Hardware Specification

Pin-out

WizFi360-EVB-Pico_Pinout_220405

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/OPin NameDescription
OGPIO4Connected to RXD1 on WizFi360
IGPIO5Connected to TXD1 on WizFi360
OGPIO6Connected to RTS1 on WizFi360
IGPIO7Connected to CTS1 on WizFi360
OGPIO20Connected to RST on WizFi360
IGPIO24VBUS sense - high if VBUS is present, else low
OGPIO25Connected to user LED
IGPIO29Used 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 NameDescription
PIN40VBUSMicro-USB input voltage, connected to micro-USB port pin 1. Nominally 5V.
PIN39VSYSMain 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 .
PIN373V3_ENConnects to the on-board LDO enable pin. To disable the 3.3V (which also de-powers the RP2040 and W5100S), short this pin low.
PIN363V3Main 3.3V supply to RP2040 and W5100S, generated by the on-board LDO.
PIN35ADC_VREFADC power supply (and reference) voltage, and is generated on W5100S-EVB-Pico by filtering the 3.3V supply.
PIN33AGNDGround reference for GPIO26-29.
PIN30RUNRP2040 enable pin, To reset RP2040, short this pin low.
