For most CNC keypad models like the SK150 or XY series, short press the 'V-SET' button, then rotate the encoder knob to select the desired voltage. Pressing the knob usually sets the value.
Most EC Buying development boards use standard USB-to-Serial chips. Depending on the specific model, you may need to download drivers for the CP210x or CH340 chipsets from the respective chip manufacturer's website.
For Bluetooth amplifier modules like the ZK-502L, power cycling the device often resolves connection issues. Ensure no other devices are currently paired to the board before attempting a new connection.
