Next Hardware

This page aims at defining collaboratively the bitbox v3 options for hardware.

main goals

• not faster or generally bigger than
• hdmi will be nice bit is not for immediate release
• simplify building, allow simple

random points, to be ordered

• 8bpp vs 15bpp palette - undecided.
• uext on the top side
• microSD port (using SDIO ?)
• 1 boot0 jumper + reset switch
• MCU stm32f446rc (180MHz 256k flash 128 RAM)
• swd exposed as he10
• stereo out jack for sound or integrated speaker

mobile oriented

• charging port for lipo battery / external charge regulator - maybe more complex if we want to use USB while plugged
• integrated UDLR/L buttons (maybe others via uext) ? udlr/ab only ?
• interface to 320x240 LCD through SPI port on uext.

fixed console oriented

• vga output (hdmi adapters are cheap)
• interface RGB port through HE10 6-plug (allows several interfaces as well as physical connector shapes, reduces pcb size).
• 1 usb for device / charging maybe two DP/DM jumpers to allow sharing second host.
• 1 usb for host. only active when using powered from usb. will allow us gamepad, keyboard, gamepad.
• interface to nunchuck port ? using i2c uext.
