Unfortunately trade tensions and tariffs have caused our costs to go up. We are adjusting our prices to you to cover those costs as our suppliers pass those costs onto us (I assure you, that contrary to statements by politicians, the suppliers are NOT eating the tariffs!). Bare printed circuit boards will generally go from $5 to $6 and assembled and tested products will be evaluated as we exhaust current stock. Most of the parts come from Asia and are affected, also general inflation has forced our assembly contractors to raise their rates. The good news is that tariffs are not applied to shipping costs, which are significant, so you won't see 55% price increases.
