    The ADIY Uno R3 CH340C ATmega328P Development Robust Board is the low-cost version of the popular UNO R3 Arduino.

    ADIY UNO is a microcontroller board based on the ATmega328P. Instead of ATmega16U2 processor, it is assembled with CH340C IC. t 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; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started.

    ADIY FLY Pico RP2040 is the debut microcontroller-class board from ADIY

    ADIY FLY comes with a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set augmented with a unique Programmable I/O (PIO) subsystem, RP2040 provides professional users with unrivalled power and flexibility. ADIY FLY pairs RP2040 with 4MB of Flash memory, and a power supply chip supporting input voltages from 1.8-5.5V. It provides 27 GPIO pins, three of which can function as analogue inputs, on 0.1”-pitch through-hole pads. The RESET button on ADIY FLY makes the usage of module easy.

    RP2040 is manufactured on a modern 40nm process node, delivering high performance, low dynamic power consumption, and low leakage, with a variety of low-power modes to support extended-duration operation on battery power.
