GRiSP 2
Scalable Prototyping for Embedded Systems

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

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.
