DIY 2.4G Expreless PWM 5通道迷你接收機
1.硬體的話網上有資料，這裡著重研究軟體，怎麼去燒錄
首先只要Python執行命令安裝PIO外掛，不用VS開發環境
2.串列埠升級，接收機進入升機模式
把接收機當高頻頭用 pio run -e DIY_2400_TX_ESP8285_SX1280_via_UART -t upload
[env:DIY_2400_TX_ESP8285_SX1280_via_UART]
upload_port = com27
monitor_port = com27
monitor_speed = 115200
5通道刷機命令 pio run -e DIY_2400_RX_PWMP_via_UART -t upload
[env:DIY_2400_RX_PWMP_via_UART]
upload_port = com27
monitor_port = com27
monitor_speed = 115200
