Board Pinout
( J1 ) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | VIN | Voltage Input Pin (1.8V ~ 5.5V) |
(J2) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | VIN SENSE | Can be used to measure the input voltage directly on the input capacitor. |
(J3) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | HIGH | Power Supply |
| 2 | EN | Shorting jumper between the center pin EN and HIGH turns on the unit. Shorting jumper between the center pin EN and LOW turns the unit off. (Default: Pulled up to VIN in circuit) |
| 3 | LOW | Ground |
( J4 ) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | VOUT SENSE | Can be used to measure the output voltage directly on the output capacitor. |
( J5 ) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | HIGH | Power Supply |
| 2 | PS/SYNC | The center pin of this jumpers is connected to the SYNC pin of the TPS63030 and is used to synchronize the unit with an external clock.This jumper also enables/disables the power-saving mode at light loads. To enable power-save, PS/SYNC must shorting to LOW. (Default: Pulled up to VIN in circuit) |
| 3 | LOW | Ground |
( J6 ) Pin Number
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | GND | Ground |
| 2 | VOUT | Buck-boost converter output (3.3V) |
