Highly Functional Arduino Board

This Arduino board is an excellent addition to my garage. Thanks to my knowledge gained in practice, I can say that it is a high-quality product. It is very easy to use and has several features that make it stand out from other Arduino boards on the market. The compact design of the board is a plus as it does not take up much space. However, the only downside to this product is that it may be a little expensive for beginners. Overall, it is a great investment for anyone looking to upgrade their

Pros
  • Provides an easy and efficient way to control one channel with the Duemilanove MEGA2560 or MEGA1280 boards
Cons
  • Only controls one channel, limiting its versatility and usefulness for more complex projects

Does what it says on the tin

Accepts a low power (only a few milliamps) 6-12 VDC signal to turn on the SSR. Works very well. A lot of people give bad reviews because they abuse boards.

Pros
  • Easy to use
Cons
  • Quick Start Guide

Resistance too high.

I bought this relay to replace a mechanical relay as the bounce prevents the digital circuitry from meeting monotonous turn-on specifications. I'm just switching 5V into a digital circuit of about 500mA, but the relay resistance is too high and the output voltage is only 4.2V. I even applied 5V directly to the inputs. Still not good. The data sheet of the digital relay itself states a maximum output voltage drop of 1.6V, I can only tolerate 0.1V.

Pros
  • Decent performance
Cons
  • Miscellaneous Miscellaneous
