I'm a dedicated hardware developer with a passion for creating innovative, open-source technology solutions. My focus is on modernizing retro computers, developing communication devices, and advancing keyboard technology. Join the journey to support and contribute to these innovative projects.
Screen Board is a DIY project that combines a keyboard and a screen, allowing users to create a retro-futuristic typing experience. The project is accessible as almost all components can be bought off the shelf without the need for soldering, utilizing 3D printing for customization.
T-Keyboard S3 Pro featuring default firmware and I2C expansion mode, with a dual-core LX7 microprocessor, 2.4 GHz Wi-Fi & Bluetooth5 (LE), and 14 programmable RGB LEDs. It includes four magnetic connectors and can be expanded up to a 2x3 grid layout.
First time programming still needs a hardware connection to be made between P1.5 and GND, but after that holding the 1st key while connecting USB lands you in the bootloader!
If your board is never used with ch55xduino before, you need to make the ch55x chip enter bootloader mode. You need to disconnect USB and unpower ch55x, connect the pull-up resistor on D+ line (generally a 10K resistor between D+ and 5V, controlled by a push-button or adjacent pads). Then you connect USB. and hit Upload. Also, a blank new chip will enter the bootloader automatically.
