Adopts for RP2040 chip with rich expansion libraries for better playability. Dual-core ARM CortexMO+ processor, running frequency up to 133MHz. On-board high-current step-down chip TPS63000, higher conversion efficiency, more stable power supply, current up to 1.8A. Pin definition and Pico the same. On-board 32Mbit high-capacity FLASH chip; on-chip temperature sensor Can be downloaded via USB debugging program, support MicroPython programming. with 2 SPI, 2 IIC, 2 UART, 4 12-bit ADC and other interfaces, powerful. Instructions for use: Configure the MicroPython environment of the development board First, press and hold the BOOT button of the development board, and then plug in the USB connection cable. At this time, the computer will show an additional disk drive. Open the USB flash drive, drag in the UF2 file "rp2-pico-20220618-v1.19.1.uf2", after the file is written, the USB flash drive will disappear, open the device manager, you will find that there is a new port. At this point, the board can support MicroPython programming, if you need other programming methods, you need to drag and drop different UF2 files into the boot mode, please refer to WIKl. Configure MicroPython environment Unzip "Thonny-3.3.3.zip" in the "Development Tools" directory, double click it to run the program. Click "NEXT" to install the program. After the installation is complete, open the software, and in "Tools" - "Settings", select the device as PICO and the port as the port of the development board. in this way, you can download and debug the board online. size: 51mm x 33mm Material: PCB colour: As shown Package Contents: 1 x for RP2040 Development Board 2 x 20 Single Pin Header Only the above package content, other products are not included.
