Pico Primer kit

About the product

Introduce

This kit is designed for MicroPython learning with raspberry pi PICO. The kit includes the main board and some modules of the Mabee series ( Servo, Slide potentiometer, DHT11 sensor, Relay, MPU6050, ESP8266, Ultrasonic Ranging). The mainboard base on the Pico and LCD display, features three buttons, three LEDs and a buzzer. It also provides six interfaces to connect the peripheral modules.
