4-Channel Level Converter (12V to 3.3V)
This DFRobot 4-channel optocoupler-isolated level converter translates 12V signals down to 3.3V, making it easy to interface industrial sensors and PLC outputs with Arduino, Raspberry Pi, and other 3.3V microcontrollers. Each channel features photoelectric isolation for reliable signal separation...
Adafruit Right Angle VEML7700 Lux Sensor - I2C Light Sensor
·
The Adafruit Right Angle VEML7700 Lux Sensor is an I2C ambient light sensor that measures calibrated lux values rather than arbitrary brightness numbers. Its unique right-angle orientation senses light coming parallel to the PCB surface rather than perpendicular — ideal for edge-lit enclosures an...
Adafruit A4988 Stepper Motor Driver Breakout Board
·
The Adafruit A4988 Stepper Motor Driver Breakout simplifies stepper motor control down to just two pins — a direction pin and a step pin. Each pulse on the step pin advances the motor by one step or microstep, making it straightforward to achieve precise, controlled motion without complex timer o...

Power Bank KeepAlive (USB-C)
·
The Power Bank KeepAlive (USB-C) prevents power banks from automatically shutting off when connected to low-power devices. It uses a 555 timer circuit to pulse a small amount of current through the USB-C port, keeping the power bank active even when drawing minimal power. This assembled SMD vers...
STCC4 + SHT41 CO2, Temperature & Humidity Sensor
·
This compact breakout combines the STCC4 CO2 sensor with a Sensirion SHT41 temperature and humidity sensor for convenient indoor air monitoring. The STCC4 measures true CO2 using a thermal conductivity method rather than estimating from VOCs, and the onboard SHT41 helps improve the CO2 measuremen...
