Jdy-40: Arduino Example ((new))

The JDY-40 is a 2.4GHz wireless serial module suitable for low-power, short-distance (120m) data transmission using a UART interface. Operating at 3.3V, it requires proper pin configuration (SET, CS) and AT commands to establish transparent transmission, often interfaced with Arduino via SoftwareSerial .

The JDY-40 is a . While its RX/TX pins are often 5V tolerant, it’s best practice to use a voltage divider or level shifter when connecting to a 5V Arduino Uno. The JDY-40 is a 2
