Whether you are automating your home, building a robot, or designing a safety cutoff, the YL105 offers a reliable bridge between the fragile world of microcontrollers and the demanding realm of high-power electronics. Always respect the voltage ratings, adhere to proper wiring practices, and consult the SRD-05VDC-SL-C and PC817 datasheets for deeper technical insight.
Rated for operation in industrial temperature ranges. 2. Technical Specifications (Typical Values)
: Optional pin that triggers a low signal on packet delivery or transmission errors. Applications in Wireless Engineering yl105 datasheet
: Connects to the system Ground . A common ground must be shared between the MCU, the adapter, and any external batteries.
The primary purpose of the YL-105 module is to solve the pervasive power supply issues that plague DIY RF networks. While the data pins on an nRF24L01+ transceiver are 5V tolerant, the main power supply line () is strictly limited to 3.3V. Feeding 5V into the transceiver will destroy the IC, while drawing 3.3V directly from an Arduino's onboard regulator frequently causes transmission failures due to insufficient current capacity. The YL-105 eliminates these failure points by regulating a 5V input down to a stable 3.3V rail while filtering out high-frequency noise. Technical Specifications and Absolute Maximum Ratings Whether you are automating your home, building a
Use the YL-105 adapter to safely power the nRF24L01 from 5V. Connecting the 3.3V nRF24L01 chip directly to 5V will likely destroy it.
For applications requiring greater mechanical protection, the FIT®‑300 series offers a semi‑rigid wall and a higher 2.5:1 shrink ratio. A common ground must be shared between the
The YL-105 is a low-cost, low-power wireless transceiver module designed for various short-range wireless applications. It is based on the RF chip by AMICCOM. It operates in the 2.4GHz ISM band (Industrial, Scientific, and Medical frequency band).
