The Pico (Program In Chip Out, Electronics) RP2040 Board by ADIY FLY is their first microcontroller, featuring a robust dual-core processor, extensive on-chip memory, and a unique Programmable I/O (PIO) subsystem. This provides unmatched capability and versatility for professionals. ADIY PICO With Ethernet is a microcontroller evaluation board based on the Raspberry Pi RP2040 and fully hardwired TCP/IP controller W5500 – and works the same as the Raspberry Pi Pico board but with additional Ethernet via W5500.

The board is a cost-effective and adaptable development platform tailored for the RP2040. It’s designed to be as pin-compatible as the Raspberry Pi Pico. At its core, it operates on a dual-core Arm Cortex-M0+ processor, capable of speeds up to 133 MHz, and boasts a generous 264KB on-chip SRAM. It’s paired with 4MB Flash memory and supports 3.3-5.5V inputs. The board offers 27 GPIO pins, with four serving as analog inputs, positioned on 2.54mm through-hole pads. A RESET button ensures user-friendliness. Manufactured using a 40nm process, the RP2040 ensures high performance and efficient power usage, ideal for battery operations.

Its built-in direct memory access (DMA) controller, accelerated on-chip integer and floating-point libraries, and drag-and-drop programming via USB simplifies the development process. A precise on-chip clock, temperature sensor, and 8 programmable I/O state machines enhance its customizability.

The chip, integrated with WIZnet technology, is a dedicated Internet controller encompassing a full hardwired TCP/IP stack. It facilitates internet access to embedded devices using SPI (Serial Peripheral Interface). It shares the same pin configuration as the Raspberry Pi Pico board. While its GPIO pins enable SPI communication for ethernet functionality, they become dedicated for this purpose, making them unavailable for other tasks. 

The board offers 8 distinct sockets for simultaneous use and a 32KB internal memory dedicated to data communication. This allows developers to easily craft ethernet applications using the board’s straightforward socket programming rather than navigating a multifaceted ethernet controller.  The ADIY Fly’s notable quality, affordability, and availability are complemented by its uncomplicated yet versatile power supply system, allowing for multiple power options, from micro-USB to batteries.
