Using the RP2040 microcontroller chip officially designed for Equipped with a dual-core ARM M0+ processor running at up to 133MHz flexible clock. Built-in 264KB SRAM and 2MB on-chip Flash Adopt Type-C interface, keep up with the trend of , no need to worry about the positive and negative plug. Onboard a 1.28-inch LCD display All GPIO (30 in total, but some pins have been connected to the internal bu circuit, you need to pay attention when multiplexing, please refer to the details) through the 1.27 pitch female header USB1.1 host and device support Supports low power sleep and hibernate modes Drag-and-drop program download via USB recognition as mass storage 2 SPI, 2 I2C, 2 UART, 4 12-bit ADC, 16 controllable PWM channels Accurate on-chip clocks and Temperature Sensor On-chip accelerated floating-point library 8 programmable I/O (PIO) state machines for custom peripheral support The on-board lithium battery charging and discharging interface is beneficial for the RP2040-LCD-1.28 to be used in some mobile scenarios.. RP2404-LCD-1.28 is a high-performance microcontroller development board. In the case of a small board, it is equipped with a 1.28inch LCD, a lithium battery charging chip, a six-axis sensor (three-axis acceleration and three-axis gyro) Instrument) and other peripherals, and lead out all GPIO and Debug interfaces, which are convenient for users to develop and embed into products. Material: PCB colour: blue Package Contents: 1 x RP2040 development board circular LCD module Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
