1. 源由

在《Open FPV VTX开源之硬件规格及组成》章节中，已经基本介绍了产品组成。

为了让其正常工作，其组合大致有以下几种方式：

Open FPV VTX + Ardupilot
Open FPV VTX + betaflight
Open FPV VTX + inav
Open FPV VTX + PX4 //个人来说，用的比较少

为了让其正常工作，在第一次上电之前需要做一些准备工作，本章就是为了这些准备工作编写的。

2. 连线

2.1 飞控

Open FPV VTX  -- toFC -- Flight ControllertoFC:- pin1: VCC(7.4~26V)  ---- FC VBat+- pin2: GND  ------------- FC GND- pin3: UART_RX1  -------- FC OSD_TX1- pin4: UART_TX1  -------- FC OSD_RX1- pin5: GND  ------------- FC GND- pin6: NC

注：选择笔者第一台FPV无人机使用的Holybro Kakute F7 and KAKUTE F7 AIO串口1作为OSD的UART。

2.2 调试

由于DEBUG线是预先做好的，这里就不一一对应做连接，直接从逻辑上进行示意。

Open FPV VTX  -- toDebug --  GND/UART_TX0/UART_RX0 --  USB -- PC Serial Console|+------  TP_LAN/TN_LAN/RP_LAN/RN_LAN  -- Ethernet  -- PC SSHtoDebug:pin1: TP_LANpin2: TN_LANpin3: RP_LANpin4: RN_LANpin5: GNDpin6: UART_TX0pin7: UART_RX0

3. serial

serial环境就是类似PC的BIOS阶段，主要用于低层次升级固件版本，可能会导致变砖。若真的变砖就需要其他JTAG工具，比如：J-Link。

在这里插入图片描述
注：调试版通常情况下串口驱动是默认的，请仔细查看驱动是否正确安装。
