The Signaloid C0-microSD is a tiny programmable FPGA System-on-Module (SoM) that makes it possible to extend your existing industrial automation, manufacturing, and robotics systems with an FPGA-based hardware accelerator. It comes in a microSD form factor, fits in any unused SD or microSD slot, and can be interfaced with as a standard SD block device. This makes it possible, for the first time, to implement hardware acceleration for many data-processing tasks at the edge, even if your system lacks traditional expansion options such as a PCIe M.2 slot! The Signaloid C0-microSD is based on the Lattice Semiconductor iCE40 FPGA. It comes preloaded with a version of our C0 RISC-V processor SoC but you can also load your own custom FPGA designs. A Versatile New FPGA Platform The Signaloid C0-microSD has two main use cases: You can either (1) use it as a hot-pluggable FPGA module, or (2) use it as a hot-pluggable Signaloid C0 RISC-V co-processor module. When plugged into a host computer, it appears as an empty and unformatted SD storage device. You can easily load custom FPGA bitstreams and applications for the built-in Signaloid SoC via the SD interface. [signaloid-in-use-cropped-1_jpg_md-xl] A Hot-Pluggable FPGA Module When using the Signaloid C0-microSD as a hot-pluggable FPGA SoM, you can plug it into your computer, flash new FPGA bitstreams, and then either plug it into a breadboard using a microSD breakout board or integrate it into a legacy (or custom) PCB that has an unused microSD slot. Once powered on, the built-in bootloader will check if the device has been connected to an SD host, and if not, will load the latest custom user bitstream. In this configuration, the C0-microSD offers six configurable I/O pins by repurposing the microSD pads, and five additional I/O pins in the form of test pads. You can find example FPGA designs that you can load onto the Signaloid C0-microSD, along with instructions on how to use them, in the official GitHub repository. [signaloid-horizontal-pinout-v2_png_md-xl] We provide support for the popular LiteX framework for building custom SoC designs that target the Signaloid C0-microSD. As just one example, we have published a demo repository that uses the I2C interface to communicate with an OLED display and a pulse-oximeter sensor. A Hot-Pluggable Co-Processor Module If you don't wish to load a custom FPGA design, the Signaloid C0-microSD comes preloaded with a version of Signaloid's C0 RISC-V processor SoC, which you can use to run your applications. In this mode, host computers can use the SD protocol to exchange data with applications running on the Signaloid C0-microSD. You can do that either by creating custom applications that run on the host platform and that access the SD storage device, or using Unix tools such as dd. You can also integrate the Signaloid C0-microSD into existing embedded systems that feature slots for microSD cards. These range from low-power development boards, to handheld gadgets, to Programmable Logic Controllers (PLCs) for industrial automation. Applications running on the Signaloid C0-microSD's C0 processor SoC can take advantage of a subset of our uncertainty-tracking technology to quantify how uncertainties in data affect their outputs. You can find example applications that use the Signaloid C0-microSD as a co-processor, along with host applications and instructions on how to use them, in the official GitHub repository.

[signaloid-sd-dev-pinout_png_md-xl] When you connect the Signaloid SD-Dev to a host computer via USB, it acts as a generic USB-to-SD adapter, exposing one microSD and one full-size SD slot to the host (peripheral mode). Alternatively, you can attach a Raspberry Pi CM4 to the carrier board, producing a compact SBC with hot-swappable FPGA modules in a standalone configuration. In this mode, the carrier board provides power-measurement capabilities for the on-board FPGA modules and allows you to power cycle them programmatically.

You can find sample code and PDFs of the schematic in the official GitHub repository. We also offer a set of utilities to help you program the Signaloid C0-microSD and develop applications that run on it. The Signaloid C0-microSD is compatible with existing open-source toolchains that can target the iCE40 FPGA, such as Icestorm, Yosys, NextPnR, and Icestudio. We also support AmarathHDL and LiteX. [signaloid-sd-dev-with-c0-microsd-angle_jpg_md-xl] Manufacturing Plan We will outsource PCB fabrication and assembly to PCBWay and handle final programming and testing ourselves, here in Cambridge UK.
