Some of my breakout designs
For a few months now, we have been testing our design of a flexible breakout board for the Max V line of Altera CPLD chips. It performed very well in our prototype application for lighting control and up to now we are very happy with it. The DeltaBrd is designed for Max V chips in a 100-TQFP package: 5M80Z, 5M160Z, 5M240Z, 5M570Z. The images below show both sides of the board.
The AlphaBrd operates from a single 8V - 12V DC power supply. It provides 3.3V and 5V to other devices by means of two AMS1117 LDO linear regulators. For voltage level translation, it uses one 74(A)HCT245 and one 74LVC245 integrated circuit. An led indicates if the board is powered. There is also a protection diode in case you accidentally reverse the input voltage.
In the course of the last few months, I built and worked with this flexible breakout board in order to test the ATtiny84A, ATtiny44A and ATtiny24A capabilities in a mesh network. It performed very well and satisfied the needs completely. Now, I would like to offer you the chance to use the BetaBrd in your own projects.
