If you are doing a conversion form Zworlds little giant\u00a0BL1100, start by understanding what the jumpers are and how they are connected to your application.\u00a0 Your new design will be dependent on the settings and will likely only need a fraction of the capability of this BL1100 board.\u00a0 We have seen some applications that use most of its functionality, but it is usually just a couple of IO ports and and communications ports…
