Mitayi-Pico-D1

<![CDATA[]]>Mitayi-Pico-D1<![CDATA[]]> is the first development board from CIRCUITSTATE Electronics. The board is based on the RP2040 microcontroller from Raspberry Pi and is designed after the official <![CDATA[]]>Raspberry Pi Pico<![CDATA[]]> board, but adds a few improvements over it. D1 is the first design variant of Mitayi-Pico. Mitayi-Pico is not pin-compatible with the official Raspberry Pi Pico. The schematic and PCB are designed with KiCad, an open-source EDA tool. All the design files of Mitayi-Pico are completely open-source and released under the MIT license.

Features & Differences


RP2040 dual-core, 133MHz ARM Cortex M0+ microcontroller.
Up to 16 MB Flash memory in SOIC-8 package.
USB-C for power and communication.
USB solder pads.
MIC5219 LDO with 3.3V, 500 mA output.
Power indication LED.
RESET button.
BOOTSEL button reconfigurable as GPIO input button.
Debug LED with GPIO solder jumper.
Breaks out all MCU GPIO pins.
EXP8 expansion connector in 2x4 2.54mm pin header. Breaks out SPI, UART and I2C.
