RP2040-Touch-LCD-1.28 Development Board 1.28 Inch Round Capacitive Touch LCD 240x240 IPS Display 65K RGB Colors Dual-Core Arm Cortex M0+ Processor 6-Axis Sensor USB Type-C

Product Description:

RP2040-Touch-LCD-1.28 development board with a compact 1.28-inch round capacitive touch display, 6-axis motion sensor, lithium battery recharge and discharge header, and dual-core microcontroller architecture. It is designed for smart device development, embedded projects, and human-computer interaction applications.

Core Selling Points:

The onboard round IPS touch display supports 240 x 240 resolution and 65K colors for interactive interfaces. A 3-axis accelerometer and 3-axis gyroscope provide 6-axis motion sensing. The dual-core Arm Cortex M0+ processor runs at up to 133 MHz, while USB 1.1 device and host support, drag-and-drop USB programming, low-power sleep and dormant modes, and a Type-C connector support development and integration. The board also includes a temperature sensor, accurate on-chip clock and timer, and six GPIO pins through an SH 1.0 connector.
