LEDiva™ rev A sent to FAB

Yesterday I sent a new revision of my drop-in NeoPixel board, the LEDiva™, that included the new service mounted battery connector as well as a six pin programming connection.

This is the first step in getting the chip as small as possible. The next revision will replace the through hole version of the ATTiny 85 with a surface mounted version. After that, I will try to add a charging circuit to the board so that the battery can be charged via micro USB cable.

I do still need to work on the firmware to save data to the EPROM so it will remember the last color and pattern selected on startup. I have also thought of a way to select the number of LEDs that are being used so that the more elaborate animations look better.

The LEDiva™ is made to be used with up to 140 LEDs with unique addresses. Since I am mostly just going to sell the controller board, I do not know how many LEDs any one person will be using. So I will like have the default LED number set as 30, then create a scenario were you can use the two buttons to turn more LEDs on or off. Once you exit the LED selection mode, it will remember the number of LEDs. The sequence will likely be something like; press and hold one of the buttons on startup, then press and hold both buttons for 5 seconds to lock in the new settings.

I will do a video of me assembling the first rev A board when it comes back from OSH Park.
