Keyestudio V4.0 Development Board W/USB Serial Chip CP2102 +USB Cable

The Keyestudio V4.0 Development Board is a highly reliable microcontroller board fully compatible with the Arduino Uno Rev3, featuring an upgraded CP2102 USB serial chip. It is an ideal choice for South African students, educators, and makers looking to build stable electronics and coding projects. This complete kit includes the development board and a USB cable to get you started immediately.

Arduino Uno Rev3 compatibility

Built around the ATmega328P-PU microcontroller core, this board offers seamless compatibility with the Arduino Uno Rev3 platform and software. It runs at a clock speed of 16 MHz and includes a built-in LED connected to pin D13.

Flexible power input options

You can power the board easily using a USB cable, the onboard DC power jack, or via the Vin and GND pins. The recommended input voltage through the DC jack is 7V to 12V, operating internally at 5V.

Versatile digital and analogue pins

The board features 14 digital input/output pins and 6 analogue inputs from A0 to A5. Six of the digital pins can be configured to provide PWM outputs for controlling motors or LEDs.

Stable CP2102 USB serial communication

Equipped with a high-quality CP2102 USB-to-serial converter chip, this board ensures stable and reliable communication with your computer. It allows for hassle-free programming and serial debugging via the included USB cable.

Direct firmware burning via ICSP

An onboard ICSP header allows you to burn firmware directly to the ATmega328P-PU microcontroller. This is highly useful for advanced users and educators who want to bypass the bootloader or program the chip directly.

Onboard memory and storage

The ATmega328P-PU microcontroller provides 32 KB of flash memory for storing your code, with 0.5 KB reserved for the bootloader. It also includes 2 KB of SRAM and 1 KB of EEPROM for data storage.
