Dual Core Processor: Equipped with a dual-core ARM Cortex M0+ processor, the operating frequency is up to 133MHz flexible clock, built-in 264KB SRAM and 4MB on-chip Flash. 1.8A Switch: Built-in lithium battery charging and discharging interface, built-in DC DC chip TPS63000, 1.8A switch high-efficiency DC DC step-down voltage boost chip, 8 programmable IO/(PIO) state machines, for custom peripheral support. 26 Multifunction Pins: Up to 26 multifunctional GPIO pins, 2 SPI, 2 12C, 2 UART, 3 12-bit ADC, 16 controllable PWM channels. Precise on-chip clocks and timers, temperature sensor, on-chip accelerated floating-point library. Type C Interface: The development board uses the RP2040 microcontroller chip designed by the official Raspberry Pi, and the Type C interface must be entangled front and back. Low Power Consumption: Supports low power consumption in sleep and dormant modes, and can be recognized as mass storage via USB for drag-and-drop program downloads. The stamp hole design can be welded directly and integrated into the bottom plate designed by the user. Item Type: Development Board Material: PCB Main Chip: RP2040 Microcontroller chip independently developed for Raspberry Pi Voltage Regulator Chip: TPS63000 USB: Type C Flash: 4MB Lithium Battery Port: Support (under charging and discharging) 1 x Development Board
