Keyestudio PLUS Development Board with Type C interface +USB cable compatible with Arduino Uno R3

1.Description

Doing experiments with electronic products, we often program on the Arduino IDE development environment with Arduino series microcontrollers.

Keyestudio PLUS control board is fully compatible with Arduino IDE development environment. It is as same as the Arduino UNO R3 board. Moreover, some improvements we made highly strengthen its function(as shown below). In order to wire efficiently, we equip it with a 1m USB cable with type-c interface for you.
