The Uno R3 CH340G ATmega328p Development Board is the low-cost version of the popular Uno R3 Arduino. It is assembled with the CH340 USB to Serial converter chip, instead of using an Atmega16U2 chip. We have used plenty of these low-cost Arduino boards with CH340 chips, and have found them to work perfectly. The only time the CH340 chip is used is during programming and when using the serial output of the USB port. During normal operation, this board is identical to the more expensive version without CH340 chip.

Almost one and half-year before Raspberry Pi Foundation had launched a revolutionary update on their Single Board Computer (SBC) Pi 3 and become the most popular Microcontroller board in the community which is known as a Raspberry Pi 4. On the same timeline, the Raspberry Pi Foundation came with a new astonishing SBC named Raspberry Pi Pico. The main highlighted thing about RPi Pico is the Lowest cost and Smallest size development board from Raspberry Pi Foundation ever. On the technical side, it is equipped with an RP2040 Microcontroller chip developed by Raspberry Pi Foundation itself. RP2040 is their first dual-core ARM Cortex M0+ processor-based latest small-sized, budget-friendly microcontroller. RP2040 Microcontroller chip The RP2040 is supported with both C/C++ and micro-python, meaning that if you’re a beginner and want to learn any of these languages, the Raspberry Pico would be the best product option to start with. https://robu.in/product/raspberry-pi-pico/
