## Power

### Voltage-Level Config

3 configs available:

|          |   3.3V    |    1.8 with LDO     |         1.8V without LDO          |

| -------- | :-------: | :-----------------: | :-------------------------------: |

| VIN Typ. |   3.3V    | (VDD + 0.2V) ~ 5.5V |               1.8V                |

| VIN Max. |   3.6V    |        5.5V         |               2.1V                |

| JP1      | `[1-2 3]` |      `[1 2-3]`      |             `[1-2-3]`             |

| Note     |           |                     | `U2`, `R4`, `C3~5` can be omitted |

### Jumper

| JP1 Config |                     | Description                  |

| :--------: | ------------------- | ---------------------------- |

| `[1-2 3]`  | 2 and 1 close, 3 NC | VIO = VIN                    |

| `[1 2-3]`  | 2 and 3 close, 1 NC | VIO = VDD (i.e. LDO output)  |

| `[1-2-3]`  | 1, 2 and 3 close    | VIO = VDD = VIN (LDO bypass) |

### Operating Voltage Range

- **VDD**: 1.8 ~ 2.1V (i.e. LDO Vout)

- **VIO**: VDD ~ 3.6V (i.e. VDDIO)

- **VIN**: Depends on [Voltage-Level config](#voltage-level-config)
