RP2040 Raspberry Pi Core Board Compatible With RP2 Raspberry Pi Pico Micropython YD-RP2040 4MB /16MB modname=ckeditor RP2040 Microprocessor (MCU) integrates dual-core ARM architecture Cotex-MO+ core, directly integrates 264KB RAM, supports up to 16M QSPI external expansion Flash, highly flexible I/O settings, including l2C, SPI, PIO ( Programmable I/O); YD-RP2040 core board is a core board circuit board made of RP2040 microprocessor (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 button, which is convenient for users to reset and update firmware in the power-on state. Add USRkey user button, which is convenient for users to verify and use simple input functions.
