A compact, low-cost development board built around the Raspberry Pi RP2350 microcontroller, with a 2.8" 240x320 IPS display, 5-point capacitive touch, built-in IMU, LiPo charging and more!
At its core of this dev board is an RP2350 - a dual-core ARM Cortex-M33 and dual-core Hazard3 RISC-V processor design, running at up to 150 MHz with 520KB of SRAM. Waveshare have also added 16MB of onboard flash memory to open this up to more projects.
The capacitive touch panel connects via I2C and supports 5-point touch and interrupts for responsive UI control.
It includes a QMI8658 6-axisaccelerometerandgyroscope sensor, speaker outputs with amplifier (speakers included!), RTC, slot for a MicroSD card and PicoBlade/MX1.25 battery charge management circuit. It also supports USB device/host functionality, drag-and-drop programming via USB mass storage, and flexible expansion via GPIO, UART, and I2C (Qwiic-style connector) interfaces. Multiple power modes and a flexible clock system allow for low power consumption in various scenarios.
The board comes with a pair of mini 8Ω 2W speakers and jumper assembly cables.
