SiFive Learn Inventor is a RISC-V educational board partially inspired by BBC Micro:bit board with the same crocodile clip-friendly edge connector, and an LED matrix.
The board is also fully qualified to work with the Amazon freertos-os/” rel=”category tag”>FreeRTOS real-time operating system.
Shaped in the form of a hand, the board features SiFive FE310 RISC-V processor found in risc-v-processor-wifi-bluetooth-esp32-module/”>the SiFive HiFive1 board, as well as ESP-WROOM-32 WiFi + Bluetooth module.
SiFive Learn Inventor specifications:
SoC – SiFive FE310-G003 32-bit RISC-V (RV32IMAFC) processor @ 150 MHz with 64KB of internal SRAM
Storage – 512 KB flash
“Display” – 6×8 “widescreen” array of RGB LEDs with 262,000 colors each; LEDs can expand off-board onto external arrays via the edge connector
Wireless Connectivity – 802.11b/g/n WiFi 4 (2.4GHz) and Bluetooth 4.2 LE via an ESP32 module (ESP-WROOM-32)
USB – 1x Micro USB port for power and programming/debugging
Expansion A/D Converters (four) accessed via on-board coprocessor BBC Micro:bit compatible edge connector with I2C, SPI, UART, GPIO, 3.3V, and GND signals
Sensors – eCompass module with 3-axis acceleration and magnetometer, ambient light sensor, thermometer accurate to 1°C over -40° to +85°C range
Misc – Real-Time Clock, two user push-buttons, hard reset button
Power Supply 5V via micro USB port Battery operation via 3x AA batteries (recommended) Low power operation is enabled through multiple power domains and a low-power standby mode
Certifications – RoHS / CaProp 65 / WEEE / REACH / EPEAT.
SiFive Learn Inventor runs open-source software with support for FreeRTOS, MicroPython and an SDK all free to download.
However, at this stage, I could only find source code and documentation for FreeRTOS sifive/Amazon-FreeRTOS”>on Github, as well as on an AWS page.
Programming can be done via a simple drag-and-drop interface over via USB, WiFi, or Bluetooth
