Ads1298 breakout board

I am working on a project using bio potential signals to control a prosthetic arm and I want to incorporate an ADS1298 with an arduino nano but I need to find a breakout board for the ads1298 but don’t see anything listed. Please assist

Welcome to the forum.

Haven’t seen any pre-made boards but you could have this open source design PCB made and build yourself one.

Hello @michael.jason.dol,

Have you considered boards such as this?

Another excellent starting point is the evaluation board:

Best wishes,

Hi, PCB3006-1 looks like exactly what I need. How does the ads1298 get secured to the board?
Could it order the board with the ads1298 surface mounted on it already?

Hello @michael.jason.dol,

You would need to purchase the 64-TQFP package:

It can be soldered by hand as shown in this video. Recommend you practice with a less expensive devices to get the hang of soldering.

Sincerely,

Aaron

You can also look at the PA0096-ND board. If you do not want to solder the ADS1298 chip, you can use a programming adapter, like AC164413-ND which is a lot higher cost.

Thank you @David_1768,

That’s a breadboard friendly solution!

Cordially,

Note that this is a high-end chip designed to work with very low-level signals. Don’t expect optimal results with one of these adapter boards.

Proper layout is very important for noise suppression, and the long traces required for break-out boards are susceptible to picking up noise. Bypass capacitors are generally recommended to be placed close to the supply and reference pins for good performance and there is no provision for these on any of the break-out boards.

Pages 98-99 of the datasheet cover some of the recommended layout guidelines.

For good performance without having to lay out your own board, the ADS1298ECGFE-PDK evaluation board that @APDahlen mentioned above would be a good option.

Good point, @David_1528.

Reverse engineering the OEM’s development board provides a good starting point.

It’s possible to add those bypass capacitor to the board but it’s fussy work with a high probability of shorting things out. For a $0.50 part, I’d say give it a try. For a $30.00 part, not so much.

Cordially,

Aaron
