The small 30x75mm PCB has built-in battery management for a single-cell\nLiPo, microSD card storage, and direct connection via SPI to an Adafruit 4520 1.3\" TFT (ST7789VW controller). It's\nalso designed to be expanded via SparkFun Qwiic/Adafruit STEMMA QT compatible (3.3v only) I2C sensor modules. Finallly,\nit implements the RaspberryPi 3-wire debug connector spec for ARM SWD serial-wire debugging and RS232-style\nUART communication.\n\nThe hardware design files all live in the [`hardware/`](hardware/) folder. See the [`README`](hardware/README.md) in\nthat folder for more.\n\n## Software\n\nThe firmware that the LuLuu runs is contained in the [`software/`](software/) folder.\nIt is written in Rust using some of the amazing Rust embedded tooling.\nSee the [`README`](software/README.md) in that folder for more.\n\n### Installing\n\nYou can either install the firmware using the pre-built binary firmware or you can\nbuild it yourself.\n\n#### Pre-built firmware\n\nYou can install a pre-built firmware easily via USB by connecting the LuLuu PCB to\nyour computer via USB, holding the `USBBOOT` button and then pressing the `RESET`\nbutton. This will put the LuLuu into \"USB Bootloader mode,\" causing a \"USB storage\" \ndevice to appear on your computer, into which you can drop the compiled `luluu.uf2`\n(TODO: link built firmware).\n\n#### Building yourself\n\nTo build yourself, see the [`README`](software/README.md) in the\n[`software/`](software/) folder.\n\n## Licenses\n\nHardware is provided under the CERN Open Hardware License 2.0 Permissive variant.\n\nSoftware is provided under MIT or Apache-2.0 at your choice.\n\nLicense texts available in the [`licences/`](licenses/) folder.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffu5ha%2Fluluu","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Ffu5ha%2Fluluu","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Ffu5ha%2Fluluu/lists"}
