Review on 🔌 KeeYees 3 Set ATmega328P CH340 Microcontroller Development Board with USB Cable and Jumper Wires by Jeremy Adams

None of the three were recognized by the computer. I think I need the same LINK that the seller gave D. Bolton. An internet search yielded no such information on this UN board. Update: Googled the Windows CH340 driver and found it. Installed and now all three boards are working as expected. To test the boards I used the MD_Max72xx example sketch with 4 red 8x8 matrix chips. The first launch failed (I don't know why), but because that first launch failed, all subsequent launches went perfectly. The board ran flawlessly with the MAX7219 matrix kit. I ran the same test on both my Windows 10 system and Windows 07 system. Both needed the CH340 driver to work. I recommend that you download the latest Arduino IDE software before attempting to upload a sketch. lance
