230V single phase wattmeter, voltmeter, ammeter, mains frequency, power factor and active power meter. Communication over TTL UART using Modbus-RTU protocol.

Universal coin holder with the possibility of setting up to 6 different types of coins. Impulse output.

USB-C PD/QC power voltage switch

HLK-V01-KIT-V2.0 is an offline voice recognition module.

Water level monitor with contacts that can directly control the load with relays.

The controller uses PWM (Pulse Width Modulation), which uses changes in the width of the current pulse to the motor. In pulse control, the current and voltage remain the same,...
