Programming
To program the board you need openFPGALoader.
SRAM programming:
openFPGALoader -b littleBee -c ft2232 bitstream.fsInternal flash programming:
openFPGALoader -b littleBee -c ft2232 -f bitstream.fsJTAG interface firmware update
To update the firmware you need to reboot into a bootloader:
- Disconnect the board from USB and power supplies.
- Short 3.3V line and the first pin of the STM32F042 MCU.
- While shorting the pin, connect a USB cable.
Then update the firmware with dfu-util:
dfu-util -a 0 -s 0x08000000:leave -D firmware.binRevision History
1.0: 2021-02-19
- First version.
- Errata:
- 3.3V supply should be used for VCCX instead of 1.8V supply.
- Power LED is too bright.
- Resistor values on a schematic do not correspond to the available values.

Questions
How big is the Gw1ns2c board PCB?
It measures 20.8 × 51.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gw1ns2c board use?
39 parts, built around the TPS73101DBV and MIC5504-3.3YM5. 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 Gw1ns2c board KiCad files?
From the Disasm/honeycomb-pcb repository on GitHub, at the commit this page was made from: the board is gw1ns2c-board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gw1ns2c board design in my own project?
Its repository states no licence, so its author keeps all rights: ask Disasm before reusing the design.
