Digital 38KHz Infrared Receiver module
KSh 150.00
DESCRIPTION
The 38KHz IR Digital Receiver Module is surprisingly complex for its size, with 38KHz modulation, advanced filtering and versatile binary output signals.
APPLICATION
- DIY Microcontroller Projects: Widely used with platforms like Arduino and Raspberry Pi to build wireless control projects.
- Universal Remotes & AV Systems: Used to build smart home hubs or replace receivers in set-top boxes, stereos, and TV control systems.
- Robotics & Toys: Enables remote-controlled movement, turning motors on/off, and activating servo actions from a distance.
- Object & Obstacle Detection: When paired with a 38KHz IR transmitter, it acts as a proximity sensor for robot navigation.
- Home Automation: Used for custom wireless light switches, fan control, and garage door triggers.
2 Channel Logic Level Converter 3.3V-5V UART IIC SPI
KSh 200.00
DESCRIPTION
The 2 Channel Logic Level Converter is a small device that safely steps down 5V signals to 3.3V and steps up 3.3V to 5V.
FEATURES
Bi-Directional Translation: Translates signals both ways (up and down) without requiring direction-control pins.
Voltage Compatibility: Steps down 5V signals to 3.3V and steps up 3.3V to 5V. It is also widely compatible with 1.8V and 2.8V devices.
Channel Capacity: Features two independent, high-speed channels suitable for protocols like I2C (SDA/SCL) and UART (TX/RX).
Breadboard-Friendly: Compact in size and designed with standard pin spacing for direct mounting onto a breadboard.Simple Wiring: Requires both the high-voltage 5V and low-voltage 3.3V sources to be connected to the board, alongside a common ground.
Dimensions 15 x 15 x 2mm
Weight 2g
APPLICATION
TTL Logic Level Converter
Bidirectional Logic Level Conversion
I2C Sensor Integration: Level shifts the Serial Data (SDA) and Serial Clock (SCL) lines. This allows you to connect 5V systems (like a classic Arduino Uno) to low-voltage sensors (like modern temperature or IMU chips).
UART Serial Communication: Converts Transmit (TX) and Receive (RX) lines so a 3.3V device (e.g., a Raspberry Pi) or wireless module (e.g., ESP8266/ESP32) can communicate with a 5V MCU without frying its pins.
Legacy Component Upgrades: Lets you integrate new 3.3V shields and expansion boards into older 5V mainboards, or vice versa, over standard two-wire digital buses.
General Purpose 2-Wire Digital Bus: Handles various 2-wire bidirectional communication buses like 1-Wire, ensuring voltage domains remain isolated.
Infrared Transmitter Module KY-005
KSh 150.00
DESCRIPTION
The IR Emitter Module emits infrared (IR) as is commonly used for creating an IR remote control or IR intrusion sensor.
APPLICATION
- Smart Home Automation: Emulates standard appliance remotes to control TVs, stereos, and air conditioners.
- Wi-Fi-to-IR Bridges: Acts as a universal remote when connected to an ESP8266 or ESP32, allowing you to control IR-reliant devices via voice assistants or smartphones.
- Wireless Data Communication: Transmits short-range, line-of-sight data (such as sensor readings or basic commands) between microcontrollers or simple robots.
- Proximity & Obstacle Detection: Functions as a short-range sensor when paired with an IR receiver module (like the KY-022 IR Receiver); the receiver detects the reflected IR light emitted by the KY-005 to gauge distances or avoid obstacles
