Arduino Uno vs. Seeeduino v4.2 - Comparison of Two Microcontroller Boards with USB Host Capability
If you're in the market for a microcontroller board with USB host capability, you have probably come across the Arduino Uno and the Seeeduino v4.2. Both these boards offer great functionality at a reasonable price. But which one should you go for? In this blog post, we will compare these two boards to help you make the best choice.
Size and Design
One of the most evident differences between the Arduino Uno and the Seeeduino v4.2 is their size. The Arduino Uno is a bit larger than the Seeeduino v4.2, measuring 68.6mm x 53.4mm compared to the Seeeduino's 75mm x 65mm. The Seeeduino v4.2 has a more compact design that could make it easier to fit into smaller projects.
Performance and Memory
When it comes to performance, both boards perform similarly. Both use the ATmega328P microcontroller, and thus have the same 32KB flash memory and 2KB SRAM. However, the Seeeduino v4.2 stands out with an additional 16MHz secondary crystal oscillator that allows it to perform better in applications that require precise timing.
Connectivity
Both the Arduino Uno and Seeeduino v4.2 have USB Type-B connectors for programming and powering the board. Additionally, both boards have 14 digital input/output pins and six analog inputs. However, the Seeeduino v4.2 has an advantage over the Arduino Uno in its connectivity options. It comes with an additional USB host port that allows it to connect to other USB devices directly.
Price
The Arduino Uno is widely available and is priced at around $23, while the Seeeduino v4.2 can be purchased for around $8 more, priced at $31. However, the Seeeduino v4.2 does include a few more features, such as the additional crystal oscillator and the USB host port.
Conclusion
In conclusion, both the Arduino Uno and Seeeduino v4.2 are great microcontroller boards with USB host capability. They have similarities but also have some differences. Selecting a board will ultimately come down to your specific needs and preferences. If you need more connectivity options and a more compact design, the Seeeduino v4.2 might be the better choice for you. If you are looking for a more cost-effective option with standard features, the Arduino Uno could be a better option.
