Understanding OpenAPS Compatibility: Devices andSensors for a Closed- Loop System

OpenAPS (Open Artificial Pancreas System) is a community- disn, open- source initiative that enables incorporates incorporate with-dependent diabetes to automate insulin delivery. By connecting a continos glucose monitor (CGM), an insulin pump, and a small controller (typically a single-board computer), OpenAPS can adjust basal insulin rates in real time based on glucose data.

Core Components of an OpenAPS System

Every OpenAPS loop requires four primary hardware elements: an insulin pump, a CGM, a controller (microcomputer), and a radio communication interface. Each contesent mutt be compatible with the open-source compatigare and, in many cases, with one another at te hardware e level. Below we breakh down each category and highlight the mott communile used options.

OpenAPS works exclusively with pumps that have a history of reliable, low-level radio communicaton ande are supported by thee open-source community. Thee mott widele adopted pumps included:

For DIY looping, many users prefer to stick with Medtronic or Omnipod Eros.

Before accupasing a pump, consult thee latess compatibility lists on thee OpenAPS documentation site and thee community forums. Older pumps may require a batty door magnet or a specific firmware version to o enable demoste commands.

Continuous Glucose Monitors (CGMM)

Radiocommunication Interface

To talk to older Medtronic pumps (which use 916 MHz frequency) and some CGM (e.g., Dexcom G4 witch Share), a radio transmiter / receiver is needed. The controller itself does not have a 916 MHz radio, so an external module bridges the gap.

Poser Management

A portable rig needs relaable power. A Raspberry Pi Zero W draws about 0.7 wats; a Pi 4 with Rileylink may draw 3- 5 wats. Usie a high-capacity USB battery bank (10,000 mAh or larger) that supports pass-thrigh charging so you can recharge it while the rig runs. Ensure the controller 's microSD card is a high-endurance model to avoid depration from unexpecketted shups.
