Happy New year to everyone and welcome to the first update of 2025! We hope you had a great holiday season and are ready to start the new year with a bang. We have some updates on the production of the Healthypi Move and some changes we have had to make to the design.

Design Changes

In the last update, we decribed the final enclosure for the Healthypi Move and how things are coming together. However, we did mention that one of the key sensors called the Analog Devices MAXM86146 had suddenly become very elusive and Analog Devices had seemingly stopped production of it, according to Mouser (both Mouser and Digikey cancelled our backorders after four months of waiting), despite the fact that it was a recently released chip. Analog Devices, strangely, seems to list it as active, but the MOQ seems to be 5000!

Long story short, we have redesigned the board to replace this chip with three separate chips, while keeping the size and performance the same. This has been a bit of a setback for us, but we are marching ahead with production in full swing. Unfortunately, this has pushed the production timeline by one more month and we are now looking at a March, 2025 delivery. We intend to finish our final testing by mid-February, after which we would ship to Mouser and they would sent them out to everyone. We are working hard to make sure this is the last delay and we are sorry for the inconvenience caused.

Here are some pictures of the old board design (v5) compared with the new board design (v7) with the extra chips.

The highlighted red areas show the new chips that have been added to the board, while the one in the first photo is the MAXM86146 that has been removed. One of the main advantages and the main reason we chose the MAXM86146 was the fact that it has the photodiode + analog front-end + sensor hub (with the algorithms) in the same, small package. This made it very easy to integrate into our design. However, the new design has an OSRAM module ingrating two photodiodes and four LEDs, the MAX86141 for the analog front-end and the MAX32664 for the sensor hub. This has increased the complexity of the design and the sensor board has also now become a six-layer board instead of a four-layer board, but we get the same, if not better performance.

Production Progress

We are now in the middle of production of the new sensor boards, with the main boards already completed. We have also received the new clear enclosures we mentioned in the last update and have started 3D printing the new chassis for the device.

Once again, we are sorry for the delay, but we do hope that you understand this was a sudden change that was beyond our control. We do not expect any more delays since we now have all the parts in hand and are working hard to get the devices assembled and shipped out to you.

Thank you for your continued support and patience.
