CLOUD SPEED.
HARDWARE POWER.
Run your front-of-house on a blazing Next.js web app. Connect ESC/POS thermal printers, barcode scanners, scales, and cash drawers with our hardened C# .NET Raspberry Pi agent. Works 100% offline and syncs seamlessly with the LeadsKE cloud.
HYBRID EDGE + CLOUD PIPELINE
The key architectural decision: Don't force the Raspberry Pi to run your entire stack. Let Next.js handle the cashier experience, while the .NET Agent controls physical hardware.
Tier 1: Cloud POS Platform
Tier 2: LeadsKE POS Agent (.NET / C#)
Tier 3: Supported Physical Peripherals
HARDWARE WITHOUT VENDOR LOCK-IN
The LeadsKE POS Agent turns a $35 Raspberry Pi into a robust hardware bridge. Drive commercial receipt printers, barcode scanners, cash drawers, and scales with open standards.
ESC/POS Thermal Receipt Printer
Sub-10ms High-Throughput Printing
Connect standard 58mm or 80mm thermal receipt printers without vendor lock-in. The LeadsKE C# agent parses receipts in memory and pushes raw ESC/POS bytes directly via USB raw socket or TCP.
// LeadsKE POS Agent C# (.NET)
var printer = new EscPosPrinter(port: "/dev/usb/lp0");
printer.Initialize();
printer.Bold(true).TextCenter("POS.LEADSKE STORE #01").Feed();
printer.PrintQrCode("https://pos.leadske.com/r/8492");
printer.PartialCut();Electrical Protection: Raspberry Pi GPIO operates at 3.3V logic. Always use isolated optical relays or dedicated RJ11 controller modules for 12V/24V high-current devices.
