Key features
- MCU-based 2.4 G transceiver: one-to-one pairing, interference-free, 8 trigger channels by default.
- Transmitter: 4 buttons plus a four-direction joystick; receiver outputs A-H with LED status (IO version outputs high on trigger, low otherwise; I2C version outputs via PCF8574 in a smaller package).
- Pairing: power the receiver off, install transmitter batteries, hold A and C while switching on until the blue LED blinks, then power the receiver — red LED steady means success; pairing is remembered after power loss.
- Transmitter enters low-power standby when idle (blue LED off).
Frequently asked about this product
How does the 2.4 G Wireless Remote Transmitter link to my microcontroller?
The 2.4 G Wireless Remote Transmitter 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 2.4 G Wireless Remote Transmitter run on?
The 2.4 G Wireless Remote Transmitter 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 2.4 G Wireless Remote Transmitter good for?
The 2.4 G Wireless Remote Transmitter 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.
