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 on a configurable polling interval. Plug it in, provision it once via captive portal, and it runs headlessly from then on.
This kit includes everything — bridge, adapter, and SD card. Nothing else to buy.
Now with dual Wi-Fi and O2Ring oximetry support — stream SpO₂ and heart rate alongside your CPAP therapy data to CpapDash.

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.
Power & Shipping
No battery. No lithium cells. No rechargeable components. This device requires USB-C mains power only and is safe for international shipping without any battery-related restrictions.
