Recently, Huawei announced that it has released its first RISC-V development module that will allow designers to design and develop products using the RISC-V architecture. The new module, called the Hi3861, integrates a RISC-V core onto a module that is similar to the Adafruit Huzzah32 board.
The main controller of the board is the Hi3861 which includes a 32-bit RISC-V core clocked at 160MHz, 352KB SRAM, and 288KB ROM. The module also integrates a 2MB flash memory, and an integrated Wi-Fi controller with a maximum data rate of 72.2Mbps on the 2.4GHz spectrum. Peripherals integrated into the SoC include SDIO, SPI, I2C, GPIO, UART, ADC, PWM, and I2S.
The module itself uses a USB 3.0 connector and a CH340 USB to UART to provide a programming and communication interface. The use of two buttons provides a RESET input and user input for programming while two jumper caps are used for programming the onboard flash. To extend the capabilities of the module, a development board is also available that brings out the pins for use with OLEDs, NFC, extended antenna, and JTAG.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
