Hardware Specification
Pin-out v1.0
PIN-OUT IMAGE COMMING SOON
W6300-EVB-Pico pinout is directly connected to the GPIO of RP2040 as shown in the picture above. It has the same pinout as the Raspberry Pi Pico board. However, GPIO15, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21, GPIO22 are connected to W6300 inside the board. These pins enable QSPI communication with W6300 to use the Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.
The RP2040 GPIO used inside W6300-EVB-Pico is as follows.
| I/O | Pin Name | Description |
|---|---|---|
| O | GPIO15 | Connected to INTn on W6300 |
| O | GPIO16 | Connected to CSn on W6300 |
| O | GPIO17 | Connected to SCLK on W6300 |
| I/O | GPIO18 | Connected to IO0 (MOSI) on W6300 (QSPI) |
| I/O | GPIO19 | Connected to IO1 (MISO) on W6300 (QSPI) |

Apart from GPIO and ground pins, there are 7 other pins on the main 40-pin interface:
| Pin No. | Pin Name | Description |
|---|---|---|
| PIN40 | VBUS | Micro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V. |
| PIN39 | VSYS | Main system input voltage, which can vary in the allowed range 4.3V to 5.5V, and is used by the on-board LDO to generate the 3.3V . |
| PIN37 | 3V3_EN | Connects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2040 and W6300), short this pin low. |
| PIN36 | 3V3 | Main 3.3V supply to RP2040 and W6300, generated by the on-board LDO. |
