rt1052v2's Introduction

RT1052V2

SphinxEVK是由SphinxEVK项目成员StackYuan设计的,基于I.MXRT1052系列MCU的核心板。板上关键信号(SDRAM, nor flash, sd card)均设计了等长,使用了4-layer,4mil/4mil(线宽/线间距),直径8mil/14mil(孔/带焊环)的生产工艺,可以被当前主流PCB打样厂生产。

注:

开发板设计了严格的上电时序和电源域,同时兼容RT1052 A0和A1版本。

为了减小体积,开发板使用78mil/2.00mm排针设计。如调试飞线感到不便,工程下也提供了标准100mil/2.54mm的IO拓展板:SphinxEVK_ExtIO.PcbDoc


板上资源:

1.预留QSPI nor flash/Hyperflash双焊盘

2.预留SDRAM焊盘

3.RGB565 CSI接口(异面兼容龙邱MT9V034)

4.RGB565 DSI接口

5.KSZ8081 ENET PHY

6.引出Micro USB(USB1)

7.引出UART(LPUART1)

8.引出SWD(带RST)

9.引出SDIO(TF slot)

10.引出所有非关键IO


勘误:

1.使用LQ神眼摄像头时,由于IIC线序错误,故使用软件IIC进行初始化

2.SD卡可能会出现枚举失败问题,原因是进入高速模式时,主芯片NVCC_SDIO脚不能完成3.3V->1.8V电压的切换。建议暂使用低速模式。

3.UART1 RXD未设置上拉,可能在进行ISP模式时由于RT的内部bootloader检测失误,造成USB下载模式不能进入。
