Raspberry Pi Pico Development Board A Low-Cost High-Performance Microcontroller

Introducition:

The Raspberry Pi Pico is a microcontroller board based on the Raspberry Pi RP2040 microcontroller . It has been designed to be a low-cost, high-performance microcontroller board with flexible digital interfaces. The Raspberry Pi Pico features two ARM Cortex-M0+ cores run up to 133MHz; 256KB RAM; 30 GPIO pins; and a broad range of interfacing options. This is paired with 2MB of onboard QFlash memory for code and data storage.

In addition to powerful hardware resources, Pico has rich and complete software support and community resources. It comes with a complete Rasberry Pi official C/C++ SDK, Micropython SDK. Just click "https://pico.raspberrypi.org/getting-started" to get started with Raspberry Pi Pico.

Pico has been designed to use either soldered 0.1" pin-headers (it is one 0.1" pitch wider than a standard 40-pin DIP package) or can be used as a surface-mountable 'module', as the user IO pins are also castellated. There are SMT pads underneath the USB connector and BOOTSEL on, which allow these signals to be acceed if used as a reflow soldered SMT module.

Specification:

• RP2040 microcontroller designed by Raspberry Pi in the United Kingdom

• Dual-core Arm Cortex M0+ proceor, flexible clock running up to 133 MHz

• 264KB of SRAM, and 2MB of on-board Flash memory

• Castellated module allows soldering direct to carrier boards

• USB 1.1 with device and host support

• Low-power sleep and dormant modes

• Drag-and-drop programming using ma storage over USB

• 26 × multi-function GPIO pins

• 2 ×, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels

• Accurate clock and timer on-

• Temperature r

• Accelerated floating-point libraries on-

• 8 × Programmable I/O (PIO) statehines for custom peripheral support

Product description

RP2040 Microproceor (MCU) integrates dual-core ARM architecture Cotex-MO+ core, directly integrates 264KB RAM, supports up to 16M Qexternal expansion Flash, highly flexible I/O settings, including l2C,, PIO ( Programmable I/O); YD-RP2040 core board is a core board circuit board made of RP2040 microproceor (MCU), which is convenient for users to carry out peripheral expansion, circuit design and construction. Raspberry Pi has also launched its own official RP2040 core board, the model is Raspberry Pi Pico core board, YD-RP2040 core board, which can achieve no recognition result with Ra core in terms of mechanical size and electrical pins. The board is compatible for use, see the information for details on the differences, and improve a series of deficiencies of the Raspberry PiPico core board:

●Increased the PWR power indicator to improve the human-computer interaction experience when plugged into the USB power supply.

●Change the microUSB interface of Raspberry Pi Pico to Type-C of YD-RP2040 core board, the USB interface is convenient for users to find related USB cables more conveniently.

●Add a reset on, which is convenient for users to reset and update firmware in the power-on state.

●Add USRkey user on, which is convenient for users to verify and use simple input functions.

●Added RGB light group, which is convenient for users to operate the RGB light group to reflect various information through the on-off and brightne of red, green and blue lights.

Pin introduction：

Hardware introduction：

Update firmware operation proce

■Pre and hold the BOOT on on the board, do not release it, keep preing it; first, connect the computer and the core board with the USB cable of the type-C interface.

■Pre and hold the BOOT on on the board, do not release it, keep preing it;

Pre the RST on again;

■Release the BOOT on after 1 second;

The computer will be automatically recognized as a removable hard disk;

■Copy the file to be downloaded (burned) to the removable hard disk that appears, and the core board will restart automatically.
