Product Introduction

Setting Introduction

1. PD Vset – PD Protocol Request Voltage: Adjustable from 8–24 V, 0.1 V step. Setting takes effect only when output is disabled. (V1.0.1.0 and above)
2. Brightness – Brightness: Adjustable from 0–100%; 0–10% corresponds to ultra-low brightness.
3. Reverse Dis – Reverse Display: 0 = Normal, 1 = 180° rotation. Setting takes effect after power cycle.
4. OCP Enable – Over-Current Protection: 0 = Disabled, 1 = Enabled. Output shuts down after approximately 200 ms when current exceeds the set value.
5. OC Discharge – Over-Current Discharge: 0 = Disabled, 1 = Enabled. (V1.0.0.2 and above)
6. AUTO OUT – Auto Output: 0 = Disabled, 1 = Enabled. Output automatically enables after power-on.
7. Filter.Win – Output Filter Window: Adjustable from 1–200, default value 50. (V1.0.0.3 and above)
8. Output Comp – Output Compensation: 0 = Disabled, 1 = Enabled. (V1.0.0.5 and above)
9. UART Mode – UART Mode: 0 = Disabled, 1 = Enabled. Setting takes effect after power cycle. (V1.0.0.5 and above)
10. UART Baudrate – UART Baudrate: 0-6, respectively corresponding to 9600, 19200, 38400, 57600, 115200, 230400, 460800. (V1.0.0.5 and above)
11. Factory Reset – Factory Reset: Set to 1 and exit the settings menu to restore factory defaults (calibration values will not be cleared).
12. Offset Enable – Calibration Enable: 0 = Disabled, 1 = Enabled. Factory default is 1 (calibrated).

UART pins are assigned to DP and DM of Type‑C connector: DP → TX, DM → RX, 3.3 V logic level.
Note: The external UART chip must feature reverse-current protection (e.g., CH340K) to prevent power backfeeding and PDPowerMiniV1 startup failure when the UART side is powered up first.
