Qwiic RED-V RedBoard - evaluation kit with SiFive RISC-V Freedom E310 microcontroller

Description

Evaluation kit with SiFive Freedom E310 microcontroller with RISC-V (ISA) architecture. The board contains the SiFive Freedom E310 core (works with a frequency of 150 MHz), 32 MB QSPI flash memory, NXP K22 ARM Cortex-M4 microcontroller for USB operation and as a JTAG interface and Qwiic connector. It is equipped with a USB Type-C connector. The SiFive Freedom E310 microcontroller offers a debug module, flexible clock generation with built-in oscillators and PLL, and a wide range of peripherals including UART, QSPI, PWM and timers. The kit is programmed using Freedom Studio or the Zephyr RTOS compilation environment (these environments do not yet have support in the form of Qwiic libraries). The board has dimensions and pin spacing compatible with Arduino Uno R3. There is a user guide on the product page.
