Squared Computing Services

Services

Embedded engineering, end-to-end.

Embedded firmware, custom hardware, IoT systems, and touchscreen interfaces. Engineered under one roof, from concept to production.

HomeServices

Embedded firmware

Firmware from bare metal to Linux.

We develop embedded firmware across the full range: bare-metal driver layers, real-time task architectures, and embedded Linux distributions. Each codebase is structured, tested, and documented to production standards. You own the source, with the freedom to extend it after the engagement.

BARE-METAL

Bare-Metal Firmware

Tight, deterministic firmware written directly against the hardware, no OS overhead, full control over timing, peripherals, and power.

See details →
RTOS

RTOS-Based Systems

FreeRTOS and Zephyr architectures for multi-tasking embedded products that need reliable task scheduling and power-managed sleep modes.

See details →
EMBEDDED LINUX

Embedded Linux

Yocto and Buildroot-based Linux systems for connected products requiring rich networking stacks, OTA updates, and application frameworks.

See details →
OTA & SECURITY

OTA Updates & Secure Boot

Field-proven OTA pipelines and secure boot chains that keep deployed devices updated, authenticated, and protected after deployment.

Hardware design

Hardware built for manufacturing.

We design custom PCBs with manufacturing considered from the first schematic. The work spans component selection, schematic capture, layout, DFM review, and contract-manufacturer hand-off, with a lean, optimised BOM. Our boards run in outdoor enclosures, kiosk cabinets, and industrial installations across Kenya and beyond.

SCHEMATIC & LAYOUT

PCB Design

From microcontroller selection to final Gerbers, we design boards that are manufacturable, testable, and built to last in real environments.

DFM

Design for Manufacturing

BOM optimisation, DFM reviews, and contract-manufacturer hand-off that bridge the gap between first prototype and volume production.

POWER ELECTRONICS

Power Supply Design

Multi-rail supplies, battery management systems, and MPPT circuits for products powered by mains, LiPo, or solar, from milliwatts to kilowatts.

IoT products

Connected products, end-to-end.

A connected product is a system: hardware, firmware, cloud, and application working together. We engineer all of it, from low-power sensor nodes to LTE-connected industrial gateways across hundreds of field sites. We select the connectivity and architecture that fit your product, and take it to production.

CONNECTED DEVICES

End-to-End IoT Products

We take your product from concept to deployment: hardware, firmware, cloud backend, and mobile app, under one engineering roof.

See details →
CLOUD & API

Cloud Integration & APIs

RESTful and MQTT backends that connect your devices to dashboards, third-party platforms, and mobile apps, reliably and at scale.

See details →
PROTOCOLS

Wireless & Protocol Integration

LTE, LoRaWAN, BLE, Wi-Fi, Modbus, CAN, we select and implement the right communication stack for your product's range, power, and data needs.

MOBILE

Companion Mobile Apps

Android and iOS apps that give users and operators real-time visibility into their devices, pairing, monitoring, configuration, and alerts.

HMI development

Interfaces built for the field.

We design and build touchscreen interfaces for embedded products, from 10-inch industrial kiosks to compact 2.8-inch MCU status displays. Qt/QML on embedded Linux delivers GPU-accelerated rendering; LVGL runs the same quality on microcontrollers without a Linux stack. Both are built to operate in production conditions: high brightness, gloves, dust, and continuous use.

Qt / QML

Qt/QML Interface Development

High-performance touchscreen UIs built with Qt/QML on embedded Linux, smooth animations, offline-capable, and production-hardened.

See details →
LVGL

LVGL on Microcontrollers

Beautiful, lightweight GUIs on resource-constrained MCUs using LVGL, ideal for small displays that don't need a full Linux stack underneath.
