16X4 CHARACTER LCD 1604 Blue LCD DISPLAY is a dot-matrix liquid crystal display module specially used for displaying letters, numbers, symbols, etc. 16?4 LCD Display can display 4 lines with 16 characters in each line. Divided into 4-bit and 8-bit data transmission methods. 1604 Blue Character LCD provides rich command settings: clear display; cursor return to origin; display on/o; cursor on/o; display character ashes; cursor shift; display shift, etc.
16-channel analog/digital multiplexer/demultiplexer
Routes one signal to/from any of 16 I/O pins
Supports both analog and digital signals (bidirectional)
Operates over a wide voltage range:
HC: 2V to 6V
HCT: 4.5V to 5.5V (TTL compatible)
Low ON-resistance (~60–70Ω depending on voltage)
Fast switching speed (typical ~6ns)
Break-before-make switching to prevent shorting
Minimal leakage current (±0.8 µA typical)
Very low standby power consumption (~8 µA typical)
Built-in Enable pin (active LOW) for full shutdown
Channel selection via 4 digital address pins (S0–S3)
Works reliably in wide temperature range (–55°C to +125°C)
Compatible with microcontrollers like Arduino, ESP32, and Raspberry Pi
Ideal for expanding ADC input, signal routing, or sensor switching in compact circuits
This EasyDriver compatible stepper motor driver module utilizes the Allegro A3967SLB micro-stepping driver to proved a simple and compact means of driving bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors from a microcontroller. By default, the module will accept a 5V TTL step and direction signal from the microcontroller to stop the motor in either full, half, quarter, and eighth-step modes. By shorting jumper SJ2 it can also be configured to be compatible with 3.3V microcontrollers that are not 5V tolerant. An onboard potentiometer allows for setting maximum drive current.
ACS712 Current Sensor 30A current sensor board is based on the Allegro ACS712ELCTR-30A bi-directional hall-effect current sensor chip that detects positive and negative flowing currents in the range of minus 30 Amps to positive 30 Amps. The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current or down -66mV per amp for negative current.
Hall effect sensor is transducing devices used to detect and generate a voltage when in the presence of a magnetic field. They are designed to induce a voltage as an output when a magnetic field is present at its input. The output voltage can be variable depending on the magnitude of the magnetic field. Hall effect sensors, as they name states are effect sensors, which can be used to sense different categories, like speed, position of objects, rotational speed or frequency and be used as a fault detector. They can be used to detect a time-varying current, as time-varying current produce magnetic fields, which can then be sensed by the Hall effect transducer and produce a voltage with some proportion the amount of magnetic field present at the sensor.

he Arduino Leonardo is a microcontroller board based on the ATmega32u4 (datasheet). It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
