This month ProtoStack released version 1.4 of their 28 pin AVR board (get a full kit here). As with the previous releases, they have incorporated changes recommended by customers. Unlike most manufacturers ProtoStack values the opinions of its coustomers and strives to improve their products via coustomer feedback. That is why we chose ProtoStack for all of our protoboard needs..... more after the break

The most notable change is the inclusion of a power supply area. In previous versions you could create a power supply by using the generic prototyping area, but this makes it much easier.

This section allows you to bring unregulated power to the board using a 2.1mm barrel connector or a 2 pin header. The power supply core is a voltage regulator. It is expected that most people would use an L7805, but other regulators would also work.

All in all there are 4 improvements:

• Addition of power supply section
• ISP-6 interface is now 2x3 pin instead of 1x6 pin
• Addition of IDC/Double row header section
• Clearer labelling of power busses
