3.8 GPIO Pads/Battery Status Indication Pads (J205)
The Ethernet to Wi-Fi® Bridge Board features GPIO pads (J205) that provide access to the GPIO pins of the WFI32E01PE. These pads enable users to interface with the WFI32E01PE for custom applications, such as monitoring battery voltage and status indications, tailored to specific user requirements.
| Pin Number | Pin on J205 | Pin Definition of Battery Status Indication Pads (J205) | Pin on WFI32E01PE |
|---|---|---|---|
| 1 | RB9 | nPowerGood | INT3/RPB9 |
| 2 | RB7 | STAT1/LBO | INT1/RPB7 |
| 3 | RB8 | STAT2 | INT4/RPB8 |
| 4 | RA11 | VBAT_SENSE_EN | RA11/RPA11 |
| 5 | RA13 | VBAT_SENSE | ANN1/RPA13 |
| 6 | GND | GND | GND |
A voltage divider circuit is provided to the VBAT_SENSE pin for sensing the battery voltage level of 3.7V.
