Circuit Documentation

Summary

This document provides a detailed overview of a circuit that integrates a Raspberry Pi Pico microcontroller with a China ST7735S 160x128 display module. The Raspberry Pi Pico is responsible for controlling the display module, which is capable of showing graphics and text. The circuit connections are established to power the display, control its backlight, and facilitate communication between the microcontroller and the display via SPI (Serial Peripheral Interface).
