Wireless data transmission is fundamental in IoT and embedded systems. While modules like HC-12 (433 MHz) and nRF24L01 (2.4 GHz) are popular, they require significant configuration. The JDY-40 offers a simpler alternative: it appears as a wireless serial cable. Any data sent to its TX/RX pins is transmitted to a paired receiver. This paper documents the minimum working example and characterizes its performance. The JDY-40 is a low-power, 2
