I2C bus into 8 separate channels, so you can connect several sensors or displays that share the same address to a single Arduino, ESP32 or Raspberry Pi.
The TCA9548A I2C Multiplexer Module solves the common problem of I2C address conflicts. It sits between your microcontroller and up to eight downstream I2C buses, letting you switch to any channel by writing one byte. This way you can run, for example, eight identical OLED displays or BME280 sensors from one pair of SDA/SCL pins.
TCA9548A I2C Multiplexer Module – Key Features
- Chip: TCA9548A / PCA9548A
- 1 upstream I2C bus to 8 downstream channels (SD0–SD7 / SC0–SC7)
- Address selectable 0x70–0x77 with A0–A2
- Supply voltage: 1.65V–5.5V
- Supports voltage translation between channels
- RESET pin for bus recovery
- Up to 400kHz Fast-mode I2C
Applications
Makers, students and engineers use it in projects such as:
- Multiple identical OLED displays
- Several sensors with fixed I2C addresses
- Mixing 3.3V and 5V I2C devices
- Robotics and data logging projects
Usage Tips
Select a channel by writing 1 << n to the multiplexer address before talking to the device on that channel. Add pull-up resistors on each downstream channel if your modules do not include them.
