Features: Brand new and high quality RP2040 microcontroller chip designed independently for Raspberry Pi. Dual core ARM Cortex MO+processor with a flexible clock running at frequencies up to 133MHz. Built in 264KB SRAM and 16MB on-chip Flash onboard DVI interface, capable of driving the vast majority of HDMI screens (compatible with DVI interface) onboard PIO-USB interface, can serve as USB host and slaveOn board Micro SD card holder, readable and writable Micro SD card on board lithium battery charging and discharging interface, which is beneficial for use in mobile scenarios. USB 1.1 host and device support can be recognized as mass storage through USB for drag and drop download. The program supports low-power sleep and sleep modes, including 2 SPIs, 2 I2Cs, 2 UARTs, 4 12-bit ADCs, and 16 controllable PWM channels. Accurate on-chip clock and timer temperature sensors. On chip acceleration floating-point library with 8 programmable/0 (PIO) state machines, used for customized peripheral support. The development board has a unique open shell cover made of acrylic material, which can clearly see the technology behind the machine. The shell is transparent and easy to install. Insert the PI into the bottom, connect the fan and clamp it on the top for easy connection to all ports and maximum airflow. The acrylic plate on the top can be opened upwards for more convenient use. Specifications: Material: PCB+Acrylic Size: 66x34x19mm Note: No retail package.
