# Meshimi (BegoonLab)

> An open-hardware LoRa and Wi-Fi 6 module that plugs into a Flipper Zero for Meshtastic and LoRaWAN.

- **Category:** Radio & mesh
- **Availability:** Availability unconfirmed
- **Good for:** Add LoRa mesh radio to a Flipper Zero.
- **You'll need:** A Flipper Zero and a LoRa antenna for your region.
- **Trade-off:** Only a demo Flipper app is published; flashing steps are unfinished.
