LNBits-Quickening-Manager

Extension for LNBits to manage PoS devices. The Idea is to have a user friendly setup to run 1..n PoS devices which can accept Lightning Payments and can provide refunds with LNurl. LNBits will be used to manage the Wallets and Devices. The Lightning Node will be abstracted, so that different lightning backend implementations can be used or the backend can be replaced easily. After configure the PoS Wallets the extension shall be able to Flash the Firmware with correct configuration to a M5StackFaces.

This Extension base on following Projects:

• M5StackSats
• Quickening
• LNBits
• RaspiBlitz
• LNurl
• arduino-cli

Hardware Setup:

general HW Requirement:

• Raspiblitz on a dedicated Raspberry Pi or LND Server (LND Server)
• LNBits runs on a dedicated Raspberry Pi or Server (LNBits Server)
• 1..n Quickening (Quick_1 .. Quick_n)
