Brand New Dual ESP32-C3 ez Share Bridge

Mule & Miner

Compact dual-WiFi bridge that turns any ez Share SD card into a network-accessible device — stream CPAP therapy data, offload SD card files, or build your own SD card transport layer. USB-C powered via two ESP32-C3s in a 3D-printed enclosure.

⚡ Mains-powered via USB-C only — contains no battery, no lithium cells, and no rechargeable components.

What It Does

The ez Share Wi-Fi SD card adapter creates its own isolated Wi-Fi access point inside whatever device it's plugged into. Your home network has no visibility into it.

The Mule & Miner sits on your network, connects to that ez Share AP, and forwards the data over your LAN via HTTP or MQTT — on a configurable polling interval. Plug it in, provision it once via captive portal, and it runs headlessly from then on.

Now with dual Wi-Fi and O2Ring oximetry support — stream SpO₂ and heart rate alongside your CPAP therapy data to CpapDash.

Known Applications
CPAP Therapy Monitoring
ResMed machines (AirSense 10/11, AirCurve 10) or any other model that writes session data to the SD card. The Mule & Miner makes that data available on your network in real time while you sleep.
SD Card File Offload
Any device using an ez Share adapter can have its files automatically forwarded to a NAS or local server without removing the card.
General ez Share Network Bridge
Any device with an ez Share SD card inserted becomes network-accessible. What you do with the data is up to you.
Build Your Own Transport Layer

The Mule & Miner isn't limited to the applications listed above. It exposes the ez Share file system over HTTP on your local network — any software that can make HTTP requests can pull files from the SD card on a schedule.

Use it as the transport layer for any project that needs wireless access to SD card data: IoT sensor logging, 3D printer monitoring, industrial data collection, or anything else that writes to an SD card.

No battery. No lithium cells. No rechargeable components. This device requires USB-C mains power only and is safe for international shipping.
