Arduino Leonardo R3The Arduino Leonardo is a microcontroller board based on the ATmega32U4 SMD chip that is open source. It has a 16 MHz crystal, a USB connection, a power jack, an in circuit system programming (ICSP) header, and a reset button. It has 20 digital input output pins (of which 7 can be used as PWM outputs and 12 can be used as analog inputs), a 16 MHz crystal, a USB connection, a power jack, an ICSP header, and a reset button. It comes with everything

9mm Length 5 meters Operating Temperature -25°C to +80°C

This is a Right Angle SMA Connector Female

It's a 70mm Robot Car Wheel for BO Motors

The LM35 is a precision IC temperature sensor with a proportional output to temperature (in degrees Celsius)

Auto blink for activity/signal indication without additional circuit

MQ-7 is a sensor that detects CO levels in the air

it may also appear as a mouse and keyboard to a connected computer

All setting parameters are automatically saved after power off
