Further reading

Please refer to the following resources for more information:

• At this stage, it is worth having the datasheet for Raspberry Pi Pico to hand, available at https://datasheets.raspberrypi.org/pico/pico-datasheet.pdf. It has a helpful pin reference on page 5.
• CircuitPython also has a reference guide at https://docs.circuitpython.org/en/7.3.x/docs/index.html. The Core Modules section will be helpful for further experimenting with this environment.
