Arduino projects and devices
Arduino hardware in Flashable covers three distinct jobs. UNO R4 WiFi pairs a Renesas main controller with an ESP32-S3 bridge and built-in 12×8 matrix, supporting matrix animations as well as advanced bridge-firmware maintenance. Nano ESP32 is the compact wireless option for either Arduino sketches or a replacement MicroPython runtime, and it can host Matter examples when core, partitions, pins, and commissioning setup match. Nicla Vision is the camera-and-sensor choice for OpenMV development and Edge Impulse image classification. These workflows are not interchangeable: MicroPython overwrites Nano firmware, OpenMV can be replaced by Arduino uploads, and Nicla models must fit internal flash. Follow each device into original project sources, compatible firmware and practical guides.
