  • 【TCA9548】TCA9548A 8 Channel I2C IIC Multi-channel Expansion Board 1-to-8 TCA9548 8-Way
  • 【Compatible】The adapter is connected to an I2C device with multiple identical addresses on the same I2C port on the main control board for normal communication and use. Compatible with IIC bus and system management bus (SMBus), active low reset input, support for hot insertion, low standby current, no glitch during power-up, support for voltages between 1.8V, 2.5V, 3.3V and 5V buses Level shifting.
  • 【Design compact】There are 8 I2C interfaces on one expander, and there are eight bidirectional transfer switches that can be controlled by I2C bus. This means that after 1 expander is transferred, 8 identical addresses can be connected to the same I2C port. The device is also in normal use. The default address of this expander is 0x70, the address can be changed, and can be set within 0x70~0x77 according to your needs.
  • 【Description】The switch has a turn-on gate so that the VCC pin can be used to limit the maximum high voltage through the TCA9548A. Limiting the maximum high voltage allows different bus voltages to be used on each channel pair so that 1.8V, 2.5V or 3.3V components can communicate with 5V components without any additional protection, for each channel, external pull-up resistors The device pulls up the bus voltage to the desired voltage level. All I/O pins are 5V withstand voltage.
  • 【High performance】In theory, 8 expanders can be cascaded in the address of 0x70~0x77, and each expander can connect 8 devices with the same address. This realizes the same I2C port and connects 64 devices with the same address and uses them normally. Very powerful!

  • Raspberry Pi is a common main control board with powerful functions. However, the pins of the Raspberry Pi main control board can only read digital signals. If you need to read the signals of analog sensors or devices, you can only connect an analog-to-digital conversion (ADC) module, which is not convenient to use.
  • The ADS1115 16-bit AD conversion module can accurately collect and convert analog signals. Through this AD module, the Raspberry Pi main control board can be very conveniently compatible with the Arduino series of analog sensors, measure various signals, and perceive this world.
  • ADS1115 16-bit AD conversion module is specially designed for Raspberry Pi compatible with Arduino series analog sensors, which greatly reduces the difficulty of Raspberry Pi main control board compatible with Arduino series analog sensors, plug and play, no soldering, very convenient.
  • This module uses the 16-bit ADC chip ADS1115, which supports a wide voltage supply from 3.3V to 5V. The chip has a precision reference voltage and programmable gain adjustment (PGA), so it can be used for weak signals or signals with large changes. Accurate acquisition and conversion, so this module is also suitable for all kinds of occasions where the main control board needs to accurately collect analog signals.
  • One AD module can read 4 channels of analog signals. Due to the onboard I2C address selection switch, it supports the cascade of 2 AD modules and reads 8 channels of analog signals, which is sufficient to meet the needs of various scenarios.
