Hardware: GRiSP 2 Board
The GRiSP 2 board is a compact, modular prototyping board made from a System on Module (SoM) and an IO break-out base board, featuring built-in Wi-Fi, USB connectivity, and multiple ports for various extensions. Based on user feedback, GRiSP 2 offers enhancements like real bare-metal Erlang, support for Elixir via Nerves and Linux, more CPU power, ultra-fast boot times, an Ethernet port, and improved IO throughput. Its modular design simplifies the move from development to production, with backward compatibility for Erlang projects.Below are the full specifications for the GRiSP 2 board.

Real-Time Embedded Operating System
RTEMS + Erlang = GRISP
Erlang, a programming language designed for scalable, networked software systems with built-in support for concurrency, distribution, and fault tolerance, is integrated with RTEMS, a hard real-time embedded operating system. This combination provides minimal latency and high responsiveness for embedded systems.
Expandable and Customizable
Digilent Pmod™ Compatible:
The GRiSP 2 board supports Digilent Pmod™ Compatible accessories, providing access to affordable, ready-to-use expansion modules with sensors (such as accelerometers, gyroscopes, temperature sensors, and GPS) and actuators (including motor drivers, RC servos, and audio outputs).
I/O Simplicity
1-Wire Bus
The 1-Wire connector allows connection to many 1-Wire compatible sensors and actuators with just one data wire and a ground wire. It supports longer wires, making it ideal for distributed sensor networks.
