We produce the system on module BlueShark v3 from 2011 and constantly try to keep it a reliable solutions for our clients.

No matter that we do not recommend the BlueShark system on module for new designs we still support it till 2019. Therefore we have updated the design of the module to make it less self-heating and more stable in hot environment. Yesterday we got samples of the BlueShark v3.3 from a factory and tested them. The results are pretty much impressive! If in previous releases we observed the temperature on the table around 50 Celsius degrees, however it dropped to around 40 Celsius degrees now.

Major changes were to the PCB design. We changed the DDR and power planes layout.
