SIM868 mini Development Board Description
The SIM868 mini Development Board is a compact and integrated module designed specifically to be used on products and save a lot of time handling GSM & GNSS power, RF circuits and etc. The SIM868 EVB (Evaluation Board) exposes the SIM868 module, a complete Quad‑Band GSM/GPRS cellular module with integrated GNSS (GPS/GLONASS/BDS) in an easy‑to‑use board form. The EVB presents the module’s LCC+LGA form factor and standard interfaces (UART, USB2.0, GPIO, etc.) on accessible connectors and test points, so you can prototype, integrate, and validate cellular + satellite‑navigation functions quickly without custom PCB development.
SIM868 mini Development Board Features
- Cellular & GNSS combined: Quad‑Band GSM/GPRS plus integrated GNSS (GPS/GLONASS/BDS) on one board.
- Multiple interfaces: Exposed UART, USB2.0, GPIO and other common signals for flexible integration.
- Compact form factor: LCC+LGA module footprint supported; EVB provides pads and connectors for rapid testing.
- Easy integration: Industry‑standard interfaces and abundant extension pins simplify connecting sensors, microcontrollers, or host systems.
- Development friendly: Test points, power management, and example connections speed up evaluation and firmware development.

- M2M/IoT telematics and remote monitoring
- Personal locators and safety devices
- Any project requiring combined cellular data and satellite positioning
Benefits of using the SIM868 mini DB
- Faster design cycles: Validate RF, GNSS and interface integration without designing a custom PCB.
- Lower development cost: Save time and expense by using the EVB for prototyping and firmware validation.
- Easier debugging: Accessible connectors and test points make troubleshooting and signal measurement straightforward.
- Flexible experimentation: Quickly test different host controllers, power setups, or peripheral configurations.
- Seamless tracking capability: Built‑in GNSS plus industry‑standard interfaces let you track assets reliably at any location with signal coverage.
The SIM868 EVB therefore helps you develop GNSS‑enabled cellular products more easily and faster while reducing integration risk and initial cost.
