1) Will the 5v relay modules you sell be suitable for switching directly from the sensor shield / Uno board ? Yes, this is exactly what they are designed for. Depending on the relay module you choose they either have an transistor or opto-isolator interface that means there is very little load plac...

Thanks for the feedback. If your are referring to the two jumpers that select between I2C and serial, your board should have come with them fitted and in the I2C position. I'm not sure why yours hasn't got them but I guess the factory must have forget to add them and we didn't spot it. Let us know i...

Hi andyedtec, Although we just spoke offline I just want to reply for the benefit of other forum users: For the library you need to use the library form the first post called ethercard-master.zip This is the latest version and should compile on fine for V1.0.6 of the Arduino IDE. I can also confirm ...

Thanks for highlighting this. I've added a note to the first post to point this out. If you can't use them at that range don't forget we do accept unwanted items back. Just send an email sales at hobbycomponents .com

The up to 15 CM spec comes from the manufacture and I would suspect the range is dependent on the sensitivity of the tags used. Especially passive ones. Normally with an RFID reader you wouldn't want a good range because for example you don't wan't it reading a tag in the pocket of a person walking ...

what is the difference between the P1 and P2 sets of pins? Nothing, they are electrically connected together. The additional header is probably just there to make it convenient to daisy-chain other I2C devices on the same bus. The significant different is that one header has the addition of the SQ ...

The panel isn't an open source product so I'm afraid schematics and source code aren't available. It does however come with an English manual showing how to program it. I'll be uploading another image to the first post shortly that will show the innards. That will give you a better idea of what's in...

Yeah its in the list! We also plan to stock the larger display too.

Good spot I'll get a note added to the first post.

http://hobbycomponents.com/images/forum/HCDVBD0025_800_600.JPG http://hobbycomponents.com/images/forum/forum/Description.png This tiny and low cost AVR development board is great for compact projects or projects that only requires a few IO pins. Based on the 8 pin Atmel ATTiny85 processor it allows...
