KEYESTUDIO V4.0 Development Board ATmega328P for Arduino UNO R3 with USB Cable

Please Note this keyestudio development board replaced with the USB-to--Serial CP2102 driver. It works perfectly as a typical Arduino R3 board, but a little bit different from the USB serial chip. Here is the tutorial link for setting it up with a Mac. https://www.dropbox.com/sh/a5og0zte5l0mdq3/AAAHnv8v5qrMKoZWn4Vv1GXTa?dl=0 How to install the driver of CP2101 on MacOS system? 1.Download the driver of CP2102 https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers 2.Download the Mac_OSX_VCP_Driver https://www.dropbox.com/sh/9mhd8kog3hm4l2t/AADTL-4GxzOIO_5Y1iAYBgr8a?dl=0 Description: It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin/ GND(DC 7-12V) to get started.
