What's included
| Name | Description | Notes |
|---|---|---|
| ips-display-breakout | Breakout for ST7789-based 240x240 IPS display from Aliexpress | |
| library | Directory containing common footprints & libraries | |
| nrf-card | Development board in a size of a credit card containing NRF52832, SD card breakout, ST7789-based display and more | This was done before I discovered that NRF52 consumes 32 uA of current, so it has external RTC and unnecessary powerup logic. |
| sd-card-debug | SD/MMC card breakout board intended for JTAG debugging on Rockchip / Alwinner boards | Codename "dildo" - never ordered |

Questions
How big is the Sd card debug PCB?
It measures 11 × 31.7 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Sd card debug use?
3 parts. 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 Sd card debug KiCad files?
From the dossalab/random-pcbs repository on GitHub, at the commit this page was made from: the board is sd-card-debug/sd-card-debug.kicad_pcb and its schematic ips-display-breakout/display-breakout.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sd card debug design in my own project?
Its repository states no licence, so its author keeps all rights: ask dossalab before reusing the design.
