ADS1299EEGFE-PDK: ADS1299EEGFE-PDK

Part Number: ADS1299EEGFE-PDK
Other Parts Discussed in Thread: ADS1299

Hello,

I'm starting using the ADS1299 Performance Demonstration Kit which is composed by the MMB0 board and the ADS1299EEG.

I received the box with these two components and without a specific power supply. The section 2.4 of the user manual mention (slau443b) that the kit includes only these two parts.

Very strangerly I found in the manual the first sentence of the paragraph 3.3 which says: 

Apply power to the MMB0 using the supplied wall mount power supply and connect the MMB0 to your PC
via any available USB port.

Why this sentence refers to a supplied power supply? It is quite confusing!

Anyhow, reading the specifications of the power supply on the manual I put a 6V - 1A commercial wall mount power supply in the main jack input after having controlled the proper polarity.

The boards don't start and, while the board is connected to the power supply, the input voltage drops to 2V. After removing the connection the input power supply continues to work.

Do you have any idea that would help me to work with the boards?

Please let me know if I can consider the board failing or if some further test are needed.

Thank you in advance,

BR,

Gionatan

  • Hi Gionatan,

    Thanks for your post and welcome to the forum! 

    I apologize for the confusion, we used to supply the wall jack as well but have since stopped doing so and we've been intending to update the user's guide but it is still in process. 

    Do you mean that the input voltage of the jack drops to 2V? That means it is most likely limited by the current, which is probably caused by some sort of short. 

    Can you provide a picture of your setup?

    Please check that the jumpers are in the default position and that the boards are properly connected. 

  • Dear Alex,

    thank you for your prompt reply. Thank you also for the explanation about a misleading sentence.

    Anyhow, I found that I was erroneously supplying 6V to the main input which is probably the absolute ratings limit and therefore some sort of protection was taking place.

    Now, setting a 5V input power supply, the board can be connected to the PC and I hope to start acquiring some signal in the next days. 

    Hoping to go on in a smooth way. In case I will ask some further assistance.

    Many thanks,

    GT
