GRiSP Hardware ​

Embedded boards for IoT and real-time systems ​

From IoT and automation to real-time applications, GRiSP hardware supports modular designs. Whether you're prototyping, developing industrial systems or moving towards production, it gives you a practical path from concept to deployment.

GRiSP 2 ​

Modular prototyping for embedded systems ​

GRiSP 2 board

The GRiSP 2 board is a modular prototyping board combining a system on module (SoM) with an IO break-out base board. It features built-in Wi-Fi, USB, Ethernet, and multiple extension ports.

💡 Ideal for: Networked applications, automation, and distributed systems.

Built on feedback from GRiSP 1, GRiSP 2 introduces: ​

  • Bare-metal Erlang for real-time applications.
  • Higher CPU performance & improved I/O throughput.
  • Faster boot times & secure key storage.
  • A modular design for easy production transition.

GRiSP Nano ​

Compact, low-power board for IoT & automation ​

GRiSP Nano

Our newest addition to the GRiSP ecosystem, designed to bring the BEAM to resource-constrained embedded environments. With its compact size and efficient power management, it extends GRiSP's capabilities into IoT, robotics, and automation.

💡 Ideal for: Robotics, sensor networks, and battery-powered devices.

Currently in development ​

The prototype is ready, and we have shown that Erlang/OTP can boot and run in just 16 MB of RAM. Our blog explains the optimisation journey, including memory trimming and the Unicode stub patch.

Work continues on kernel-light and stdlib‑light bundles, energy‑aware boot logic, and preparing a Kickstarter to bring GRiSP Nano into production.
