One small board.
Every protocol you need.
IoT Edge Lite is a compact, dual-core edge node built for sensor interfacing and end-of-line deployments. Wired and wireless comms ship onboard — RS485 ×2, RS232, Ethernet, USB, 2G/4G, Wi-Fi, BLE — with OLED, RTC, microSD, and 27 GPIO ready to go.

Onboard Peripherals
What you'd usually solder on, already there.
Display, indicators, time-keeping, storage, GPIO, level translation, and relay drive — every block a typical edge deployment adds is on the board from the factory.
0.96" OLED Display
Onboard status & diagnostic readout — no extra harness.
Addressable LEDs
User-controllable RGB indicators for state and alert signalling.
Real-Time Clock
Onboard RTC keeps time across power cycles for stamping events.
microSD Card
Local logging, firmware staging, and offline data buffering.
USB Type-A + Type-C
Host and device ports for external storage, programming, and bridges.
GPIO Headers
27 digital I/O brought out for sensors, switches, and actuators.
Logic-Level Converters
Speak 1.8 V, 3.3 V, or 5 V peripherals without adding glue logic.
High-Current Relay Drivers
Drive contactors and motorised loads up to 2.5 A directly.

I/O & Ports
Plenty of pins for real-world signals.
A generous spread of digital, analogue, serial, and PWM lines — enough for the typical sensor cluster, plus headroom for actuators and indicators.

Programming & Deployment
Bring your firmware, ship it your way.
Flash over a USB cable on the bench, or push an OTA build to fleets in the field — both paths are supported on every unit.
Wired programming
Connect via USB Type-C for first-flash, bring-up, and debug. Standard toolchain support, no proprietary programmer.
Over-the-Air (OTA) updates
Push signed firmware to deployed units over Wi-Fi or cellular — roll out fixes and features without truck rolls.
