...It unlocks the possibility to easily make improvements and updating your design, as you will be able to make design modifications, add a silkscreen layer, resize drill diameters, create a soldermask layer to protect copper areas and to avoid accidental shorts, convert a single-side design into a double-side or multi-layer design,… all that just by editing your image with your preferred image editor.

HelloWord-Keyboard is a high-end modular keyboard platform where both the hardware and firmware are designed from scratch to provide deep customizability and advanced features. The project comprises a main keyboard PCB (STM32F103), a dynamic module (STM32F405) with additional features like an e-ink screen, OLED display and a haptic/motorized knob, a base/dock module with USB hub functionality, and other supporting PCBs. The firmware includes high-speed scanning of keystrokes, RGB lighting control via SPI/DMA, HID keyboard enumeration, multiple key-layer mapping and non-volatile configuration storage. ...

AVR128DA /Atmega128 microcontroller based open source EID smartcard with RSA (512-2048) and ECC (prime192v1, prime256v1, secp384r1, secp521r1 and secp256k1) support. Compatible with MyEID card from Aventra. Supported in windows and linux by opensc package. Allow about 64KiB space for keys/certificates. PKCS#15 structure supported. USB token with CCID interface based on xmega128a4u with same features as card. High speed AVR multiple precision arithmetic: squaring, multiplication, exponentiation.

...A listing of the top-layer jumper wires is included.

...Succeeding PCB revisions what contain redesign changes can be merged with existing project setup data. Inconsistencies are highlighted to solve them by new assignements and unused feeders can be cleaned up with a single push. Finally a machine program is generated in Heeb HE50 format and downloaded to the machine interface.
