V4.0 Development Board W/USB Serial Chip CP2102 +USB Cable
The processor core of Keyestudio V4.0 development board is ATMEGA328P-PU , fully compatible with ARDUINO UNO REV3.
The ESP32-WROOM-32 is a universal Wi-Fi+BT+BLE MCU module, with powerful functions; can be used in low power sensor networks. The core of this module is the ESP32-D0WDQ6 chip, which is scalable and adaptive. The two CPU cores can be individually controlled.
It has 14 digital input/output pins(of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, 1 ICSP header, and a reset button. The built-in ICSP port can burn the firmware for ATMEGA328P-PU directly. We can plug in power by USB wire, DC head and Vin GND pins.
