Evaluating a low-cost development board for an Arduino Uno-form-factor design? The Uno R3 CH340G ATmega328p Development Board Arduino covers the standard Uno feature set at a competitive price, listed at Rs 216 at Tech Depot India — order the Uno R3 CH340G ATmega328p Development Board Arduino for your next build or batch.
What is the Uno R3 CH340G ATmega328p Board?
Per the name, this is an Arduino Uno R3 form-factor development board built around the ATmega328p microcontroller, using the CH340G chip for USB-to-serial communication. That CH340G detail matters at the driver level — it's a different USB bridge than the ATmega16U2 used on genuine Arduino Uno boards, so on some systems you may need to install a CH340 driver separately before the board is recognized.
Beyond that USB-interface distinction, this board targets the same Uno-style development workflow — digital and analog I/O pins in the familiar Uno layout, programmable via the standard Arduino IDE. For confirmation of exact pin mapping and onboard regulator specs, refer to the product listing before finalizing your design.

Uno-compatible board options compared
| Product | Price | Notes |
|---|---|---|
| Uno R3 CH340G ATmega328p Development Board Arduino | Rs 216 | Uno R3 form-factor board with ATmega328p and CH340G USB chip |
| Ameba RTL8195 Arduino Wireless Board | Rs 2,028 | A wireless-capable Arduino-compatible board, a different class entirely |
| Arduino Decimilia Duemilanove compatible Board | Rs 896 | A compatible board based on the older Decimilia/Duemilanove design |
| Arduino Due AT91SAM3X8E ARM Cortex-M3 compatible Board | Rs 3,939 | A more powerful ARM Cortex-M3 based compatible board |
Choosing the right one for your project
If your project fits comfortably within the ATmega328p's memory and pin count, the Uno R3 CH340G board is the economical choice, particularly for batch or lab deployments where per-unit cost matters. If your design instead needs onboard wireless connectivity, a board like the Ameba RTL8195 is worth evaluating on its own merits rather than trying to add a shield to this one. And if you're pushing into higher processing demands than an 8-bit AVR can comfortably handle, an ARM Cortex-M3-based compatible board is the more appropriate direction. Match the board to your project's actual pin count, memory and processing requirements rather than defaulting to whichever is cheapest.
