Description
# BLUETY Bluety is a set of PCBs for a blue case featuring an RC2014 computer: - a Front panel with cutouts for buttons, LEDs, switches, I/O pin headers, a power button and an LCD display - a Back panel with cutouts for switches and connectors - a Blink'n Switch I/O PCB fixed on the front panel - a Blink'n Switch Bus Daughter PCB for connection to the RC2014 bus The blue case can be bought at [Bangood](https://www.banggood.com/250x190x110mm-Blue-Metal-Electronic-Enclosures-DIY-Power-Junction-Box-p-1067251.html?cur_warehouse=CN). ## Front panel The front panel feature holes for: - Blink'n Switch devices (switches, inputs, outputs, leds) - a 4x20 LCD screen like [this one at Banggood](https://www.banggood.com/IIC-I2C-2004-204-20-x-4-Character-LCD-Display-Screen-Module-Blue-p-908616.html?cur_warehouse=CN) - a 20mm diameter Power Button like [this one at Banggood](https://www.banggood.com/5-Pin-19mm-LED-Silver-Steel-Push-Button-Latching-Power-Switch-Waterproof-12V-p-1260617.html?cur_warehouse=CN) - LEDs for the 0x0D output port (like the status LEDs of the SC126 computer) - screw holes for Blink'n Switch PCB, LCD display, and case corners ## Back Panel The back panel feature holes for: - a 5mm diameter power input - USB input and HDMI output for keyboard/display devices like the [PiZero Terminal RC2014 board](https://www.tindie.com/products/semachthemonkey/raspberry-pi-zero-serial-terminal-for-rc2014/?pt=ac_prod_search) - Flash select and protect switches for [SC126 computer](https://www.tindie.com/products/tindiescx/sc126-z180-sbc-motherboard-kit/) - screw holes for switches, connectors and case corners ## Blink'n Switch PCB Blink'n Switch is an I/O PCB aimed at RC2014 computers and more specifically for the SC126. It is fixed on Bluety front panel and features: - two I/O ports with : - an input section with 8 LEDs, 8 on/off switches, one 8 pin header and one on/off switch for LEDs - an output section with 8 LEDs, one 8-pin header and one on/off switch for LEDs - a +5V/GND pin header - one 8 LEDs status section directly controled by output on the 0x0D I/O port (compatible with SC126 Firmwares) It has cutouts to let space for an LCD display board and the power button. ## Blink'n Switch Bus Daughter PCB This PCB is an RC2014 bus board which relays the bus signals to Blink'n Switch PCB.
