Adjustable DC Power
Remote voltage and current control — the power supply becomes a command
Connects over BLE to adjustable buck power modules (XY6509 / SK200W and similar) to set output voltage and current limits remotely, read back measured values, operating mode (CV/CC) and protection status in real time, and plot voltage and current curves.
The adapter layer isolates model differences: the write characteristic is identical while the notification characteristic is detected per model; all readings are restored using fixed-point scaling so no firmware version can introduce an order-of-magnitude error. A simulation mode lets you walk through the whole flow without hardware.

Mode, output and protection states read back live.
Dual curves
Independent voltage and current ranges that expand automatically.
Simulation mode
Demo and develop without hardware.

- In simulation mode every reading is synthetic and the UI marks it in red — never use it to judge real circuit behaviour.
