keyestudio UNO with pin header interface is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller
keyestudio nano ch340 controller is a small, complete board based on the ATmega328. It’s a open source Simple I/O platform with 12 Digital I/O Pins (of which 6 provide PWM output), 8 Analog Input Pins, pin 0 (RX) and 1 (TX) used to receive (RX) and transmit (TX) TTL serial data, a Mini-B USB connection, an ICSP header and a reset button.
The processor core of the EASY plug Control board V2.0 Control board is ATmega328.
Development board IO port with crystal head leads, and couples with power supply interface can allows you to connect external sensors and module with a line, so you don't worry that the wrong wiring will damage the external wiring products.
The keyestudio Leonardo R3 development board is our newest easy-to-use open-source controller.It has twenty-three digital I/O ports, seven PWM ports and twelve analog input ports.Compared with other versions of Arduino using separate USB - Serial conversion chips,it only uses a single Atmega32u4 to achieve USB communication and control.The Atmega32u4's native support USB feature also enables Leonardo to simulate a mouse and keyboard.
Keyestudio PRO MICRO development board is compatible with all Arduino skills, including four analog inputs, five PWM pins, twelve digital inputs/outputs and hardware serial port Rx and Tx. Its operating voltage is 3.3V and working frequency is 8MHz, which can accept external supply voltage up to DC 16V.
