## Article

**iBoxClient** is the firmware package designed to run on the open-source hardware platform **iBox**, powered by STM32. It serves as a core component of a lightweight IoT system, with its counterpart server software named **iBoxServer**.

#### 🔧 Hardware Overview

The iBox hardware is designed for versatility in IoT applications—capable of acting as either a gateway or an endpoint. Key features include:

**CPU**: STM32F103ZET6

**Power Supply**: 12V DC005 adapter or PoE

**Networking Interfaces**:

**WiFi**: ESP8266

**GPRS**: SIM800L

**Ethernet**: W5500

**LoRa**: SX1276

**I/O Features**:

2-channel relay control output

Digital input detection

1 ADC and 1 DAC channel

This hardware platform is ideal for various IoT scenarios, offering both connectivity and peripheral control.

#### 🧑‍💻 Software Overview

**RTOS**: Based on RT-Thread

**MQTT**: Lightweight message protocol

**Development Status**:

Currently, only low-level drivers are implemented.

Application-layer features are under development.

#### 🛠️ Build Options

The project supports two build systems:

**Keil5**: Project files are under the `/Project` directory

**GCC/Make**: Run `make` from the root directory with optional flags:

`V=1` – verbose output

`DEBUG=1` – enables debug info

`USE_WIFI=1` – switches from default GPRS to WiFi

`USE_RTOS=0` – disables RTOS (default is enabled)

> ⚠️ Note: Only tested with `arm-none-eabi` version 4.9.3 (20150529)

#### 🧰 Tools

A set of useful tools can be found under the `tools` directory.

#### 📉 Project Status

The iBox hardware was originally launched via crowdfunding on **z.elecfans.com**, where it impressively reached **1250% of its funding goal**. However, there has been no visible follow-up project or continued development activity since then.
