{"product_id":"sparkfun-hifive1-rev-b","title":"SparkFun HiFive1 Rev B","description":"\u003cp\u003eSince the launch of the original HiFive1 and the FE310 in 2016, we have received lots of great community feedback. The FE310-G002 is an upgrade to the Freedom Everywhere SoC, that adds support for the latest RISC-V Debug Spec 0.13, hardware I²C, two UARTs, and power gating the core rail in low power sleep modes. Like the original FE310, the FE310-G002 features SiFive�s E31 CPU core complex, a high-performance, 32-bit RV32IMAC core with a 16 KB L1 instruction cache, a 16 KB data SRAM scratchpad, and hardware multiply\/divide. Running at 320+ MHz, the FE310 is among the fastest microcontrollers on the market.\u003c\/p\u003e \u003cp\u003eThe HiFive1 dev board has also been upgraded. Powered by the FE310-G002, the new HiFive1 Rev B has wireless connectivity through an onboard Wi-Fi\/Bluetooth module. The USB debugger has been upgraded to Segger J-Link, with support for drag \u0026amp; drop code download. In favor of driving GPIO directly from the FE310, the HiFive1 Rev B supports 3.3 V I\/O only.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eCPU: SiFive E31\u003c\/li\u003e \u003cli\u003eRISC-V Debug Spec: version 0.13\u003c\/li\u003e \u003cli\u003eLow-power Sleep Mode: Yes\u003c\/li\u003e \u003cli\u003eAlways-on Domain: 3.3V\u003c\/li\u003e \u003cli\u003eHardware I\u003csup\u003e2\u003c\/sup\u003eC: 1\u003c\/li\u003e \u003cli\u003eUART: 2\u003c\/li\u003e \u003cli\u003eQSPI\/SPI: 1\/1 with 3 chip selects\u003c\/li\u003e \u003cli\u003ePWM: 9\u003c\/li\u003e \u003cli\u003eGPIO: 19\u003c\/li\u003e \u003cli\u003eRF Frequency: 320 MHz\u003c\/li\u003e \u003cli\u003eData Bus Width: 32 bit\u003c\/li\u003e \u003cli\u003eProcessor: SiFive FE310-G002\u003c\/li\u003e \u003cli\u003eUSB Debug: Segger J-Link\u003c\/li\u003e \u003cli\u003eWireless Network: Wi-Fi \u0026amp; Bluetooth\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eExamples:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.crowdsupply.com\/sifive\/hifive1-rev-b\/updates\/led-pendulum-demo\"\u003eLED Pendulum Demo\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40331927617621,"sku":"16438:DEV-16438:spark","price":11465.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/16438_-_HiFive1_Rev_B_1.jpg?v=1663614382","url":"https:\/\/www.tanotis.com\/products\/sparkfun-hifive1-rev-b","provider":"Tanotis","version":"1.0","type":"link"}
