Frequently asked about this product
How does the I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) link to my microcontroller?
The I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) links over a UART serial connection (TX/RX at 3.3 V TTL, XH2.54 or header pins). Connect it to any Arduino, ESP32 or micro:bit (via adapter) serial port, set the baud rate, and exchange data with simple serial commands — no special driver needed.
What voltage does the I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) run on?
The I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) runs from a standard 3.3-5 V DC supply (USB or the controller’s 5 V rail). It draws only a few milliamps in normal operation, so it is safe to power from the controller board itself for classroom builds.
What projects is the I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) good for?
The I2C 2.4 G Wireless Remote Receiver (PCF8574, 8 CH) is built for STEM and robotics education: classroom demonstrations, science-fair projects, robotics club builds and competition robots. It pairs with the rest of our module range — same connectors, same voltage, same toolchain — so students move from first circuit to competition robot without changing platforms.
What certification do the robotics and electronics products carry?
Controller boards, sensors and modules ship with CE marking and RoHS-compliant components, and the range is designed for classroom use under teacher supervision. Product-specific test reports and declarations of conformity are available for distributors on request.
What is the minimum order quantity, and can I get a sample first?
These are standard catalogue lines with stable production, so minimums are low and lead times are short. Samples ship within about a week and are normally credited against a first order. Mixed-SKU cartons are accepted for evaluation orders.
