From the project
Hardware design for modular CNC controller
The heart of controller is Lattice ECP5-series FPGA with 25k logic cells.
RJ45 Ethernet interface to PC (via Wiznet W5500) USB TypeC for re-flashing the FPGA (using RP2040 microcontroller with pico-dirtyJtag firmware) 12-24V DC input for powering the FPGA and basic slot hardware E-Stop signal that inhibits slot outputs in hardware, independant of FPGA gateware PMOD header for future expansion (e.g. controlling the board via SPI from RaspberryPi or something) JTAG header for FPGA debugging SWD header for JTAG probe debugging :) Six 2x13 pin 2.54mm sockets for slots (each has 12 FPGA signals…

Rioctrl controller: common questions
What microcontroller does the Rioctrl controller use?
The Rioctrl controller is built around the RP2040, from the RP2040/RP2350 family.
How big is the Rioctrl controller PCB?
The Rioctrl controller measures 190 × 100 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Rioctrl controller?
260 components, from 74 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Rioctrl controller design files?
From the festlv/rioctrl-hw repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Rioctrl controller design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which festlv chose for the repository.
Can I test firmware for the Rioctrl controller without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
