MOS 6530 RRIOT / MOS 6532 RIOT FPGA replacement
Overview
The reDIP RIOT is an open source FPGA board which combines the following in a DIP-40 size package:
- Lattice iCE40UP5K FPGA
- 1Mbit FLASH
- 5V tolerant I/O
The reDIP RIOT provides an open source hardware platform for 6530 RRIOT / MOS 6532 RIOT replacements.
Designs for the iCE40UP5K FPGA can be processed by yosys and nextpnr.
I/O interfaces
DIP-40 header pins:
- 5V input
- 35 FPGA GPIO
- 3 FPGA open-drain I/O
- GND
All FPGA header I/O is 5V tolerant, and can drive 5V TTL.
SPI / programming header:
A separate header footprint is provided for (Q)SPI flash programming, with pinout borrowed from the iCEBreaker Bitsy.

Questions
How big is the ReDIP RIOT PCB?
It measures 17.8 × 50.8 mm and has 4 copper layers, 1.61 mm thick.
What parts does the ReDIP RIOT use?
45 parts, built around the ICE40UP5K-SG48I, 74AHCT1G14SE, AT25EU0011A-SSHN-T and BAS16W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ReDIP RIOT KiCad files?
From the daglem/reDIP-RIOT repository on GitHub, at the commit this page was made from: the board is hardware/reDIP-RIOT.kicad_pcb and its schematic hardware/reDIP-RIOT.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ReDIP RIOT design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
