Seven is a rapid‑prototyping platform for low‑cost, low‑power connected IoT devices with integrated LTE cellular connectivity.
Designed for teams moving from concept to deployment, Seven bridges the gap between traditional development boards and finalized products—making it ideal for pilot projects, field trials, and early production runs.
Specification:
- Nordic Semiconductor nRF9151 SiP with integrated LTE-M/NB-IoT modem and GPS
- 64 MHz Arm Cortex-M33
- 256 KiB RAM
- 1 MiB flash
- 6-36 V input voltage
- 2 x mikroBUS™ sockets for easy expansion with Click Boards
- RGB LED
- Passive buzzer
- Programming interface (SWD) via TAG connector
- Industrial temperature range (-40 to 85 Celsius)
The software stack is built on the Zephyr Project, providing a robust, secure, and scalable RTOS foundation. It includes ready‑to‑use modules for over‑the‑air (OTA) updates and cloud connectivity, with primary support for AWS IoT.
By adopting the widely used mikroBUS™ add‑on standard, Seven offers access to thousands of off‑the‑shelf Click Boards. This makes it easy to extend the platform with sensors (motion, proximity, temperature, etc.) or interfaces such as RS‑232, RS‑485, CAN, and more—without custom hardware design.
Seven is open source and open hardware, giving developers complete transparency and control to customize, manufacture, and evolve their products without vendor lock‑in.
This repository contains the KiCad project, documentation, and manufacturing files required to build the Seven hardware board.
