RP2350A USB Mini Development Board

This small development board uses the RP2350 chip with a dual-core Arm Cortex M33 processor and dual-core Hazard3 RISC-V processor running up to 150Mhz. There's 2MB of flash memory, a USB-C connector for programming and power and a USB Type-A 2.0 connector that supports a USB host or device via PIO.

There are 15 GPIO pins to easily connect to a Raspberry Pi Pico, and plenty of connectors including SPI, I2C, UART and 12-bit ADC. There is also support for C/C++ and Arduino IDE, with resources and tutorials to help get you started!
