I have added the boards to Tindie for anyone who wants them. The design is generic to any of the MAX3010x series modules, so we will sell all versions. The design we made is pretty minimal compared to Sparkfun's MAX30105 and others. The MAX3010x series is 6V pin tolerant, so much of the i2c bus wrangling is unnecessary.

I am also looking at using something like the TPS8268180, though it is a little pricey it may be easier to build with by hand compared to the LM3671TL series BGA.

The photos aren't great, I will have a new camera and light box configuration soon:

Hi, just wanted to let everyone know that Maxim Integrated has released a small reference design board for the new MAX30102 complete with examples:

MAXREFDES117

I will be updating this design, but just to make a Flex Module compatible version. I hope this design will help everyone interested.

I have rejected a bunch of random request to join this project. If you are not a bot and are truly interested in working on the software issues, please let me know. Do not just click the join button.

If you want to generally help on making small wearable circuit designs, I would suggest talking to me about joining the general Flex Modules project.

We are still waiting for parts to confirm if the reference design appears to work.

It may take some effort to create them, the datasheet is pretty minimal and there isn't that much information public about the module.

PPG is not recommended to be measured on the wrist. There are many consumer fitness products that do try, but movement disturbs the reading. This module is tiny, so maybe it can be placed tight against the wrist.

For this component we had to sign an NDA. We will develop drivers, but I am concerned about exposing what Maxim believes is its intellectual property. I have no idea how their position helps them sell more components.
