• Description
• The Raspberry Pi Pico is a low-cost, high-performance microcontroller board with flexible digital interfaces. It feature the RP2040 which marks Raspberry Pi's first microcontroller designed in-ho***. Pico provides minimal(yet flexible)external circuitry to support the RP2040 chip(Flash, crystal, power supplies and decoupling and USB connector). The majority of the RP2040 microcontroller pins are brought to the ***r IO pins on the left and right edge of the board. Four RP2040 IO are ***d for internal functions - driving an LED, on-board Switched Mode Power Supply(SMPS)power control and sensing the system voltages.
• Pico ***s an on-board buck-boost SMPS which is able to generate the required 3.3 volts(to power RP2040 and externalcircuitry)from a wide range of input voltages(~1.8 to 5.5V). This allows significant flexibility in powering the unit from various sources such as a single Lithium-Ion cell, or 3 AA cells in series. Battery chargers can also be very easily integrated with the Pico powerchain. Reprogramming the Pico's flash memory can be done using USB(simply drag and drop a file onto the Pico which appears as a mass storage device)or via the Serial Wire Debug(SWD)port. The SWD port can also be ***d to interactively debug coderunning on the RP2040
• Pico has been designed to *** either soldered 0.1" pin-headers(it is one 0.1" pitch wider than a standard 40-pin DIP package)or can be ***d as a surface mountable "module," as the ***r IO pins are also castellated. There are SMT pads underneath the USB connector and BOOTSEL button, which allow these signals to be accessed if ***d as a reflow-soldered SMT module.
