About this product
An I2C multiplexer board built around the TCA9548A (or PCA9548A) chip, which splits one I2C bus into eight switchable channels. It lets you connect several I2C devices that share the same address, such as multiple OLED displays or sensors, by selecting one channel at a time. Useful for Arduino and ESP32 projects.

Frequently asked questions
What is the price of TCA9548A PCA9548A I2C 8-Channel Multiplexer Expansion Module in Egypt?
TCA9548A PCA9548A I2C 8-Channel Multiplexer Expansion Module currently costs 155 EGP in Egypt.
Where can I buy TCA9548A PCA9548A I2C 8-Channel Multiplexer Expansion Module in Egypt?
TCA9548A PCA9548A I2C 8-Channel Multiplexer Expansion Module is available from UGE. Compare the offers above to find the best price.
How do I select a channel?
Write a byte to the chip's control register over I2C, where each bit enables one channel. The datasheet describes the control register and the bit mapping in detail.
How do I change the multiplexer's address?
The address is set by the A0, A1 and A2 pins, giving a range of 0x70 to 0x77. Use different address settings when two multiplexers share the same I2C bus.
