Used for wire harness bundling, strain relief, and electrical insulation on circuit boards. Its flame‑retardant properties help prevent short circuits and protect against environmental moisture.
: The nRF24L01 module requires a strict 1.9V to 3.6V supply. Standard Arduino 3.3V pins often lack sufficient current stability, leading to "brownouts" and dropped connections. The YL-105 allows you to use the more robust 5V rail.
Designed to handle momentary spikes without thermal runaway. yl105 datasheet
2.4GHz wireless transceiver module. Its primary purpose is to simplify the power requirements of the radio module, which is sensitive to voltage fluctuations. Instructables Key Technical Specifications
The polyolefin formulation resists many common industrial chemicals, oils, and solvents. The FIT‑300 series is also highly resistant to abrasion and moisture, making it suitable for harsh environments. Used for wire harness bundling, strain relief, and
