HealthyPi is the first fully open-source, full-featured vital sign monitor. Using the Raspberry Pi as its computing and display platform, the HealthyPi add-on HAT turns the Raspberry Pi into a vital sign monitoring system.

Who Needs the HealthyPi?

Technical Specifications

Feature Highlights

Easy-to-use

The simple, highly integrated design of the HealthyPi results in ease of manufacturing, more reliability, and lower cost. Nonetheless, some of the analog chips used here are the same ones present in professional patient monitoring systems.

We have ensured that the entire system is easy to use, makes it easy to add features, easy to customize, and easy to reproduce too, if you wish. The PCB design itself is simple and the software design is simpler.

You can get as deep into the technical details of the HealthyPi as you want. Just want to use it as a data monitor? Perform the default install and you’re ready to start using it right away. Are you a serious software hacker trying to make the software more efficient and the algorithms more intelligent? You can do that too.

Flexible

The HealthyPi was designed with not just one application in mind, but a variety of them. While it does function as a vital sign monitor for traditional patient monitoring applications, it can also be used for several other applications. You can use it with a Raspberry Pi using a display; use it with a Raspberry Pi with the official touchscreen using our "Complete Kit," or you can use it standalone by connecting it to any computer’s USB port. The software is compatible across all platforms.

Ready for the Internet of Things

Utilizing the Raspberry Pi 3’s built-in WiFi and Bluetooth capability, the HealthyPi is ready to connect to the internet of things. This makes it very easy to get data into the cloud for any kind of analysis and/or decision-making. The built-in MQTT client in the processing GUI can send realtime vital signs data to any MQTT client/server with minimum overhead. Below is a screen-cap of the HealthyPi 3 sending data to an AWS EC2 instance running Thingsboard IoT platform.

Open Source Hardware

All the hardware schematics, layout, and BOM will be available on our Github repo soon after the campaign ends. This means you can modify, improve, and/or generally just hack the hardware. The hardware designs are all in Eagle, which makes it easily accessible and editable without spending a lot on expensive PCB design software. Also, unlike certain open source hardware, we don’t just give you the schematic, but the Eagle schematic, layout files and BOM. We make it easier for you to take our design and use it for your own.

Open Source Firmware

At the heart of the HealthyPi is the Atmel/Microchip ATSAMD21 microcontroller with an ARM Cortex M0 core. This is the same chip in the Arduino M0/Zero, which makes it automatically programmable with Arduino. You wrote a better algorithm for noise removal? Just edit the code to include the new program and upload it using the on-board USB port. If you want to skip using Arduino totally and just program the on-board processor directly with a JTAG programmer, there is also a JTAG header available. We will have the code for Atmel Studio 7 also.

Open Source GUI Software

Processing is a great piece of open-source software that allows you to create any kind of desktop application with Java code. Processing itself is open-source and also has several user-contributed libraries. The software is platform agnostic and works equally well on Windows/MacOS/Linux and, of course, Linux-ARM, which is on the Raspberry Pi.

What’s Included and What’s Required

Healthy Pi 3 HAT Kit includes:

Healthy Pi 3 Complete Kit includes:

If you wish to make changes to the Raspberry Pi code or connect the Raspberry Pi to your Wi-Fi network or anything else, you will need a keyboard and mouse which plugs into the Raspberry Pi. Touchscreen includes an on-screen keyboard also. If you wish to power your HealthyPi from a battery, you can use any standard USB power bank (NOT included) to power the system. We actually recommend the use of a power bank for providing power as it is safer and minimizes noise.

Powering up your HealthyPi

HealthyPi takes power from the 5 V power present on the Raspberry Pi’s 40-pin expansion header. Depending on your application, you can power your Raspberry Pi + HealthyPi in several ways:

Manufacturing Plan

We have our own assembly and testing facility for low volume (100 pcs) production. This includes a small pick-and-place machine, ovens, and microscope inspection equipment. We also have our own team with testing and inspection expertise at our office/assembly facility/warehouse in Bangalore, India.

All the components for this products are from authorized, well-known vendors, primarily Digi-Key and Texas Instruments. This includes even smaller components such as capacitors and resistors to ensure we get consistent signal quality and reproducibility of signals each time, every time.

We have already successfully manufactured and sold hundreds of HealthyPi v2 boards to customers all over the world. So, we are in the know about manufacturing challenges and system performance and can plan appropriately. HealthyPi v3 is a huge overhaul of our earlier versions and is more stable. We are already all set for the manufacturing run for the first 100 units.

Shipping & Fulfillment

All orders will be shipping from our office in Bangalore, India. We try to keep just enough inventory of components so that we can do quick assembly, while at the same time optimizing our manufacturing costs (because we don’t stock a lot of components at a time).

We have very preferential negotiated shipping rates with UPS Express and DHL Worldwide Express. For this reason, we are able to offer free shipping worldwide. All orders will be shipped using UPS or DHL (depending upon your location), and will be insured and trackable.

Customs import duty and taxes may apply for certain countries and certain customers. All the clearance procedures will be performed by the courier, but the customer is responsible for paying any import duties/taxes, if applicable.

Shipping Schedule

The first 100 units of the HealthyPi v3 (board only or complete kit) will be shipped about 10-12 days after the campaign end date. Orders received for additional units will ship within 24 days of the campaign end date. Since we have already manufactured and shipped several products, we are able to confidently give specific shipping schedules and stick to them. Also, the components used have a steady supply chain with active production and we’re confident of getting all of them at any given time.

Important Warning: Although this has all the features of a medical grade patient monitoring system, this does NOT have any certifications (FDA/CE/IEC) and is NOT approved for MEDICAL or diagnostic use. It is your responsibility to ensure your safety when using the device. Never power the device from an non-isolated power source.
