Hardware Specification
Pin-out
WizFi-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, GPIO4, GPIO5, GPIO6, GPIO7, GPIO20 are connected to WizFi360 inside the board. These pins enable UART communication with WizFi360 to use Wi-Fi function. If you are using the Wi-Fi function, these pins cannot be used for any other purpose.
The RP2040 GPIO used inside WizFi360-EVB-Pico is as follows.
| I/O | Pin Name | Description |
|---|---|---|
| O | GPIO4 | Connected to RXD1 on WizFi360 |
| I | GPIO5 | Connected to TXD1 on WizFi360 |
| O | GPIO6 | Connected to RTS1 on WizFi360 |
| I | GPIO7 | Connected to CTS1 on WizFi360 |
| O | GPIO20 | Connected to RST on WizFi360 |
| I | GPIO24 | VBUS sense - high if VBUS is present, else low |
| O | GPIO25 | Connected to user LED |
| I | GPIO29 | Used in ADC mode (ADC3) to measure VSYS/3 |
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 WizFi360), short this pin low. |
| PIN36 | 3V3 | Main 3.3V supply to RP2040 and WizFi360, generated by the on-board LDO. |
| PIN35 | ADC_VREF | ADC power supply (and reference) voltage, and is generated on WizFi360-EVB-Pico by filtering the 3.3V supply. |
| PIN33 | AGND | Ground reference for GPIO26-29. |
| PIN30 | RUN | RP2040 enable pin, To reset RP2040, short this pin low. |
Operation Condition
| Item | Description |
