RP2040-LCD-0.99-B User Guide

【Overview】

[] RP2040 Microcontroller LCD Development Board: Designed based on Raspberry Pi's RP2040 with a CNC metal enclosure.

【Features】

RP2040-LCD-0.99-B is a high-performance and cost-effective microcontroller product designed by Waveshare, featuring a 0.99-inch circular LCD screen (with a non-arc-shaped bottom edge in the display area) and peripherals like a six-axis sensor (three-axis accelerometer and three-axis gyroscope). It integrates a Raspberry Pi-designed RP2040 microcontroller chip and exposes 4 GPIO pins through the SH1.0 6PIN connector, making it convenient for development and embedding into applications.

Key Features:

[] Uses the RP2040 microcontroller chip designed by Raspberry Pi

[] Equipped with dual-core ARM Cortex M0+ processor, running at a flexible clock frequency of up to 133MHz

[] Built-in 264KB SRAM and 2MB on-chip Flash

[] USB Type-C interface for modern connectivity, with reversible insertion

[] Onboard 0.99-inch 125x115 resolution, 65K color IPS LCD display (non-arc-shaped bottom edge in the display area) for clear color image display

[] Exposes 4 GPIO pins through the SH1.0 6PIN connector

[] CNC metal upper shell and acrylic matte bottom plate on the back

[] USB 1.1 host and device support

[] Supports low-power sleep and deep sleep modes

[] Recognizable as a high-capacity storage device for drag-and-drop program downloads via USB

[] 2 I2C, 4 12-bit ADC

[] Precise on-chip clock and timer

[] Temperature sensor

[] On-chip accelerated floating-point library

[] 8 programmable I/O (PIO) state machines for custom peripheral support

[] Supports C/C++, MicroPython, Arduino, with comprehensive SDK, open-source materials, and tutorials for easy integration into applications.
