This time last year we released a new version of our medium sized board. The new version had exposed tracks on both sides which made them easier to see. This change also allowed SMD components to be soldered onto the top side. The Large Style 1 prototyping boards are back in stock with the same design change now applied to it.
The board still has the same breadboard style layout, lead free HASL pad treatment, plated through holes and power busses snaking throughout the board.
