CrowdSupply刚刚启动了一个众筹项目-一个名为Precursor的便携式开源RISC-VSoC开发套件，该套件分别使用了Xilinx和Lattice的两种流行的FPGA。从外部看，它看起来像一部智能手机。它声称通过编程，您可以真正将其用作智能手机或平板电脑，并且可以对其进行完全控制，因为您可以对其进行编程。一点点陷入硬件的底部！套件的正面照片和背面照片均被拆卸，并由以下部分组成：电路板，单色LCD屏幕，键盘，查看键盘的电路板：内部结构：高度安全且完全值得信赖。从下面的比较表中，您可以看到其主要功能：与其他FPGA开发板进行比较：价格高是有原因的。下面是一个结构图：特征：MadefordevelopersNoadhesivesholdingthebezelsinplace-justonescrewdriverisallittakesWanttoaddhardware Maybeacellularmodem Noproblem BatterycompartmentisablankcheckforyourperipheralsInstallasmallerbatteryformorespaceFlexPCBbreakoutfor8xFPGAGPIOintothebatterycompartmentBezelismadeoutofFR-4，andcanbeuser-customizedtoholdadditionalcomponentsInspect，modifyandcompileyourSoCandembeddedcontrollerfromsourceAllsourcefileshostedonGitHubforconvenientfork，pullrequest，andissuetrackingOpensourcePCBandcasedesignEasy-accessdeveloper＆安培; ＃39; scable（包括）低级调试（GDB + Chipscope）和通过开发人员＆amp;固件刷新＃39 ??！ ;！scablepluggedintoacustomRaspberryPiHAT（包括）MiddlewaredebuggingviaUSBcableviawishbonetunnelOpensourcetothecoreExtendableandmodifiableSlimandlightmobileformfactor6063alloyaluminumcase - 3Dfilesprovided，soyoucanmillyourowncase -FR-4mmfrontbezelmandmmmx96 d174gramsAccessiblemechanicaldesignUser-customizableCPUsManagespower，待机，andchargingfunctionsTestedwith18MHzVexRISC-V，RV32I，非缓存-L1speedgradeforlongerbatterylifeTestedwith100MHzVexRISC-V，RV32IMAC + MMU，4kL1I / DcacheXilinxXC7S50primarySystemonChip（SoC）的FPGAiCE40UP5KsecondaryEmbeddedController（EC）FPGA16MBexternalSRAM128MBFlash100MHzDDR8-快速XIP代码性能的位宽总线双硬件TRNG基于SoC振荡器的TRNG物理键盘，具有可更换布局的可重复叠加的LCD 200ppi黑白LCD（336x536分辨率），可通过标准光学显微镜进行100％检查，夜间可使用模块化键盘PCB，带安全的集成式触摸屏，带触摸屏的音频，默认键盘可插拔ed0.7WspeakerfornotificationsVibrationmotor3.5mmheadsetjackNointegratedmicrophone - audiosurveillanceisnotpossiblewhenheadsetisunpluggedIntegratedWi-FiSandboxedinahardware-delineateduntrusteddomainSiliconLabsWF200CoversetUSBType-CoversetUSBType-CovertoSupportsvoltagecharging lerantto20VPowernegotiationto5V@1.5A（sourceandsink）SupportslegacyUSB2.0full-speedPHYBasicDRPnegotiationhardwaresupport1100mAhLi-IonbatteryApprox.100hoursstandbywithWi网络连接+ embeddedcontroller + staticdisplayenabledApprox.700mW＆QUOT;接通状态＆QUOT; （mostfeaturesenabledandactive，backlightoff）powerdraw，or5.5hourscontinuoususeIntegratedgasgaugeformoreaccuratebatterylifeestimateFullchargeinaboutthreehoursRuntimedependsonuserapplicationAnti-tamperfeaturesUser-sealablemetalcanfortrustedcomponentsDedicatedreal-时钟进度（RTC）withbasicclockintegritymonitoringPowermonitorstripresetincaseofpowerglitchesAlways- onaccelerometer / gyrotodetectmovementinstandbySupportforinstantsecureeraseviabattery-backedAESkeyandself-destructcircuit
