Yl105 Datasheet — !free!
Because the YL105 is not an official semiconductor part but a module assembled from standard components, no single PDF exists from a major brand like Texas Instruments or STMicroelectronics. However, you can obtain equivalent technical data from:
void setup() pinMode(hallPin, INPUT); pinMode(ledPin, OUTPUT); Serial.begin(9600);
Pass-through logic pin. Governs the primary operational state machines (TX/RX) of the radio module.
For full compliance and detailed physical properties, you can reference the official Alpha Wire Master Catalog or technical data from distributors like DigiKey and Mouser . Alpha Wire F2211IN YL105 - Heat Shrink Tubing - Utmel yl105 datasheet
Based on the yl105 datasheet for the Hall IC, the internal architecture consists of:
If you need help building out a project using this module, please let me know:
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 Because the YL105 is not an official semiconductor
) while establishing clean wireless control links up to several hundred meters away.
The module converts the 2x4 header to a 1x8 header, allowing easy insertion into a breadboard.
: It converts the module's 2x4 (8-pin) header into a breadboard-friendly single-row header with clearly labeled pins. 3. Pinout and Connections For full compliance and detailed physical properties, you
Optional. Can be left disconnected for most basic projects. 2. YL-105 Socket Pinout (For nRF24L01)
Up to 800mA (Sourced via the integrated AMS1117-3.3 LDO)
