New Panel Design
land-boards.com • 06/23/2021 at 15:57 • 0 comments

I made a new panel design which should be easier to use. It has a single 36-pin connector with 4 ground and 4 VCC pins. It moves the connector to the bottom of the card.

It should be easy to use white characters on black P-Touch labels to customize the LEDs and switches. The result should be like:
Jumpers, Switches, and Pushbuttons

Minimal Front Panel Design

LEDs via the LEDS-SWITCHES card.
- D4 = On while fetching instructions
- D3-D1 = SD card status
  - D3
    - on = SD card installed
    - off = SDHC card installed
  - D2 = Read from SD card
  - D1 = Off when running, On when initialization is in progress
  - D0= Off when running, On when initialization is in progress
Pushbuttons
- SW9 - Reset
Jumpers (J3)
- J3-1 to -3 - selects drive type
  - J3-1 installed = RL
  - J3-2 installed = RK
  - J3-3 installed = RH
  - J3-4 to J-6 = unused

Is possible moving this project to Orange Crab ? https://groupgets.com/manufacturers/good-stuff-department/products/orangecrab

and meybe put every switch, led and key on/off as board? Orange Crab have a Lipo

Are you sure? yes | no
