The keyestudio Leonardo is a microcontroller board based on the ATmega32u4 It has 20 digital input/output pins (of which 7 can be used as PWM outputs), 12 analog inputs, a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button. The Leonardo differs from other boards using separate USB-Serial chip in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard. Has fcc and ce certification that they are made from environmentally friendly production technology and materials, made function,voltage, current testing before packaging

AI & IoT Application: Pairing with block-based programming software mBlock, Halocode offers all sorts of opportunities to experience AI & IoT application with just a few clicks, like controlling home appliances in distance, AI speech recognition etc Support 60+ expansion parts: HaloCode can be expanded with more than 60 kinds of expansion accessories such as light sensor, soil moisture sensor and flame sensor, etc. Whether you are to make a smart light-sensitive curtain, a greenhouse ecosystem, or a fire alarm device, the external sensors can satisfy all the needs. From Scratch to Python: mBlock 5 is developed based on Scratch 3.0 supporting block-based programming. All that students need to do is dragging and dropping those color-coded blocks or switch to Python coding with just one click for advanced learning. Support Multiple Types of Power Supply and Connect: HaloCode can be powered via a Micro USB cable or AAA batteries (NOT Included), so you can use HaloCode anywhere, anytime. In addition to connecting with computer via USB cable, you also can use a Bluetooth dongle (Not included: B07G7NPYXW) to achieve wireless connection. Create Fun Projects Using both Hardware and Software: Halocode encourages students to use everyday items to create electronic projects. For example, they can design a video game through mBlock, then use Halocode to bridge both the game and any real objects as a joystick to control the game. Wielding hardware and software to an fun and educational ensemble to experience the wonders of electronic technologies.
