The RP2350B microcontroller chip is designed using a Raspberry Pi architecture. It features a unique dual-core, dual-architecture design, equipped with a dual-core ARM Cortex-M33 processor and a dual-core Hazard3 RISC-V processor, both running at clock frequencies up to 150MHz, allowing users to flexibly switch between the two architectures. It has 520KB of built-in SRAM, 16MB of on-board Flash memory, and 2MB of PSRAM. It uses a Type-C interface, eliminating the need to worry about correct plug orientation. It features an on-board 4.3-inch LCD capacitive touchscreen with an 800x480 resolution and 65K colors. Due to different batches, there may be differences in product appearance and printed text, which will not affect use. Color: As Shown Material: ABS+LCD Package Contents: 1*RP2350-Touch-LCD-4.3B-BOX
