The first task is to copy the required libraries from the CircuitPython folder stored on a computer to the lib folder on the CIRCUITPY drive.įor the ESP32 the following library folders and.

TXO - Not needed for Wifi - Used for Blutooth.

RXI - Not needed for Wifi - Used for Blutooth.

GP0 - Not needed - used for Bootloading and Blutooth.

3v Out - upto 50ma for other devices (not used).

Vin 3.3v - 5v - 250ma required for WiFi use.

For this guide these are the connections to the Pico. Any required libraries should be copied to the lib folder. Once the Pico has the firmware installed and a usb cable is plugged into a computer, there will be a new drive on your computer called CIRCUITPY. In addition the libraries will need to be downloaded to a computer which you use to transfer the required libraries to the Pico as you need them. I'm using CircuitPython, you can find the firmware for the Pico here The firmware needs to be installed to use the chosen version so the Pico can only be setup with one or the other. These are both supplied in firmware that is installed to the Pico which means you have to set the Pico up with one or the other language.įor Python programs the Pico can be setup with Micropython or CircuitPython.

For this guide I will go through how to setup the Pico with a WiFi connection using CircuitPython.įor writing scripts in Python the Pico can use either Micropython or CircuitPython.

I have the ESP32spi which can communicate with WiFi or Bluetooth and uses a SPI connection to connect to the Pico. The ESP32 is a complete module which handles all the wifi connectivity leaving the Pico just to handle the data that is being transmitted. The other option is to get a ESP32 WiFi co-processor.

The Raspberry Pi Pico RP2040 micro controller is a good option for projects but if you need wifi connectivity you will need to use a different micro controller with WiFi or you can make you project with a Raspberry Pi Zero or RPi4. With an example of sending data with MQTT.
