The Waveshare RP2350-USB-A Mini Development Board is an ultra-compact microcontroller platform built around the Raspberry Pi RP2350A dual-core (ARM Cortex-M33 / Hazard3 RISC-V @ 150MHz) MCU. Featuring 520KB SRAM, 2MB NOR Flash, a USB Type-C connector, and an integrated USB Type-A port driven via PIO state machines, it provides versatile host and device connectivity. Designed with castellated edges for direct SMD mounting, 15 multi-function GPIOs, drag-and-drop mass-storage flashing, and C/C++/Arduino IDE support, it’s an ideal choice for space-constrained custom electronics and embedded USB peripherals.
The ESP32-S3-Touch-LCD-4.3B is an all-in-one HMI development board featuring a 4.3-inch 800×480 IPS capacitive touch display driven by an ESP32-S3 dual-core LX7 microcontroller (240MHz). Equipped with 16MB Flash and 8MB PSRAM, it easily powers advanced GUIs like LVGL. Built for industrial applications, it incorporates isolated Digital I/O, CAN, RS485, I2C, TF card storage, RTC, and a wide-range 7–36V DC power supply with battery fallback. Flexible screw terminal options make integration into DIN-rail setups or custom enclosures effortless.
