v5

Programming header is accessed as you would expect from the silk screen side. This is the last release to use 1206 SMD components and is easiest for DIY'ers.

v6

This uses smaller SMD components and the layout simplified pick and place for passives and hand-assembly of other components. DIY'ers can and should just stick to a previous version of the board (v4) unless they prefer 0605/0805 over 1206.

v4

This fixes #16. Version (v4) matches the latest PCB revision (v4).

v2

• Support IDLE status 0 instead of 96 - Memory 16 will toggle this
• Loading a memory position that has not been set plays error tone

Additional debug options

• Holding UP during power up will enter button-test mode
• Holding DOWN during power up will wipe the memory

Both need a power-cycle to return to normal.
