For Raspberry Pi 2 RP2350B 2.1-Inch LCD Round Touch Display QMI8658 Curved Surface leírása

The RP2350 2.1-inch circular touchscreen development board integrates an RGB display interface, an I2C touch interface, and multiple peripheral interfaces.
This product is a self-designed, high-performance, and highly integrated microcontroller development board. In a compact form factor, it features a 2.1-inch capacitive high-definition IPS screen, a six-axis sensor (three-axis accelerometer and three-axis gyroscope), an RTC, and a Micro- card slot, facilitating development and integration into products.
The RP2350B microcontroller chip, designed for Raspberry Pi, features a unique dual-core, dual-architecture design, incorporating a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V processor, both operating at clock frequencies to 150MHz, allowing users to flexibly between the two architectures.
It includes 520KB of and 16MB of -chip Flash, with a reserved PSRAM interface using a Type-C connector, eliminating the need for reversible insertion.
It features an onboard 2.1-inch capacitive touchscreen HD IPS display with a 480 x 480 resolution and 65K color depth, capable of clearly displaying color images. It supports USB 1.1 host and slave devices. It supports low-power sleep and hibernation modes. It can be recognized via USB for drag-and-drop program downloading to a mass storage device. Nine versatile GPIO pins are provided. Pinout:

2 SPI, 2 I2C, 2 UART, 5 12-bit ADCs, and 9 controllable PWM channels
Precise -chip clock and timers
Temperature sensor
-chip accelerated floating-point library
12 programmable I/O (PIO) state machines for custom peripheral support
Application Scenarios:
HMI (Human Machine Interface): A human machine interface (HMI) is the medium for interaction and information exchange between a system and a user. It enables the conversion between the int
